Route 2/I-95 Bridge Replacement Project Summer 2014 About the Project The Massachusetts Department of Transportation (MassDOT) is replacing the east and westbound Route 2 bridges over Interstate 95 (I-95) in Lexington as part of the Route 2/I-95 Bridge Replacement Project. Route 2 is one of the main east-west alternatives to the Massachusetts Turnpike and carries approximately 67,000 vehicles a day. Built in 1960, the bridges are deemed “structurally deficient” and “functionally obsolete.” The project will address the current deficiencies, improve safety and reduce expensive annual maintenance costs. It will also make improvements to I-95 in the area. The Work construction for high quality, uniform, long-lasting pavement. “Intelligent Compaction” uses vibratory rollers equipped with an onboard computer reporting system and Global Positioning System (GPS) mapping. The process provides the operator with an on-board, real-time record of the location and number of roller passes as well as compaction data. In an effort to minimize potential inconveniences, MassDOT is committed to maintaining three travel lanes in each direction on Route 2 during peak hours. Travel will be restricted at times to one lane in each direction, for a limited duration during off-peak hours. Additionally, a minimum of four travel lanes and an auxiliary lane in each direction on I-95 will be maintained during the peak hours of 6 AM to 10 AM and 3 PM to 7 PM. Innovative Accelerated Bridge Construction (ABC) techniques will be used to construct the bridges, Project Limits minimizing disruption and construction duration and The project is located in Lexington, and extends from reducing environmental impacts. ABC techniques Old County Road in the west near the Lincoln town line include the first-time use in Massachusetts of precast, to Spring Street in the east. The area is home to many modular concrete abutments instead of a deep high tech and biotech businesses. It also abuts the foundation system using numerous drilled shafts. watershed of the Cambridge reservoir, the main water The new 334-foot, two-span, steel plate girder supply for the City of Cambridge. (See map on reverse.) replacement bridge will be constructed in two phases. Once complete, the bridge will have three travel lanes, one auxiliary lane and two Projected Schedule shoulders in each direction. MilestoneDate Other project benefits include realigning and reconstructing portions of Route 2 to improve vertical clearance over I-95 and upgrades to stormwater drainage and treatment. As part of the project, a two-mile stretch of I-95 will be resurfaced and will include a new median, guard rails, wider shoulders, new roadway markings and improved stormwater drainage. The project also features MassDOT’s first use of “Intelligent Compaction.” Compaction is one of the most important processes in roadway 1 Route 2/I-95 Bridge Replacement Project Construction Begins* June 2014 Bridge Design Complete January 2015 Highway Design Complete April 2015 Construction Substantially Complete November 2016 This project is using the design/build approach, where final design is completed in packages that are reviewed and released by MassDOT to begin work immediately on the critical elements. * Contact Us Interested in staying in touch with this project?
