After nearly two years of study, stop signs and no-parking signswere approved for a neighborhood where residents have felt unsafe because of traffic. Laina Julier,president of the Pleasant Circle Improvement Association,told a recent selectmen’s meeting that neighbors noticed vehicles weren’t stopping at intersections and were parking too close to the intersections. Children who played in the neighborhood were at risk because of speeding cars, Julier said. Town engineer James Donovanrecommended that the signs be approved by selectmen, who agreed to the change. The cost will be less than $1,000.
