About this project

Summary of work

The new bridge

The new crossing will consist of two separate bridges parallel and upstream from the existing bridge. They will be concrete box girder structures over the main river channel and precast concrete girders over the back channel. Details:

  • 100 year design life
  • Length: 2593 ft
  • Width: approximately 45-66 ft
  • Two twelve-foot lanes each direction
  • Eastbound acceleration lane
  • Twelve-foot outside shoulders
  • Six-foot inside shoulders

The interchange

The final interchange configuration will provide full movement with no signals between I-90 and Hwy 61 as well as access to the Traveler Information Center and boat launches from all directions. The heavily used westbound I-90 to southbound Hwy 61 will feature a fly-under ramp allowing continuous movement with no competing traffic.

The trail system

The final configuration will provide safe access for users on a 10-foot trail through the interchange without a single crossing with highway traffic. A modified trail system and pedestrian bridge connects riders using the Hwy 61 shoulders south of the project to the dedicated bicycle and pedestrian path on the north end of the project. In addition, access is improved to the Rest Area/Traveler Information Center for users of the trail.

Cost

  • $175-$225 million
