Happy Fourth of July from the 55 Freeway Project Team! Enjoy the festivities and drive safe!

Construction activities and closures will resume on Monday, July 6.

Crews are expected to perform electrical work along northbound and southbound Newport Avenue between El Camino Real and Nisson Road, which will require nighttime lane closures from 9 p.m. to 5 a.m. tonight, Thursday, July 2. At least one lane will remain open in each direction at all times.

On Wednesday, July 8 beginning at 9 a.m., crews are scheduled to sweep along the outside shoulder in both directions of the 55 freeway between I-405 and I-5. Look out for a cleaner corridor!

OCTA, in cooperation with Caltrans, is improving 4 miles of SR-55 between I-405 and I-5. The project will improve traffic flow and reduce travel time by adding one regular lane and one carpool lane in each direction. Also, the project will add merge lanes between several interchanges and stripe carpool lanes for continuous access, augmenting safety on the freeway by making merging easier. These enhancements are expected to create a better, smoother driving experience for motorists.
