MnDOT I-35W/TH 62 Crosstown Commons Reconstruction

Minneapolis & Richfield, Minnesota

SRF was selected by MnDOT to complete a number of design tasks for the rebuilding of the $300 million I-35W/Highway 62 Crosstown Commons, one of the most significant reconstruction projects in the Twin Cities area. The largest component was eliminating the shared lanes and weaves in the I-35W/ Highway 62 interchange on the border of Richfield and Minneapolis. SRF helped complete this difficult design challenge, in addition to preliminary designs, traffic forecasting and operations analysis, environmental documentation, final PS&E, and right of way acquisition.

SRF’s support led not only to a successful outcome, but the final design was safe and efficient, allowing traffic through the corridor while construction took place.

The following major elements were completed:

  • Reconstruction of four miles of I-35W, two miles of TH 62, and nine interchanges.
  • Construction of 26 bridges, 10 miles of retaining walls, and eight miles of noise walls.
  • Placement of more than six miles of new storm sewer pipe, ranging in diameter from 15 to 120 inches.
  • Adding HOV lanes along I-35W through the entire project area, a general purpose lane along I-35W north of TH 62, and two dedicated lanes in each direction on TH 62 to separate it from I-35W.
  • Creating space in the 
I-35W median for the region’s first median BRT transit station, which is located at 46th Street in Minneapolis.
  • Including transparent noise barriers that maintain views of Minnehaha Creek.
  • Minimizing closures during construction to limit the flow of traffic.
  • Four major stages of work zone traffic control, with local and regional signed
    detour routes.
