Chip seal work will close a section of State Road 331 between Bourbon and State Road 25 in Marshall County beginning on Monday.
Chip sealing helps preserve the existing road surface by protecting it from moisture, ultraviolet degradation, and other damaging exposures.
INDOT officials say the work will continue through Friday, June 16, but that timeline may adjust due to weather.
The official detour takes drivers traveling north on State Road 331 eastbound on State Road 25, north on State Road 19, west on U.S. 30 back to State Road 331. Drivers traveling south on State Road 331 will be detoured east on U.S. 30, south on State Road 19, west on State Road 25, back to State Road 331.
