I think there should be traffic lights at Oak Hill RD & Groton Rd in Westford, MA. The traffic there has increased in several year since the adding of the Rapid Refill gas station at the corner of Oak Hill & Groton RD. I also think the highway department of Westford or the state of Mass. should do a study of traffic flow near the Rapid Refill gas station. Traffic lights are needed there. I don't won't someone to wait until someone gets killed or badly hurt in a car accident  to say we need traffic lights there. Please propose this project. With the town of Westford growing. The town should do something soon. In the early 90's a elderly man was killed in an auto accident at the intersection of Tyngsboro Rd./ Depot Rd. at Groton Rd (Route 40). This accident prompted traffic lights be installed at the intersection. Again I don't want this repeated again near the Rapid Refill gas station.
