Eastbound I-90 Exit to Southbound Hwy 61

The La Crescent exit from Eastbound I-90 (Dresbach to La Crescent) is now from the left lane and it is earlier than the previous exit, which was on the right. Here's a short video captured using a GoPro camera mounted to the vehicle which shows the new exit, on the left.

Westbound I-90 to southbound Highway 61 will continue to detour through Dresbach until spring 2016. Visit the Dresbach Bridge Project on Facebook.
Northbound Highway 61 to Westbound I-90 (La Crescent to Dresbach)

Motorists traveling on Northbound Highway 61 heading towards Westbound I-90 (La Crescent to Dresbach) should veer left to access Westbound I-90. The first right exit from Northbound Highway 61 will take drivers to Eastbound I-90. The second right exit from Northbound Highway 61 will take drivers to the Traveler Information Center and Lock and Dam area (The Traveler Information Center will remain closed until May 2016). As always, please obey the posted speed limit and pay close attention while traveling through the construction zone. Here's a short video captured using a GoPro camera mounted to the vehicle which shows this new configuration.

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

  • $187.5 million
