Ongoing Roadway Improvements 

SANDAG is conducting a series of roadway closures to replace the existing toll system equipment with new state-of-the-art technology. Work includes extended, full and partial closures of the Toll Road lanes and on- and off-ramps along the roadway. To minimize the impact for drivers, extended closures will be isolated and not simultaneous. Signs will be in place in advance of upcoming closures and provide detour routes for motorists to reach their destination. Drivers are encouraged to slow down and give themselves more time to follow signs for alternate routes while the closures are in place. This project is expected to be completed in late 2022.
