At 5 a.m. Wednesday, May 23 the new Imperial Highway on ramp to northbound I-5 opened to the driving public. The on ramp is only accessible from westbound Imperial Highway for the first few months. Eastbound traffic on Imperial Highway is directed by signage to use northbound Firestone Blvd. to northbound I-605 to northbound I-5. (Photos below):



At 9 p.m. Tuesday, May 22, the Pioneer Blvd. on ramp to northbound I-5 closed permanently. Signs are in place to direct northbound and southbound traffic on Pioneer Blvd. over to Firestone Blvd. to northbound I-605 to northbound I-5 as the alternate route. This area will be used  to construct two additional lanes on northbound I-5. Within the next few weeks, pile driving will begin here and it will last several weeks. Local residents should be aware of loud construction noise during the hours of 6 a.m. to 4 p.m. (Photo below):

This “crusher” recycles concrete debris from the demolition of the old freeway structures by crushing it into small pieces of aggregate and using it to back-fill and as the base layer of new concrete roadway (below):

Workers pour and level concrete for the “approach slab” at the south end of the Imperial Highway Bridge May 23 (below. The approach slab provides support for a smoother transition from the mainline lanes onto the bridge:

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.

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.
