The extreme fluctuation of temperatures dipping above and below freezing the past few weeks has created prime conditions for potholes on Indiana interstates, U.S. routes and state highways. Where possible, crews will limit their daytime work hours and try to avoid working in travel lanes during peak times.  However, motorists might encounter maintenance crews making priority repairs any time, day or night. To report a pothole on a numbered state route, interstate or U.S. highway, contact your regional INDOT district or follow the “Report a Concern” link at or on the INDOT mobile app. For potholes on city streets or county roads, please contact the proper city or county maintenance department.
