Highway 22 motorists in Mankato are advised to expect detours during the overnight hours beginning Tuesday, July 6 as contractors replace the pavement markings for the roundabouts at Madison Avenue (Blue Earth County Road 17) and Adams Street. Detours will be implemented Sunday through Thursday evenings, from 6:30 pm to 6:30 am, until July 15, weather permitting.

Northbound Highway 22 traffic will be detoured to Hoffman Road, Blue Earth County Road 12, Blue Earth County Road 17, Blue Earth County Road 56, and US 14.  Southbound Highway 22 traffic will be detoured to US 14, Blue Earth County Road 86, Blue Earth County Road 17, Blue Earth County Road 12, and Hoffman Road.

Madison Avenue traffic will be detoured to Raintree Road, Bassett Drive, and Carver Road.  Adams Street traffic will be detoured to Raintree Road, Bassett Drive, Carver Road, Madison Avenue, and Haefner Drive.

The project includes replacement of the striping and pavement messages at the two roundabouts which were constructed in 2013, as well as along US 169 in Saint Peter, from the south junction of Highway 22 to north of Chestnut Street.
