On Oct. 21, 2016, leaders from the Minnesota and Wisconsin departments of transportation gathered with our project partners at the Dresbach Welcome Center to celebrate the strong work and partnerships that built this new Interstate 90 Dresbach Bridge and its connections.
The bridge sits at the confluence of many modes of transportation: roads, rivers, railroads and even a bicycle trail. This new structure spanning the great river not only connects Minnesota and Wisconsin, it connects communities and commerce.
The work that built this structure is expected to last for 100 years. Forty-nine years ago, when officials and community members gathered to celebrate the first I-90 bridge at this site, they, too, took note of the important link it provided to the economic and social lives of our two states.
Nestled into the Mississippi River blufflands, this bridge and its connections to Highway 61/14 are expected to improve safety for motorists, ensure better traffic flow and meld well with the natural beauty of the region.
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 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.
