Route 79/I-195 Interchange Reconstruction Project Fall River, MA 5. PROJECT ALTERNATIVES 5.1 Introduction PART 1 NEPA Environmental Assessment Terminology: The existing interchange is a complex system of roads and ramps. Readers are encouraged to first read Section 4.3 for a detailed description of the existing interchange and roadway system. In Section 4.3, photos, figures, and text explain the roadways, bridges, and ramp system, as well as roadway and ramp nomenclature. An understanding of the existing interchange will help in understanding the alternatives discussed in this Section 5. The terms at-grade and grade-separated are explained in Section 1.1. The term at-grade is used for the At-Grade (Preferred) alternative because it will replace a two-level elevated structure with a single roadway which directly intersects with other area roads. Ramp connections to I-195 will remain. This section describes the No Build and three Build alternatives: • • • • No Build At-Grade Interchange (Preferred) alternative Two-Way Single-Level Viaduct Interchange (Replacement) alternative Rehabilitation of the Existing Two-Level Viaduct Interchange (Repair) alternative These alternatives resulted from an extensive alternatives analysis process. As discussed in the project history in Section 1.3, the independent Value Engineering Study (VE Study, URS) completed in 2009 recommended modifying the scope of the planned rehabilitation work and suggested alternatives that would remove the viaduct and replace it with a roadway that would be combined with the existing at-grade Route 138/Davol Street as more cost effective. The VE study was followed by the Route 79 and Ramps Improvement Study (Jacobs, 2009) which evaluated the recommendations of the VE study at a conceptual level and concluded that alternatives to remove the viaduct were viable and had merit. MassDOT imitated a more detailed study of alternatives that included the input of stakeholders in Fall River and the region. The alternatives development process is summarized below. Background documents and studies are provided in Traffic Appendix 1, and on the MassDOT project website. Pursuant to the federal Interstate Access Policy, an Interchange Modification Report (IMR) was submitted to FHWA which presented analysis of the alternatives in terms of impacts on the structural and operational integrity of the interstate roadway system, in this case Interstate-195. In a letter dated February 29, 2012, FHWA made an affirmative determination of the engineering and operational acceptability of the At-Grade (Preferred) alternative. The letter is included in Appendix 1, Traffic. In the IMR, and the ______________________________________________________________ Project Alternatives 5-1 Route 79/I-195 Interchange Reconstruction Project Fall River, MA PART 1 NEPA Environmental Assessment Traffic Study, the alternatives are numbered differently than they are in the EA/ENF document. The nomenclature used in the EA/ENF evolved during the alternatives analysis process and was selected for simplicity and clarity in this document. The chart in Section 1.8 compares the nomenclature for the alternatives in the EA/ENF and other traffic studies. 5.2 Alternatives Development The extensive process of developing alternatives to evaluate in the EA/ENF consisted of the following four steps: Step 1: Review Previous Studies These previous studies included MassDOT’s Value Engineering Study (URS Corporation, 2009), the follow-up Route 79 and Ramps Improvement Study (Jacobs, 2009), the city-sponsored Route 79/Davol Street Transportation Study (2008, VHB), the city’s Master Plan, and the city-sponsored Fall River Energy Enterprise (FREE) Initiative (2009). Step 2: Form a Project Task Force MassDOT initiated early public outreach with residents, business owners, local governments, regional agencies and officials, permitting agencies and other stakeholders. A Task Force (discussed further in Section 11.1) was convened to help develop and refine the range of alternatives and to solicit public input on the project. Meetings were open to the public and the Task Force met nine times from January 2010 through January 2011. More than 15 conceptual alternatives were developed, evaluated, and discussed at these Task Force Meetings. A tenth meeting was held on November 16, 2011 to update the Task Force prior to distribution of the EA/ENF. Step 3: Develop Goals to Screen the Initial Conceptual Alternatives Goals were developed as part of the early action of the Task Force. The compatibility of the project to other planned projects in the area was considered, including the City of Fall River’s Route 79 project north of the interchange which is independent of MassDOT’s Interchange Reconstruction Project, the Fall River Energy