In the wake of three serious car accidents in recent months, one resulting in a death, four street lights and a “Slow Curve Ahead” sign will be installed on Winter Street. After considering several safety options – including the installation of rumble strips on the roadway – selectmen at a recent meeting authorized Town Administrator James Boudreau and Highway Director Paul Foulsham to move forward with the lights and sign. Boudreau said speed was a factor in the accidents, all of which occurred on a curved stretch of the road. “We paved the road in early October, and that has contributed to motorists speeding,” he said. “Also, there’s a long straight lead before the curve and people tend to pick up speed as they approach it.” Police are increasing traffic patrols on Winter Street, which runs from Main Street and into Scituate.
