Improvements include constructing a new southbound on-ramp from northbound Crenshaw Boulevard and increasing storage space for vehicles on Interstate I-405 on and off-ramps and local streets by widening the road resulting in congestion mitigation. improving traffic operations of the I-405 between Western Avenue, Post Mile (PM) 14.3 and Crenshaw Boulevard, PM 15.8 and at the Crenshaw Boulevard interchange.
Currently Construction is ongoing Monday through Friday 7 a.m. to 5 p.m. with a reduced speed limit of 55 mph through the work zone.