Enterprise (FREE) Initiative concept to restore portions of the Quequechan River to an open water flow, and the planned South Coast Rail Project. A screening exercise of initial concept alternatives was done in order to identify alternatives for further study. Concept alternatives that would result in a degradation of vehicle levels of service or required extensive adverse land takings were dismissed. Any alternative carried forward for additional consideration was required to meet the following criteria: ______________________________________________________________ Project Alternatives 5-2 Route 79/I-195 Interchange Reconstruction Project Fall River, MA PART 1 NEPA Environmental Assessment 9 Maintain adequate vehicle level of service (LOS D or better) on I-195 and other roadways, 9 Preserve and enhance protected parkland and historic structures, 9 Improve pedestrian/bike circulation and local vehicular access, 9 Improve access to the waterfront. Step 4: Develop Conceptual Alternatives In addition to the original alternative that would have rehabilitated the existing viaduct, over 15 conceptual designs were developed and presented to the Task Force to ensure that a full range of alternatives was evaluated. Several alternatives included variations of a diamond interchange with signals or roundabouts as well as a concept that incorporated collector-distributor roads. A diamond interchange facilitates movements to and from a freeway to a local arterial via two intersections. These alternatives were developed to see if it would be feasible to remove ramps and make some of the roadway right-of-way available for elements of the FREE Initiative or other potential gateway projects. For these options, the existing ramps would be eliminated and new loop ramps to connect to I-195 would be constructed west of Route 79. The diamond interchange concept would require extensive land takings, would impact historic and parkland resources, and would result in adverse impacts to the I-195 interchange traffic operations. The ramp design for this concept would also negatively impact access from Route 79 to the waterfront, as well as industrial, commercial, and cultural properties in the area. This group of alternatives was recommended for elimination by the Task Force. A design concept that would have constructed a new viaduct with fewer structures but would have maintained the existing configuration of the interchange was evaluated and resulted in the Two-Way Single-Level viaduct alternative described in Section 5.5. The rehabilitation of the existing two-level viaduct was included as an alternative as discussed in Section 5.6. The No Build alternative has also been analyzed, as discussed in Section 5.3. Several at-grade concepts were evaluated. At the conclusion of the Task Force process, the at-grade alternative concept was favored over a viaduct concept. Two of the alternative at-grade designs were evaluated further to see if features of both could be combined into one at-grade alternative that would be acceptable to FHWA and carried forward for the EA/ENF environmental document. The primary difference between the two options (referred to as Alternatives 1 and 3 in the Traffic Study provided in the Appendix) was that Alternative 3 had a new roadway connection between Route 79 and Milliken Boulevard, and the other did not. Alternative 1 maintained the ramp connection from I-195 EB to Milliken but the ramp went under Ramp C and E to provide for better vertical roadway gradients. Features of alternatives 1 and 3 were combined into several design refinements made to the proposed intersections along the Route 79 within the project area to maximize the efficiency of the operation of the traffic signal system ______________________________________________________________ Project Alternatives 5-3 Route 79/I-195 Interchange Reconstruction Project Fall River, MA PART 1 NEPA Environmental Assessment including additional lanes, designation of one-way streets and evaluation of alternative signalization schemes. The At-Grade alternative has been identified as the preferred alternative in this document. This alternative addresses the Purpose and Need for the project (discussed in Section 2), as well as other criteria considered during the evaluation. The At-Grade (Preferred) alternative is one of three alternatives (the 2 other options being the Rehabilitation and the Two-Way Single-Level Viaduct alternatives) found acceptable in the Interchange Modification Report (IMR) for engineering and operations. The Traffic Study, provided in the Appendix, includes an explanation of the analysis and refinements to the at-grade alternative that resulted in the At-Grade (Preferred) alternative. A description of the extensive year-long Project Task Force alternatives development and evaluation process is included in the Route 79/I-195 Interchange Traffic Study, July 2011, provided in Appendix 1. A description of the alternatives presented in the EA/ENF, and identification of the At-Grade (Preferred) alternative, is provided below. 