possible tt comment on mon, jun 20, 2016 It's easy to stomp on the gas on I-475 west of the downtown split because that section of road is wide and smooth, and both northbound and southbound I-75 drivers go through annoying construction areas. And because that section of road near the ProMedica overpass has a slight upgrade and a curve, it's easy for a law officer to remain hidden until it's too late. The speed limit on west bound I-475 between the downtown split and the Talmadge Road exit is 60 mph, I think. http://toledotalk.com/cgi-bin/tt.pl/article/197158/15Nov2015/Hand_held_speed_cameras_gets_around_camera_ban
