Ludlow Street from Route 6 to Penn’a Avenue. Speed limit is 25 MPH and is enforced by police hiding at the side of the street. Speed limit on the four-lane is 50 MPH. Many drivers leave the highway and do not think about the lower limit on the city street. Penn’a Avenue speed limit is 35 MPH so many drivers also turn from that street to Ludlow Street without realizing the slower limit on Ludlow Street. Be VERY careful on Ludlow Street.
