Hwy 14 Nicollet to N. Mankato detoured beginning July 25 (Weather Permitting)
Detour expected for 3 months

Weather permitting, Hwy 14 motorists from Nicollet to North Mankato are advised to prepare for a three-month detour beginning Monday, July 25 to build the connections between existing Hwy 14 and the new alignment south of Nicollet.

Hwy 14 detour consists of Nicollet County Roads 25 and 23.  Expect added stops at county road intersections.  As with any changes in routes and travel conditions, we advise added caution.

Hwy 111/County Road 23 (south of the new interchange) will be detoured to County Roads 25, 17 and Hwy 99. 

The duration of the detour has been increased from 2 to 3 months to assist construction that has been slowed by numerous rains.

This is the second year of construction on the expansion project.  This year work includes installing granular and aggregate bases then concrete paving, striping, signing, and erosion control.  The bridge for the new interchange was completed ahead of schedule, but rain after rain has slowed the earthwork by several weeks. The project is expected to be complete in November.
