Northbound 605 Drops To One Lane For Paving Work In Whittier

Caltrans begins a series of overnight lane reductions and ramp closures on the northbound San Gabriel River (605) Freeway in Whittier on Friday. The paving work affects traffic between Beverly Boulevard and Rose Hills Road. Caltrans spokesman Marc Bischoff confirmed that the project will not require full freeway closures.

Drivers should expect reduced capacity from 7 p.m. Friday through 6 a.m. Monday. The northbound lanes will drop to one lane from 10 p.m. Friday to 4 a.m. Saturday. Traffic will expand to two lanes from 4 a.m. Saturday until 11 p.m. Sunday. The freeway will narrow back to one lane from 11 p.m. Sunday to 5 a.m. Monday. All northbound lanes will reopen by 5 a.m. Monday.

Ramp closures begin earlier than the mainline restrictions. The on-ramp from Beverly Boulevard to the northbound 605 will be closed from 7 p.m. Friday to 6 a.m. Monday. The Rose Hills Road on-ramp and off-ramp will also be closed during that same period.

Crews will demolish old freeway lane concrete on Friday nights. Bischoff warned that residents and businesses in the area may experience noise, vibrations, and dust during the work. The project is part of the Super 605 freeway corridor initiative to rehabilitate the highway from Long Beach to the San Gabriel Valley.

Caltrans encourages motorists to use the Harbor (110), Long Beach (710), or Orange (57) freeways as alternatives. Additional 55-hour extended weekend lane reductions are scheduled through the end of 2026.