5.3 No Build The No Build alternative would continue with emergency repairs to the existing structurally deficient bridges currently underway, resulting in no change from the current repair program. A long-term solution to replace or rehabilitate the structures would still be needed. The No Build alternative has been evaluated in terms of the project purpose and need, and project goals. This alternative would not meet the project’s purpose and need since it would not address • the need to rehabilitate or replace the structurally deficient structures; • the need to reduce life-cycle costs and would require costly and continuing repair to the structures and ramp closures; and • the need to improve substandard roadway geometry. Additionally, the No Build alternative would not address the following project goals: • would not meet the goal to improve connections because Route 79 would continue to not interface with local streets. The No Build alternative would not eliminate the awkward U-turn from Route 79 SB to I-195 (discussed in Section 4.3.6). Traffic volumes on Davol Street would be considerably lower than with the At-Grade (Preferred) alternative because regional (Route 79) traffic would be on the viaduct; therefore, the quality of service for pedestrians and cyclists would be better than with the At-grade (Preferred) alternative. This alternative would not include the shared use path and would not increase opportunities for pedestrians and cyclists to connect to existing path/boardwalk facilities; • would not meet the funding goals of the Accelerated Bridge Program; ______________________________________________________________ Project Alternatives 5-4 Route 79/I-195 Interchange Reconstruction Project Fall River, MA PART 1 NEPA Environmental Assessment • would not meet the goal to improve project area aesthetics. The existing viaduct would remain a negative visual element; • would not meet the goal to minimize impacts to historic and cultural resources because the viaduct would remain a prominent feature adjacent to the National Register-listed buildings; and • would not meet the goal to be compatible with the city’s goals of improving access to the waterfront and improving the appearance of the interchange. 5.4 At-Grade (Preferred) Alternative The term at-grade is used for the At-Grade (Preferred) alternative because it will replace the two-level elevated Route 79 structure with a single roadway which directly intersects with other area roads. Ramp connections to I-195 will remain. The At-Grade alternative is shown in Figures 5-1, 5-2, 5-3, and 5-4 and described in further detail in Section 3. It includes the following elements: • The existing two-level Route 79 viaduct will be completely removed and Route 79 combined with Davol Street within the project area. A new four-lane roadway (two through lanes in each direction) will be constructed that will connect with local roads at three new signalized at-grade intersections and the ramps to I-195; • Signals will be provided at the following new intersections with Route 79/Davol Street: Central Street (identified as Intersection #3 on Figure 5-1), Anawan Street/Pocasset Street (identified as Intersection #2 on Figure 5-1), and the proposed Water Street Connector (identified as Intersection #1 on Figure 5-1). Signals are also proposed at the intersection of the proposed Milliken Connector with Milliken Boulevard (#5) and at the proposed Milliken Connector with Ramp C (#4); • The Water Street Connector will be constructed to improve access to and from the waterfront. The new connector will intersect with the new at-grade Route 79. • Ramp connections will be reconfigured. Table 3-1, in Section 3, provides more information on the proposed ramps; • The Anawan Street Bridge will be reconstructed and will provide increased vertical clearance for rail freight and the proposed South Coast Rail project. • Pedestrian and bicycle accommodations will include a new shared use path, improved sidewalks and pedestrian crosswalks, and pedestrian phases on the signals; • Traffic operations improvements to the Broadway/Columbia Street intersection, south of the interchange project limits, and signal improvements for Milliken Boulevard at Central Street/Durfee Street are proposed; • Existing Connector Street, between Pocasset Street and Milliken Boulevard, will be realigned to allow two-way traffic flow. This will involve a slight realignment of the intersection openings of this local roadway to facilitate two-way