PROPOSED SCOPE OF WORK FOR I-94/T.H. 280 CONCEPT DEVELOPMENT
SP 8816-1438
Background
The Contractor is required to conduct all tasks as described below on I-94 from T.H. 65 in Minneapolis to Cedar
Avenue in St. Paul. The project length is approximately 9.0 miles on Interstate 94. This will also include the study
of T.H. 280 from I-94 to Larpenteur Avenue/Hennepin Avenue.
Mn/DOT has developed two projects on I- 94 which rehabilitated the inside and outside shoulders, resurfaced the
inplace roadway, upgraded the inplace drainage system, and installed lane control signals. These projects are
consistent with the Minor Rehabilitation with ATM alternative developed in the I-94 Managed Lane Study
completed in January of 2010.
The I-94 Managed Lane Study also developed an alternative that would reconstruct I-94 to provide a managed lane
through the I-94 corridor between downtown Minneapolis and downtown St. Paul. As stated in the study, the
reality of funding the reconstruction of I-94 to facilitate additional capacity is unlikely, based upon the current
funding sources available to Mn/DOT.
The goal of this study is to develop concepts for the reconstruction and reconfiguration of the I-94/T.H. 280
interchange to facilitate a managed lane being carried through that interchange and the development of concepts for
direct connections to and from downtown Minneapolis and St. Paul to the managed lane. The tasks associated with
this contract will be project management, public outreach, traffic forecasts, concept development, operational
analysis, and cost estimates.

Traffic Modeling
Develop 2035 daily and AM/PM peak hour forecasts for alternatives for the re-construction and
2
reconfiguration of the I-94/T.H. 280 interchange, provision of access into and out of a managed lane on
Interstate 94 in Minneapolis, and provision of access into and out of a managed lane on Interstate 94 in St.
Paul, using the Twin Cities Regional Travel Demand Forecast Model (TCRM). The study area includes the
I-94 and T.H. 280 corridor segments between T.H. 65 in Minneapolis, Cedar Avenue in St. Paul,
Larpenteur Avenue/Hennepin Avenue to the north, and I-94 to the south. The following travel demand
volumes will be developed for the interchange study area:





Base year existing conditions (2010)
2035 No Build (existing network plus planned improvements from current TPP)
2035 Build Alternative 1
2035 Build Alternative 2 (if needed)
Year of Opening Build (2015) (Preferred Concept)
3.1
Highway network assumptions and transit network assumptions for the 2035 No Build forecast will be
consistent with the Metropolitan Council 2008 Transportation Policy Plan, and will include the UPA
project on I-35W south of downtown Minneapolis, and proposed I-94 MnPASS Lane between downtown
Minneapolis and downtown Saint Paul. The travel demand forecasting process and files used to conduct
the I-94 Managed Lanes Study completed by Parsons Brinckerhoff in November 2009 will be provided for
use in this study.
3.2
Socio-economic data assumptions will be consistent with the Metropolitan Council 2008 Transportation
Policy Plan. However, refinement of the Transportation Analysis Zones within the study area was
completed for the I-94 Managed Lanes Study, and should be used for this effort.
3.3
A technical memorandum summarizing the travel demand forecasting methodology, assumptions, and
findings will be prepared for review by Mn/DOT’s Metro District and the Metropolitan Council. This
document will adhere to the guidelines and address the reasonableness checks as indicated in the May 10,
2006 Mn/DOT Memo "Revised Guidelines for Twin City Travel Demand Forecasts Prepared for the
Metropolitan District". Traffic forecasts are not complete until the travel demand methodology,
assumptions, and checks for reasonableness, described within the Traffic Forecasting Memo, are reviewed
and approved by Mn/DOT. Traffic forecasting documentation needs to be reviewed by the Metro District
Traffic Forecaster and traffic forecasts must be approved prior to use in the CORSIM modeling and
analysis.
3.4
Contractor Deliverables:
 Document summarizing methodology and assumptions used to develop forecasts and subsequent
reasonableness checks.
 Forecasts for the following scenarios: 2035 No Build, 2035 Alt 1, 2035 Alt 2, and 2015 Build,
including average annual daily traffic, AM peak hour and PM peak hour, and estimated heavy
commercial vehicle traffic.
 One paper and one electronic copy in MS Word of the draft report, three copies of the final report plus
one electronic copy in pdf and one MS Word copy.
 Graphic representations (i.e. maps) of existing and forecast for all scenarios.
3.5
Optional:
The Twin Cities Regional Travel Demand Model is not validated to the peak hours. At a minimum, close
scrutiny needs to be given to peak hour forecasting in relation to existing travel behaviors, which is
addressed in the Mn/DOT Traffic Forecasting guidelines referenced above. In addition, Mn/DOT is open to
innovative ideas and suggestions for improving peak hour modeling forecasting.
