Monticello, IN – Drivers in Carroll County should prepare for a significant traffic detour as U.S. 421/State Road 39 is scheduled to close for maintenance beginning Tuesday, September 2.
According to the Indiana Department of Transportation (INDOT), the closure will take place between County Road 1200 W and County Road 1100 N. The work, which involves small structure maintenance and repairs, is expected to last for approximately three weeks.
INDOT officials confirmed that the official detour route will direct motorists onto State Road 18, I-65, U.S. 231, and U.S. 24/U.S. 421. Drivers are urged to allow extra travel time and use caution when navigating alternate routes.
The project is part of INDOT’s seasonal maintenance plan aimed at improving road safety and infrastructure reliability. Local access for residents and businesses within the closure area will be maintained where possible, though through traffic will be prohibited.
Commuters traveling between Monticello and points south along U.S. 421/S.R. 39 are advised to plan ahead to avoid delays.
