Street Projects

Engineering construction projects for the current construction season.  For more information please contact Public Works at 507-934-0670.

Just a friendly reminder that there are several areas within the City of Saint Peter that are “CLOSED” for construction. It may include a roadway, a sidewalk or a trail; but closed means closed – no car, truck or foot traffic is allowed in these areas.

Our construction crews are seeing too many people wander onto construction sites to see what is going on – a reminder that this is a violation of the law and can be enforced.


Thanks for your help in keeping the work site safe.

Highway 99 Bridge at St. Peter to close for construction March 8

Early project start means early finish

MANKATO, Minn. – The Highway 99 Minnesota River Bridge at St. Peter closed for construction on Wednesday, March 8.  Traffic is detoured to Highway 22 and Le Sueur County Road 21 until the project is completed in early October.

The Highway 99 Bridge preservation project was initially slated to begin around April 3, however MnDOT is allowing the contractor an early start to perform work over the river with current low water levels to prevent the establishment of migratory bird nests.  The work includes a sheeting that will prevent nesting and catch any debris before it falls into the river. Working in a river is often a dynamic situation and MnDOT is obligated to be sensitive to its natural resources.  Starting the work in early March moves the completion date from late October to early October.

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 detour will also accommodate work that will take place later in the construction season including an upgrade to the UP Railroad crossing east of the bridge and the City of St. Peter project on Highway 99/Broadway from Minnesota Avenue to the Minnesota Bridge. 

A detour map and more information can be found at .

The project has been awarded to Kraemer North America LLC with a bid of $4,416,517.
