St. Croix River Crossing construction update
Construction progress on the St. Croix Crossing continued into the winter of 2015-16, though the Minnesota and Wisconsin departments of transportation announced the project’s anticipated opening to traffic was moved from late November 2016 to the fall of 2017.
The DOTs said the roadway portions of the project remain on track. Improvements to Minnesota State Highway 36 and Wisconsin State Highway 64, which will connect to the new bridge, are either complete or on schedule.
During the winter, workers installed rebar for the framework of Pier 13’s columns, the project’s only on-land pier in Wisconsin. Forms were later added to allow for the concrete pours.
Crews completed the last concrete pour for the columns in late February. This spring, workers will use a Ringer Crane instead of segment lifters to place multi-ton bridge segments at Pier 13. Segments placed on the east side of the pier will be transferred on a rail system constructed atop a temporary trestle that was built to minimize impacts to the Wisconsin bluff.
Parts of the river channel were kept open during the winter. The pier columns were constructed to their finished height and were capped off with towers.
By the end of 2015, all of the cross beams that connect an upstream pier column to a downstream one were completed.
Construction crews anticipate attaching bridge segments State Highway 36 approach spans on land in Oak Park Heights, Minn., by early April.