traffic flow. Connector Street will provide access to Milliken Boulevard from I-195 EB via Pocasset Street; and ______________________________________________________________ Project Alternatives 5-5 Route 79/I-195 Interchange Reconstruction Project Fall River, MA PART 1 NEPA Environmental Assessment • Three local streets will be modified to work with the new Route 79 configuration. Canal Street will no longer intersect with Broadway Extension but will be continued onto Spring Street. Harbor Terrace will be made one-way northbound from Central Street. Anawan Street will become one-way eastbound. The At-Grade (Preferred) alternative has been evaluated in terms of the project purpose and need, and project goals. This alternative meets the project’s purpose and need in that it would address • the need to rehabilitate or repair structurally deficient structures; • the need to reduce life-cycle costs. The At-Grade alternative would have the least number of structures in the future and the lowest long-term maintenance life-cycle costs; and • the need to improve substandard roadway geometry. Additionally, the At-Grade (Preferred) alternative would address the following project goals: • would meet the goal to improve connections to and from Route 79 to local streets and I-195; would eliminate the awkward U-turn from Route 79 SB to I-195; and would improve conditions for pedestrians and cyclists by adding designated facilities and upgraded street crossings; • would meet the funding goals of the Accelerated Bridge Program; • would meet the goal to improve project area aesthetics by removing the visual impact caused by the existing viaduct; • would meet the goal to minimize impacts to historic and cultural resources because the Route 79 viaduct would be removed from the Historic District and would no longer be a prominent visual element adjacent to National Registerlisted buildings; • would meet the goal to be compatible with the city’s plan to revitalize the waterfront. This alternative would improve local roadway access to the CBD and waterfront; and • would also be compatible with the city’s Master Plan that promotes area projects proposed by others such as a Route 79 boulevard north of the interchange project area and the proposed South Coast Rail project. MassDOT has selected the At-Grade alternative as the preferred alternative. 5.5 Two-Way Single-Level Viaduct Alternative The Two-Way Single-Level Viaduct alternative would replace the existing two-level Route 79 viaduct with a new single-level viaduct, carrying two lanes in each direction. Route 79 would remain grade-separated from local streets as it is today, but on one, less visually intrusive viaduct instead of two. ______________________________________________________________ Project Alternatives 5-6 Route 79/I-195 Interchange Reconstruction Project Fall River, MA PART 1 NEPA Environmental Assessment The Two-Way Single-Level Viaduct alternative is shown in Figures 5-5 and 5-6. It includes the following elements: • The two-level Route 79 northbound and southbound viaduct would be removed and replaced with a new single-level viaduct, carrying two lanes in each direction. This would eliminate one level of viaduct and maintain similar grade-separated interchange movements as existing conditions; • A new ramp diverging from Ramp A would serve local street movements near the waterfront at Davol Street. The new ramp would accommodate a portion of trips currently using Ramp Y (at Milliken Boulevard) to access the CBD and the waterfront; • A new ramp would be provided from Route 79 SB to Davol Street SB, approximately 0.8 miles north of Central Street. The connection would improve accessibility and connectivity to the CBD and the waterfront from the north. The desirable local connection from I-195 EB to the waterfront would still be missing; • Ramp F (I-195 WB off-ramp to Route 79 southbound) would be removed and replaced with a new ramp connection to Central Street. This would eliminate the weave onto Route 79 southbound and Broadway Extension; • New Ramp to I-195 to replace Ramp D; • The Canal Street connection to Broadway Extension/Davol Street would be closed; and • The intersections of Davol Street with Anawan Street/Pocasset Street and Central Street would be signalized. The Two-Way Single-Level Viaduct alternative has been evaluated in terms of the project purpose and need and project goals. This alternative: • meets the project’s need to rehabilitate or replace the structurally deficient structures and • meets the project’s need to reduce life-cycle costs; however, this alternative would have more structures and higher maintenance costs over time compared to the At-Grade (Preferred) alternative. The Two-Way Single-Level Viaduct alternative does not meet the project’s