Cambridge Road needs a DO NOT ENTER sign between the hours of 8am-5pm like Washington has. Cars are constantly speeding up our road to avoid the traffic at Baltimore Pike and Church. These cars are sometimes doing upwards of 45 mph or more. In addition, on several occassions my husband and I have been driving up Cambridge to pull into our alleyway at the top of the street and cars have pulled to the left of us, sometimes up onto the sidewalk, just to pass us because we are following the speed limit! We have many young, small children on our street and have had incidents before where children were hit. I don't want to see one killed because someone cannot be patient or follow the speed limit, something needs to be done!!
