Hwy 99 bridge will remain closed until December
MANKATO, Minn. — The Highway 99 Minnesota River Bridge at St. Peter is expected to remain closed for construction until the first week in December. Traffic will continue to be detoured to Highway 22 and Le Sueur County Road 21 until the project is complete.
MnDOT and the contractor, Kraemer North America LLC, have been discussing various options to assure the work is completed yet this year. The structural repairs are complete. The final phase of construction work includes removal of the existing lead paint down to bare metal and the reapplication of a new prime/paint system. Additional options under consideration for completing the final phase of construction include heating the enclosed bridge as well as bringing in additional people to complete the work.
The rehabilitation of the historic bridge was originally scheduled to be completed October 31st; however, unplanned extra work has caused the completion to be pushed back. “When working on a historic bridge, you’re going to run into unexpected issues including additional steel repairs. Those repairs include fabricating new steel parts and those take time to arrive on site” said MnDOT construction lead Todd Kjolstad.
The project includes preserving the 1931 historic bridge by strengthening the truss floor beams, repairing the piers and abutment, adding riprap (rocks) around abutments, replacing the bridge deck and sidewalk, adding new lights and repainting the structure the original color of a dark green.
The project was awarded to Kraemer North America LLC in December 2016 with a bid of $4,416,517. Construction work started in March 2017. The project webcam to view construction progress can be viewed at http://www.dot.state.mn.us/d7/projects/hwy99stpeter/.
