Signals & Lighting

Our Dayton S&L team provides all aspects of new construction and installation of traffic signals, street lighting, high mast lighting, navigational lighting, fiber optic interconnect installations and smart highway ITS systems.

We offer 24/7 service for emergency and routine maintenance of signals and lighting, responding to requests including equipment malfunctions, vehicle accidents and storm damage. We maintain a full complement of test equipment, allowing us to troubleshoot and repair all serviceable items, including signal controllers, conflict monitors, CCTV cameras, DMS boards, UPS units and power supplies. Our well-stocked warehouse ensures access to the materials we need to respond to routine and emergency requests.

Our lighting services include aesthetic projects as well as LED conversion projects for signals and street lights.

We perform projects as both a prime and subcontractor, with a bonding capacity of up to $100 million. We provide complete project administration of traditional bid build and design-build projects.
