Hwy 99 Nicollet to St. Peter construction starts May 3 with detour

MANKATO, Minn. — Hwy 99 motorists from Nicollet to St. Peter are advised to expect a detour beginning Monday, May 3 as construction begins on the 11-mile corridor. A detour will remain in place until the completion of the project in August.

Traffic will be detoured in two stages during construction. Stage 1 of the detour will begin on Monday, May 3 and traffic will be detoured to Hwy 111, and Nicollet County Roads 5 and 40.

The stage 2 detour will have traffic detoured to Hwy 111 and Nicollet County Road 5 and continue to the intersection with Hwy 169. The stage 2 detour will be utilized for two weeks to allow for culvert work on the eastern end of the project. The stage 2 detour will tentatively begin in mid-June, weather depending. Stage 1 of the detour will be in place until the end of the project in August.

The project includes resurfacing 11 miles of Hwy 99 from Birch Street in Nicollet to the south intersection with Hwy 169 in St. Peter, replacement of box culverts, replacing and lining several culverts, adding lighting at two county road intersections, and lengthening the right turn lane at Nicollet County Road 13.

The Mathiowetz Construction Co. of Sleepy Eye was awarded the project with a bid of $4,988,902.63
