Acuity Brands Provides LED Solutions to Meet the Bay Bridge Tunnel’s Rigorous Demands

The California Department of Transportation decided to install LED lighting in the Yerba Buena Tunnel replacing VHO fluorescent fixtures installed in the tunnel 30 years earlier. The VHO fixtures required time-consuming maintenance every two years, necessitating the expensive closure of traffic lanes inside the tunnel with approximately 270,000 vehicles passing through the Yerba Buena Tunnel daily.

The challenge was to identify an LED luminaire that could provide high levels of visibility plus the reliability and long-term performance required of luminaires used in demanding tunnel environments.
