Construction from W. Nicollet to N. Mankato 2015-16

Hwy 14 detour Aug. 10 to mid-October

The four-lane expansion from west of Nicollet to North Mankato is underway. Nicollet County Road 23 south of Hwy 14 is closed until late summer 2016. The bulk of the work in 2015 will be utility relocations, erosion control, bridge fills for the new interchange and general grading operations along existing Hwy 14 for the additional two lanes. In addition culverts will be replaced resulting in an 8 week detour of Hwy 14. The project is expected to be complete in the fall of 2016.
