As you travel on Michigan Ave, that’s one of the main through streets, the street from the Dunkin Donuts/Post Office intersection going South towards Roselle Park, just a few blocks before you pass under the GS Pkwy overpass, there is a municipal park on the leFort Speed Limit is 25 MPH. Often cops hide in the park /playground driveway at night. Most drivers go over 35 unless you know about this one. Have seem them there for many years. Slow down on Michigan Ave, it’s 25mph.