need to improve substandard roadway geometry. Although this alternative eliminates the short weave sections found in the No Build alternative, it would introduce a negative geometric design feature with the tight radius required on the curve formed between the transition from Route 79 to I-195 ramps to avoid impacts to the historic mill buildings. Additionally, the Two-Way Single-Level Viaduct alternative would partially address the following project goals to • meet the funding goals of the Accelerated Bridge Program; • improve project area aesthetics to some extent by replacing the existing two-level viaduct with a single-level structure with cleaner lines and fewer supports; • minimize impacts to historic and cultural resources. However, this alternative would leave an elevated highway structure adjacent to National Register-listed mill buildings and Heritage Park; and ______________________________________________________________ Project Alternatives 5-7 Route 79/I-195 Interchange Reconstruction Project Fall River, MA PART 1 NEPA Environmental Assessment • be compatible with the city’s plan to revitalize the waterfront. The visual appearance of the interchange would improve with a new, single-level viaduct, but the views of and access to the waterfront would be minimally improved. The Two-Way Single-Level Viaduct alternative on the other hand would not meet the goal to improve connections because Route 79 would continue to not interface with local streets. This alternative would not eliminate the awkward U-turn from Route 79 SB to I­ 195 (discussed in Section 4.3.6). Traffic volumes on Davol Street would be considerably lower than with the At-Grade (Preferred) alternative because regional (Route 79) traffic would be on the viaduct; therefore, the quality of service for pedestrians and cyclists would be better than with the At-grade (Preferred) alternative. This alternative would not include the shared use path and would not increase opportunities for pedestrians and cyclists to connect to existing path/boardwalk facilities. Therefore, the Two-Way Single-Level Viaduct alternative was not selected. 5.6 Rehabilitation of the Existing Two-Level Viaduct Alternative The Rehabilitation alternative would reconstruct all elevated structures. It is shown in Figures 5-7 and 5-8 and includes the following elements: • Improvements would include new high-performance concrete decks, steel stringers, bearings, and deck joints. The existing lead-painted steel superstructure would be removed and replaced with a new steel superstructure painted with a modern coating system. Substructure improvements would include repairs and/or replacement of concrete piers and abutments. Existing steel piers would be rehabilitated including cleaning and painting; • A new ramp would be provided from Route 79 SB to Davol Street SB, approximately 0.8 miles north of Central Street. The connection would improve accessibility and connectivity to the CBD and the waterfront from the north; and • New traffic signals on Davol Street at Anawan Street/Pocasset Street and Central Street would be installed. The Rehabilitation alternative has been evaluated in terms of the project purpose and need and project goals. This alternative would partially meet the purpose of the project but address only one of the project needs. • It would address the need to rehabilitate or replace the structurally deficient structures. • It would not address the need to reduce life-cycle costs. Over the long term, this alternative has the most structures and would have the highest maintenance cost. • It would not address the need to improve substandard roadway geometry. Additionally, the Rehabilitation alternative would meet the funding goals of the Accelerated Bridge Program, but it would not meet the goal to improve connections because Route 79 would continue to not interface with local streets. This alternative ______________________________________________________________ Project Alternatives 5-8 Route 79/I-195 Interchange Reconstruction Project Fall River, MA PART 1 NEPA Environmental Assessment would not eliminate the awkward U-turn from Route 79 SB to I-195 (discussed in Section 4.3.6). Traffic volumes on Davol Street would be considerably lower than with the AtGrade (Preferred) alternative because regional (Route 79) traffic would be on the viaduct; therefore, the quality of service for pedestrians and cyclists would be better than with the At-grade (Preferred) alternative. This alternative would not include the shared use path and would not increase opportunities for pedestrians and cyclists to connect to existing path/boardwalk facilities This alternative would not meet the goal to improve project area aesthetics by removing the visual impact caused by the existing viaduct and it would not meet the goal to minimize impacts to historic and cultural resources. This alternative would leave the twolevel elevated highway structure adjacent to National Register historic mill buildings and Heritage Park and it would not meet the goal to be compatible with the city’s plan to revitalize the waterfront. For these reasons, the Rehabilitation alternative was not selected. 