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. This work requires 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.

Construction Notices

Alternate Traffic Route on Northbound SR 125 Toll Road: September 6-30

The alternate traffic route on the northbound SR 125 Toll Road will be in effect for FasTrak users from 8 a.m. on Tuesday, September 6 and extend throughout the month of September while FasTrak only bypass lanes are temporarily closed adjacent to the toll plaza north of Otay Mesa Road. All southbound traffic will be routed through the toll booth lanes to accommodate the installation and testing of new overhead tolling equipment in the FasTrak only lanes.

All toll booth lanes will be available for FasTrak customers during this time, with one lane dedicated exclusively for FasTrak through traffic and two lanes available for cash/credit toll road customers. 

What to Expect During Construction 

Travelers, businesses, and nearby residents can expect intermittent noise and lights as SANDAG completes this work. All reasonable steps will be taken to minimize impacts to nearby residents, businesses, and travelers. We appreciate your patience during this major roadway improvement!
