Buffalo, Illinois Speed Traps
AM rush hour
Westbound, on the bridge above Milwaukee Ave, after Riverwalk exit but before the construction area. Usually there are 3-5 cruisers sitting in the median. After the first cruiser caught the first vehicle, other cruisers would wait for other speeders to "ignore" the first one and then catch the speeders.
PM rush hour
Sometimes there are cruisers hidding behind the temporary construction building. Not sure whether the cop tries to catch westbound or eastbound.
