Charles River Rd. Parkway near Bay Street
This ex-MDC (now DCR) parkway had is speed limit and signage installed in 1969 by decree. For a 3/4 mi. stretch from Watertown Square there are no signs confirming the unrealistic 30 MPH speed limit. Watertown PD officers harvest this road like a $100 toll road. Better than 50% of the time I have driven down this road there is a speed trap. Stay away from this parkway if you can.
