The Summit Police Department will be conducting a Roadside Safety Checkpoint on Friday July 10, 2020. The checkpoint will be in the 5600 blk. of S. Harlem Ave. in the southbound lanes and will operate from 11 p.m. to 4 a.m. Operating checkpoints throughout the year helps us achieve the goal of informing thousands of motorists of the dangers of impaired driving. The police detail is being paid for by a grant from the Illinois Department of Transportation (I.D.O.T.). As partners with I.D.O.T. the Summit Police Department is focused on improving the safety of our roadways through education and enforcement.
