Between Kildare and Pulaski on Diversey, there is a long stretch of road that crosses underneath the Metra tracks above. The speed limit, like most Chicago streets, is 30. Most exceed 45 or 50. There is a bike lane on the right, and if there are no bicycles, cars will pass slower-moving cars in the bike lane. Easy money for Chicago cops sitting nearby watching. I work adjacent to this stretch of road and have seen many cars be pulled over.
