The Sunnyvale Town Council on Jan. 13 approved a $497,200 engineering contract with Kimley‑Horn and Associates to design repairs and upgrades for traffic signals on the town’s segment of Belt Line Road and to prepare bidding and construction-phase services.

Matt (Town Engineer) told the council the Belt Line segment inside Sunnyvale currently carries about 31,000 vehicles per day and has two signals that are not coordinated; a third signal will be added to serve the Gateway/Tom Thumb development. The Kimley‑Horn scope includes upgrading existing controllers, installing optic-fiber conduit and cable from Tripp Road to Towne East Boulevard, and making intersections compliant with new PROWAG (Public Right‑of‑Way Accessibility Guidelines) pedestrian requirements.

The design will also include uninterrupted power supplies sized for roughly four hours of temporary operation, revised left‑turn storage and a right‑turn bay adjacent to the new convenience store planned at Towne East and Belt Line. Staff said the fiber communications and camera-based video detection will enable corridor coordination and provide video feeds useful to public safety.

The project will be packaged into three bid contracts: signal equipment and upgrades, optic‑fiber construction and a paving contract for turn-bay and ramp work. Staff reported ongoing coordination with the City of Mesquite and said Mesquite has indicated a willingness to accept maintenance responsibility for the upgraded intersections under a modified interlocal agreement; staff expects to present an interlocal for council consideration later.

Council member Eldridge moved to approve the contract; the motion passed unanimously by members present.

Kimley‑Horn’s contract will proceed to design; staff said construction timing will depend on development schedules and coordination with Mesquite and with the Gateway developer.
