The NB I-5 off-ramp at Imperial Highway will be permanently closed starting this Sunday. Here’s the press release from Caltrans:
Caltrans will permanently close the northbound Santa Ana Freeway (Interstate 5) off-ramp at Imperial Highway on Sunday, September 8 at 11:59 p.m. Northbound I-5 motorists will have access to the Norwalk Boulevard, Rosecrans Avenue and Florence Avenue off-ramps.
The closure will allow construction to continue for the new southbound I-5 off-ramp at Imperial Highway and other structural work. The on-going construction is part of the $1.6 billion I-5 South Corridor Improvement Projects to widen the freeway by adding one general purpose lane and one High Occupancy Vehicle (HOV) or carpool lane, in both directions from the Los Angeles County/Orange County line to I-605.

The work involves drilling in the center median on Imperial Highway for large (80-inch diameter and 100-feet deep) Cast in Drill Hole (CIDH) foundations for the new Imperial Highway off-ramp bridge. The CIDH work includes drilling, excavating earth, setting rebar and pouring concrete. For the safety of the public and for work crews, full street closures are necessary during this work at this location.
