San Diego’s transportation agency announced an alternate traffic route for northbound commuters on State Route 125 through September amid ongoing construction. 

Dedicated FasTrak-only lanes will be temporarily closed adjacent to the toll booths north of Otay Mesa Road,  according to the San Diego Association of Governments (SANDAG). The alternate traffic routes will begin Sept.6 at 8 a.m. through the end of the month. 

The changes accommodate the installation and testing of new overhead rolling equipment in dedicated FasTrack traffic lanes. According to the agency, the new tolling equipment is part of a broader effort to make technology enhancements along the SR 125 Toll Road and Interstate 15 Express Lanes.
One lane will be dedicated exclusively for FasTrak through traffic, and two lanes available for cash/credit toll road customers.

The agency began upgrading the tolling equipment on SR 125 in late 2021 and is anticipated to be completed by the end of 2022. Installation of new roadway equipment on the I-15 Express Lanes was completed in 2021.

Alternative route signage will be in place to guide FasTrak customers through toll booth lanes. If work progresses ahead of schedule, the FasTrak-only lanes will reopen early.
