Motorists on Interstate 90 at the Dresbach Bridge will be switched to single-lane traffic in each direction on separate bridges on Friday (Sept. 26) afternoon so crews can patch a small portion of the bridge deck, according to the Minnesota Department of Transportation.
The lane switches are expected to occur Friday afternoon to allow space for construction crews to safely do the patching work. Traffic will be returned Sunday night or Monday morning to the regular routing: single lane each way on the eastbound bridge.
There is a 12 foot width and a 80,000 lbs. weight restriction on I-90.
Hwy 61 will be kept open to traffic at all times during the project but there will be over-dimensional permit restrictions implemented.
The Dresbach travel information center is closed to trucks for the duration of the project.
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 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.
