San Diego Freeway will be shut between I-605 and Seal Beach Boulevard
Dec. 5 2011
ORANGE – Construction crews will completely close the northbound San Diego Freeway (I-405) Saturday night, and continue nighttime closures for three to four weeks, weather permitting.
The closures are part of the Orange County Transportation Authority’s West County Connectors Project. All northbound I-405 lanes will be closed between the San Gabriel River Freeway (I-605) and Seal Beach Boulevard. Once construction on the northbound I-405 is complete, closures will be switched to the southbound I-405.
The nighttime northbound I-405 closure will begin Saturday, Dec. 10 and last several weeks. Work will take place between 11 p.m. and 5 a.m. Monday through Friday and between 11 p.m. and 7 a.m. Saturday and Sunday. It is estimated that work will finish on both sides of the I-405 freeway by the end of January.
Detour signs will be posted and the suggested route is as follows:
From the northbound I-405, exit Seal Beach Blvd., turn right and proceed north on Seal Beach Blvd. / Los Alamitos Blvd., turn left on Katella to access the northbound I-605 on-ramp
From the northbound I-405, exit Seal Beach Blvd., turn left and proceed south on Seal Beach Blvd., turn right on Westminster Avenue, turn right on Studebaker Rd. to access the northbound I-405 on-ramp
From the northbound I-405, exit Westminster Ave., turn left on Westminster Ave and proceed west, turn right on Studebaker Rd. to access the northbound I-405 on-ramp
From the northbound I-405, exit Westminster Ave., turn left on Westminster Ave. and proceed west, turn right on Seal Beach Blvd., continue north on Seal Beach Blvd. / Los Alamitos Blvd., turn left on Katella to access the northbound I-605 on-ramp
Freeway closures are necessary as part of the 7th Street Bridge reconstruction. Crews will be building falsework to support the bridge as it is being reassembled.
The $277 million West County Connectors project will improve traffic flow by directly connecting carpool lanes on I-405, I-605 and SR-22. In addition, a second carpool lane will be constructed on I-405 between SR-22 and I-605.
