The Project undertakes major additions and changes to the existing roadway system by adding express lanes, improving existing roadways, enhancing safety, adding capacity and mobility, and accommodating future light rail. The new bridge will be over 15,000 ft long, with 143-ft spans matching the pier locations of the 1990’s bridge, enhancing boater safety and aesthetics of the bridge structures. BCC’s Traffic Engineering Operations Department provided design and construction support service for Signing and Pavement Markings, Lighting and ITS. Project signing includes new overhead sign structures to guide motorists through tolled express lanes and non-tolled I-275.
The lighting system includes roadway and shared-use path lighting along the causeway and bridge section, aesthetic lighting on the primary and secondary aesthetic features of the Sails, and the navigation channel signal lighting. Also the lighting for the District 7 ITS Sunguide RTMC control room was provided.
ITS systems include bridge mounted ITS devices, express lane DMS signs, general use DMS, CCTV incident monitoring, MVDS detection systems, emergency access gates, generator backed power systems, redundant fiber backbone, weather monitoring systems, wrong way detection, and wet pavement warning systems.
