Ortega Highway

By The Capistrano Dispatch

Interstate 5 underneath the Ortega Highway bridge will be closed for two evenings as construction crews from the California Department of Transportation begin major demolition work, as part of the I-5/Ortega Highway interchange improvement project.

Northbound and southbound I-5 lanes underneath the the bridge will be closed between 11 p.m. and 7 a.m. on Friday, August 2 and Saturday, August 3. Caltrans construction crews will be demolishing the southern half of the bridge. Most of the work is expected to be completed during those two nights, however, demolition activities may carry over to next weekend, if necessary.

Northbound and southbound I-5 traffic will be diverted to the Ortega Highway off-ramps and re-enter the freeway at the on-ramps. During construction, motorists from Ortega Highway can access the freeway at either Camino Capistrano or Junipero Serra Road.

Both sides of the Ortega Highway pedestrian walkway will be closed during construction but will reopen at 7 a.m.

Correction: A previous version of this story stated closures will begin Thursday. The closures begin Friday, August 2 at 11 p.m. until 7 a.m. and resume Saturday, August 3 at 11 p.m. until 7 a.m. To clarify, on- and off-ramps during construction will be used to reroute freeway traffic. To enter the freeway from Ortega Highway, use either Camino Capistrano or Junipero Serra Road.
