Utility work will close a stretch of State Road 331 south of Mishawaka this week.

INDOT says NIPSCO crews will be doing work on a gas transmission line on 331 between Tyler Road and Old 331-US 20.

This will close that stretch of the highway on Wednesday, and will keep it closed through the middle of October.

Official detours will be posted involving US 20, US 31, US 30, and US 6.
