An intersection in Rock Island that has seen 51 accidents and four deaths over the past 15 years is under review by TDOT.A traffic study is currently taking place at the intersection of Sparta Highway and Rock Island Road to determine if a flashing traffic signal would help reduce accidents. The intersection is heavily traveled and serves as the main entrance to Rock Island State Park which has over 600,000 annual visitors.Rock Island Constable Jason Dodson has pushed for a flashing light there for years, but his efforts have been short on results. A double fatality at that intersection on Jan. 11 has served to provide new momentum for a flashing light there."I think it would help create greater awareness of the intersection," said Dodson.
