The Michigan Department of Transportation has a “Report a Pothole” program people can use to notify the agency of potholes on state roads. The toll-free phone line took in 215 calls in 2016. From Jan. 1 to April 10, 2017, it received 299 calls. According to a state news release in February, unseasonably warm temperatures this winter made roads vulnerable to potholes. People can either call 888-296-4546 or fill out a form on the website.
