Typically, this sort of express lane will have fewer interchanges than the primary lanes, and many such roadways only provide onramps for inbound traffic, and offramps for outbound traffic.Ī typical five-lane arterial equipped with a center turn lane. Generally, traffic flows in one direction or another in such a configuration (or not at all) the carriageways are not "split" into two-lane roadways during non-rush periods. Many urban freeways have entirely separate carriageways (and connecting ramps) to hold reversible lanes (the reversible lanes in such a configuration are often referred to as "express lanes"). Prior to the installation of a movable median barrier in January 2015, they were demarcated by vertical yellow markers placed manually in sockets in the roadway. The two center lanes of the six-lane Golden Gate Bridge are reversible they are southbound during morning rush hour and northbound at evening rush hour. Other systems use retractable cones or bollards which are built into the road, or retractable fences which can divert traffic from a reversible ramp. In some systems, a concrete barrier is moved during low-traffic periods to switch a central lane from one side of the road to another some examples are the five-lane San Diego-Coronado Bay Bridge in San Diego, California, the seven-lane Alex Fraser Bridge on the Fraser River in Vancouver and the eight-lane Auckland Harbour Bridge across the Waitemata Harbour in Auckland, New Zealand. Some more recent implementations of reversible lanes use a movable barrier to establish a physical separation between allowed and disallowed lanes of travel. The presence of lane controls allows authorities to close or reverse lanes when unusual circumstances (such as construction or a traffic mishap) require use of fewer or more lanes to maintain orderly flow of traffic. Reversible lanes are also commonly found in tunnels and on bridges, and on the surrounding roadways – even where the lanes are not regularly reversed to handle normal changes in traffic flow. Typically, it is meant to improve traffic flow during rush hours, by having overhead traffic lights and lighted street signs notifying drivers which lanes are open or closed to driving or turning. Together, the transponder system and the video system provide 99% operational accuracy and reliability for transactions.The south end of Lions Gate Bridge in Vancouver, British ColumbiaĪ reversible lane ( British English: tidal flow) is a lane in which traffic may travel in either direction, depending on certain conditions. The REL system employs an overhead gantry with 18 transponder readers and 24 high-speed cameras. The REL video toll option ensures access to all users. The REL was the first transportation project in Florida to employ totally cashless, all electronic toll collection. ![]() It is an innovative project that has won approximately two dozen awards of recognition by local, state, national and international organizations. ![]() The REL provides a direct connection between Brandon and downtown Tampa, allowing for express travel of people in cars and buses. The REL provides quality service with an aesthetically pleasing structure and reduced impacts to the community and the environment. To minimize the footprint of the expressway, most of the project was constructed as a concrete segmental bridge using only 6 feet of space within the existing median. Like many urban areas, purchasing the additional land needed along this corridor for typical highway widening was neither physically nor financially feasible. ![]() This is the first road to address urban congestion by combining the innovations of concrete segmental bridges, reversible express lanes and all electronic tolling. The Reversible Express Lanes (REL) is a First-of-its-Kind facility.
