Imperial Highway & Pioneer Blvd. Project – Week of Mar. 16 – Mar. 22, 2018

Construction on this project is 79% complete.

Upcoming changes:

    • Imperial Highway is scheduled to be closed from Adore Ave. to the Frontage Rd. on the night of Tuesday, Mar.20 from 8:00 p.m. to 6 a.m. to allow a concrete pour on the top side of the Imperial Highway Bridge. The Imperial Highway off ramp from southbound I-5 will remain open, but traffic will only be able to turn right or to go straight. Detour map below:


  • Norwalk Blvd. / San Antonio Dr. is tentatively scheduled to be closed between Adore St. and Olive St. on the nights of Tuesday, Apr. 3, Wednesday, Apr. 4, and possibly Thursday, Apr. 5 from 8 p.m. to 6 a.m. to allow installation of girders across the second half of the San Antonio Bridge.(Detour map below).
  • This will also require the closure of up to two lanes on northbound I-5 from Silverbow Ave. to Pioneer Ave. and the northbound Norwalk Blvd. off ramp.
  • .

The top of the Imperial Highway Bridge almost ready for concrete pour (below):


I-5 from Silverbow Ave. north all the way up to Pioneer Blvd. is in varying stages of progress with crews spreading base (gravel), grading, compacting and paving. This activity includes compaction with a vibratory roller, so residents in the nearby neighborhoods may experience noise and vibration during the day. This past week crews have been paving lanes between the Imperial Highway Bridge and the Pioneer Blvd. Bridge (below):



As crews work on Imperial Highway, Norwalk Boulevard and Pioneer Boulevard bridges at I-5, one lane in each direction may be closed on each street (at I-5) during the daytime, between 8:30 a.m. and 3:30 p.m.
