405 Freeway Update
The Orange County Transportation Authority, in cooperation with Caltrans, is widening the San Diego Freeway (I-405) between SR-73 and I-605.The project is improving 16 miles of I-405 between the SR-73 freeway in Costa Mesa and I-605 near the Los Angeles County line. Construction updates are as follows: Partial Lane Closures on Seal Beach Boulevard for Median Work Crews began median removal on Seal Beach Boulevard between Lampson Avenue and Old Ranch Parkway this week. This work will require lane reductions on Seal Beach Boulevard continuously for the duration of the work.
The center median will be demolished, removed and reconstructed to allow for the addition of a dual left turn lane from southbound Seal Beach Boulevard to the northbound I-405 on-ramp.
Activities include median removal, landscaping/tree removal, excavation, concrete work, backfilling, striping and street/median restoration.
Median work began March 29 and is expected to last for about a week. Daytime work hours are 7 a.m.-4 p.m. Nighttime work hours are 9 p.m.-6 a.m. Crews may mobilize equipment as early as 6 a.m.
This work may be loud.
