Signal work begins next week at most of the intersections along FM 1709 (Southlake Boulevard). Advanced warning signs are going up along the road between State Highway 114 and Interstate 35W. Contractors will be upgrading communication and video cameras at signalized intersections. The project is expected to take four months. Traffic signals on FM 1709 are owned and operated by TxDOT.
