Highway 99/169 intersection at St. Peter closed starting July 7 for J-Turn construction

Intersection improvement construction moves to stage 2

MANKATO, Minn. – Construction to improve intersections on Highway 169 at Highway 22 and 99 at the south end of St. Peter have progressed to the next stage, according to the Minnesota Department of Transportation. Starting Friday, July 7, Highway 99 just west of St. Peter will be closed as crews continue to construct a J-Turn at the intersection with Highway 169.
Highway 99 traffic will be detoured to Nicollet County Roads 40, 5, and Broadway Avenue until the completion of the J-turn construction in mid-September.

Additionally, Highway 169 traffic at the south end of St. Peter will be reduced to two-way traffic in the northbound lanes.

Motorists can continue to expect lane restrictions, detours, and traffic delays during construction. Drivers are encouraged to allow for extra travel time.

This summer’s intersection improvement projects in St. Peter includes adding a second left turn lane on southbound Highway 169 at the intersection with Highway 22 to create a dual turn lane.  A J-Turn will also be constructed at the intersection with Highway 99. Construction is expected to be complete in October, weather permitting.

Traffic impacts

Highway 169 through St. Peter remains open to traffic during construction.

A temporary traffic signal remains at the intersection of Highway 169 and Elm Street to aid in traffic and pedestrian movements during construction. There are right turns only at Minnesota Avenue, Pine Street, Jefferson Avenue, Wabasha Street and Washington Avenue. Access to Highway 169 from Wabasha Street will be permanently closed as part of this project.

Highway 22 south of St. Peter remains closed to traffic until the completion of the project in October. Traffic is detoured to Highway 99, Le Sueur County Road 21 (Golf Course Road), and Shanaska Creek Road.

Access to St. Peter Riverside Park located on Highway 22 south of St. Peter is closed to motorists during construction. Visitors are encouraged to access the park via the walking trail.
Traffic restrictions are expected to change throughout different stages of construction. Detour maps, including a detailed interactive map, are available on the project website:  https://www.dot.state.mn.us/d7/projects/hwy169-22-99/index.html.

Benefits of the project include improved pavement, intersection safety, and traffic flow on the south side of St. Peter. Mathiowetz Construction was awarded the project with a bid of $8,124,440.87.
