WSB was brought onto the I-35W North MnPASS design-build project to help provide a lasting, sustainable option for highway users passing between the City of Roseville and the City of Lino Lakes. The design-build delivery method was chosen in hopes of reducing cost and overall project duration.

Project Details Included:

  • The addition of a MnPASS lane from County Road C in Roseville to Lexington Ave in Blaine
  • Drainage improvements
  • Resurfacing of mainline and drainage ramps
  • Replacement of 5 overpass bridges
  • Bridge deck rehabilitation of I-35W/TH10 interchange
  • Construction of 7 post-wood plank noise walls

The team was required to maintain existing traffic lanes throughout the entire construction process, while ensuring the safety of staff and road users. The solution was to utilize multiple narrow “chute” lanes, which allowed existing lanes to be maintained and construction to continue. The chute lane innovation reduced traffic control costs and the contractor was able to perform work in multiple areas, mitigating potential delays.

The project improved pavement conditions, increased mobility, and enhanced travel time reliability for transit and non-transit users on I-35W between TH 36 and Sunset Avenue. The I-35W North MnPASS project was completed utilizing the design-build delivery method, reducing the project duration from four to three construction seasons.
