Portions of the San Diego Freeway (405) will close down entirely along the Seal Beach, and Long Beach border tonight and Saturday morning.
Late night and morning commuters can expect significant delays while residents in the Rossmoor, Seal Beach and Long Beach areas should prepare for nighttime noise as crews work to remove the remaining columns and abutments for the old 405/22/7th Street connector.
Starting at 11 p.m., the northbound 405 will close entirely from Seal Beach Boulevard to the San Gabriel Freeway (605) until 7 a.m. Saturday.
On the southbound side of the 405, several lanes will close between the 605 and Seal Beach Boulevard, leaving just two lanes open.
To get around the complete northbound 405 closure, try exiting at Westminster Avenue, head west on Westminster Avenue and turn right on Seal Beach Boulevard and head to Katella Avenue to access the northbound 605 on ramp. To continue on the northbound 405, take Westminster Avenue to Studebaker Road, head north on Studebaker Road to the 405 north of Atherton Street.
The closures will cause major nighttime traffic delays along one of the nation's most heavily traveled freeways bordering Orange and Los Angeles counties and in the surrounding Seal Beach, Long Beach and Garden Grove neighborhoods. However, it is a necessary safety precaution as the 7th Street connector is torn down, said Orange County Transportation Authority officials. The work is part of the $277 million, three-year West County Connector Project.
