Freeway System Interchange Study

The Metropolitan Council is partnering with the Minnesota Department of Transportation (MnDOT) to conduct a study of about 50 locations where at least two freeways meet. Examples of these locations include:

  • I-35W at I-694 in Arden Hills and New Brighton
  • I-94 at I-494 / I-694 in in Oakdale and Woodbury

People require interchanges that allow various forms of transportation to move freely and safely whether driving, using public transit or carrying freight. As crashes happen and traffic volumes grow, we need to plan safer, more efficient designs that keep people moving.

Like the Congestion Management and Safety Plan (PDF), MnPASS, and the Principal Arterial Intersection Conversion studies, the interchanges selected in this study will be considered for inclusion in the 2040 Transportation Policy Plan. This study will:

  • Address congestion and the concentrations of crashes at interchanges in the Twin Cities Metropolitan Area
  • Research the level of congestion, reliability, safety, freight, and transit at each interchange
  • Identify high priority interchanges for further analysis
  • Consider a range of alternatives at each priority location
  • Evaluate each alternative for its benefits and costs

The selected projects can improve the Twin City’s freeways at these targeted locations to continue supporting and improving economic vitality and quality of life in our region.

The anticipated schedule:

  • September 2018 through early 2020 — Monthly Technical Advisory Committee meetings
  • Early 2019 — Priority evaluation results
  • End of 2019 — Draft of final report with investment priorities

Draft study locations

Study participation

The Technical Advisory Committee provides a forum to shape this study with participation from staff who represent:

  • The seven counties in the metro area
  • Wright and Sherburne counties
  • Municipal governments
  • Federal Highway Administration (FHWA)
  • MnDOT
  • The Metropolitan Council

Agency staff and the consultant, SRF Consulting Group, Inc. will share key milestones with a number of transportation-related standing committees in the region including the region’s Transportation Advisory Board, its subcommittees, the Congestion Management Process Advisory Committee, and the Minnesota Freight Advisory Committee.
