Hwy 24 bridge construction

Mississippi River in Clearwater

Hwy 24 bridge

Construction in progress


Hwy 24 worksite in November 2015. Work continues on the new Highway 24 bridge over the Mississippi River in Clearwater, which began Aug. 15, 2015.

A webcam has been recently installed at the jobsite. Viewers can go online anytime and see the latest digital image taken by the webcam.

Construct piers, abutments
Crews will continue to construct bridge abutments and six piers from west to east across the river over winter. Two piers are inland and four are in the river. Cofferdams, made from steel sheet pile are driven into the riverbed and create a dry space to work in the river. Steel pile is driven deep into the earth to help form the foundation for the piers. Then piers are constructed inside the cofferdam. Location map - click on map for pdf version

A temporary road known as a causeway is constructed from the west river bank out into the water to access the worksite. Poster of work stages, details

This work will continue through mid summer 2016.

Please stay out of fenced off work areas and equipment, both on land and in the river, for your safety and ours.

Project overview

This project will replace the 57 year-old Highway 24 bridge spanning the Mississippi River and CR 7/Main St in Clearwater in Sherburne and Wright counties. The new bridge will be built just southeast, or downstream, from the current structure.

Existing Hwy 24 bridge
The current Hwy 24 bridge will remain open to traffic as the new one is built.

The river crossing serves commuter, freight and recreational traffic, with current average daily traffic volumes of 14,800 and forecast volumes of more than 30,000 vehicles per day in 2040.

The existing bridge was built in 1958 and is due for replacement. Shoulders are narrow and do not provide adequate room for handicap accessible vehicles, and sidewalks do not meet today's ADA requirements. 


The new two-lane bridge structure will include wider lanes, shoulders and a pedestrian sidewalk/trail separated by a concrete barrier for improved access and safety.
