Construction Updates

The Orange County Transportation Authority (OCTA), in coordination with Metrolink, is taking emergency action to stabilize the rail line in north San Clemente.

Construction Activities

Contractors will begin mobilizing equipment to begin construction of a 1,400-foot-long catchment wall on the bluffs side of the tracks at Mariposa Point. The wall will extend from the El Portal Beach access point to Linda Lane. The wall, designed to complement the coastal landscape, will be a permanent structure.

Passenger rail service will not be impacted during construction.

Construction Schedule

Construction is expected to begin Monday, Sept. 15 and continue through summer 2026. Crews will work Monday through Saturday from 6 a.m. to 6 p.m. No nighttime work is anticipated.

Trail and Beach Access

The San Clemente Pedestrian Beach Trail will be closed from the North Beach parking lot to El Portal during work hours but will reopen at the end of each workday and will be open on Sundays. The trail will be closed from El Portal to Linda Lane until project completion.

The Mariposa underpass will be closed. All other beach access points will remain open during construction. To ensure the safety of pedestrians, flaggers will be stationed at beach access points to assist with pedestrian crossing.

Staging Areas

Contractors will be staging equipment and materials primarily in the North Beach parking lot. Additional staging areas are still being identified.
