All lane restrictions have been lifted for the winter. Winter work will mainly focus on the main channel bridge, muck excavation, and retaining walls.
Access to the Traveler Information Center and Lock and Dam is currently restricted to passenger vehicles. Access to the US Fish and Wildlife boat launch from the Dresbach Travel Information Center is now open to the public. To access the USFWS boat launch, anglers should follow the route delineated with orange barrels. MnDOT crews will continue to plow the access route and landing parking lot throughout the winter. The USFWS boat launch will remain open until March 2014 when construction activities resume. The Department of Natural Resources boat landing at the site will continue to remain open at all times during the project.
I-90 currently has a 14 foot width restriction throughout the project.
Hwy 61 will be kept open to traffic at all times during the project but there will be over-dimensional permit restrictions implemented.
The existing Dresbach travel information center will be closed to trucks for the duration of the project starting in the spring of 2013 and ending in the fall of 2016.
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.