5.7 Summary of Alternatives Comparison Project Purpose and Need The purpose of the project is to promote safety by addressing the structurally deficient bridges that are part of the Route 79/I-195 Interchange and thereby reduce life-cycle maintenance costs of the interchange structures. The No Build alternative does not meet the project’s purpose and need. The No Build alternative has not been selected because it would not rehabilitate structurally deficient structures; would not improve safety; and would do nothing to reduce life-cycle costs. The At-Grade (Preferred) alternative fully meets the project’s purpose and need. In addition, the At-Grade (Preferred) alternative meets the need to reduce life-cycle costs to a greater extent than the other alternatives and is the only alternative that meets the goal to improve connections between I-195 and Route 79. MassDOT has selected the AtGrade alternative as the preferred alternative. The Two-Way Single-Level Viaduct alternative mostly meets the project’s purpose and need but, as discussed above, fails to meet the need to reduce life-cycle costs as much as the At-Grade (Preferred) alternative and also introduces a negative geometric design feature in order to avoid impacts to the historic mill buildings. Because of severe right-of­ way constraints, the design features a substandard radius proposed as part of the new design of the viaduct connection from new Route 79 single-level viaduct to I-195 ramps. The Two-Way Single-Level Viaduct alternative has not been selected for these reasons. Rehabilitation of the existing two-level viaduct alternative meets the project’s purpose and need in only one way—addressing the structurally deficient structures. For this ______________________________________________________________ Project Alternatives 5-9 Route 79/I-195 Interchange Reconstruction Project Fall River, MA PART 1 NEPA Environmental Assessment reason, the Rehabilitation of the existing two-level viaduct alternative has not been selected. Project Goals The goals of the project include: improve connections from I-195 and Route 79 and local multi-modal connectivity; meet legislative funding requirements; improve project area aesthetics; minimize impacts to historic and cultural resources; and be consistent with local and regional plans. The No Build alternative does not meet any of the goals of the project. The At-Grade (Preferred) alternative meets all of the goals of the project. The Two-Way Single-Level Viaduct alternative does not meet the goal to improve connections from I-195 and Route 79, and does not improve system linkage by improving conditions for cyclists and pedestrians. The Rehabilitation of the Existing Two-Level Viaduct alternative meets only one of the project goals, the legislative funding goal. Table 5-1 provides a summary of the evaluation of the alternatives in terms of the project purpose and need and project goals. Table 5-2 presents a summary comparison of the environmental impacts for each alternative presented in the EA/ENF. Section 6 provides a detailed discussion of the impacts. ______________________________________________________________ Project Alternatives 5-10 Route 79/I-195 Interchange Reconstruction Project Fall River, MA PART 1 NEPA Environmental Assessment Table 5-1 Summary Comparison of Alternatives with the Project Purpose and Needs and Goals No Build Alternative At-Grade (Preferred) Alternative Two-Way Single-Level Viaduct Alternative Rehabilitation of the Existing TwoLevel Viaduct Alternative X. 9 9 9 X 9 9 9 X X 9 X X 9 X X 9 9 9 9 9 9 X 9 9 9 X 9 9 9 X Purpose and Need Address Structural Deficiencies Reduce Life-cycle Costs Address Substandard Geometry Goals Improve Connections from X I-195 & Route 79 Meet Legislative Funding X Requirements Improve Project X Area Aesthetics Minimize Impacts to Historic and X Cultural Resources Be Consistent With Local and X Regional Plans X does not meet need or goal 9 meets need or goal 99 meets need or goal to greater extent ______________________________________________________________ Project Alternatives 5-11 Route 79/I-195 Interchange Reconstruction Project Fall River, MA PART 1 Environmental Assessment Table 5-2 Summary of Impacts of Alternatives Impact Category Transportation Local Street Connectivity Traffic Operations Level of Service (LOS) No-Build Alternative No change in vehicular connectivity.
