REMINDER! Partial Lane Closures on Seal Beach Boulevard for Median Work
Crews will install temporary traffic signals at Seal Beach Blvd. and Lampson Ave. and at Seal Beach Blvd. and the northbound (NB) I-405 freeway ramps/Old Ranch Parkway.

Activities include the installation of temporary wooden poles, traffic signal heads and electrical work.

Once temporary signals are in place, crews will begin work on new signal poles at these intersections.

Temporary traffic signal construction is anticipated to start as early as 10 p.m. Friday, April 9 for approximately two weeks on weeknights.

Seal Beach Blvd. and Lampson Ave. will be intermittently reduced to two lanes at the intersection for the duration of the work.

Nighttime work hours are 9 p.m. to 6 a.m.
