(HURON COUNTY) -- Michigan Department of Transportation crews are removing existing traffic signals in Huron County to improve intersection operations. The changes are a result of a 14-month study to help MDOT identify unnecessary signals. The traffic light at M-142 (Michigan Avenue) and M-142 (Main Street) in Pigeon, M-25 (Main Street) at Michigan Street in Caseville, the M-53/M-142 (Van Dyke/Port Crescent Street) at Watkins Place light in Bad Axe, and the M-25 (Spring Street) at M-25/M-53 (Lake Street) in Port Austin will be removed. Two signals will be removed and replaced with an overhead flashing light on M-142 at Main Street in Elkton and on M-53/M-142 at Irwin Street in Bad Axe. Motorists may see short delays while the signals are removed. Work should be done by May. MDOT says additional improvements will be made in spring 2014.
