Seal Beach Blvd. Bridge Reconstruction

Since September 2013, crews have been reconstructing the east-half of the Seal Beach Boulevard bridge; the west-half of the bridge was completed last fall, which is the portion motorists are driving on today. Construction activity on the Seal Beach Boulevard bridge is scheduled for completion within the next couple months. Below is a summary of the remaining construction activities crews will be performing before the final seven lane bridge (four lanes northbound, three lanes southbound) is open to drivers later this year.

Crews have removed the falsework from the east-half of the bridge and are now constructing the new approaches to the bridge where traffic will soon tie-in to the new structure. Crews recently performed a "closure pour" to connect the new east-half of the bridge with the west-half of the bridge. Over the next couple months, crews will grind pavement, pour asphalt, install drainage and electrical systems, stripe the roadway and realign freeway on-ramps and off-ramps. 

Upcoming Closures - Summer 2014

  • Long-Term Closure: The northbound I-405 loop on-ramp on Seal Beach Blvd. will be closed for approximately eight weeks beginning Friday, July 25, 2014. Crews must realign and reconstruct this on-ramp to tie-in with the new east-half of the Seal Beach Blvd. bridge.

  • 12-Hour Nighttime Closure: The southbound I-405 off-ramp on Seal Beach Blvd. will be closed for 12-hours on a weekend night in August (exact date / time TBD). Crews must realign and reconstruct portions of this off-ramp to tie-in with east-half of the Seal Beach Blvd. bridge.

East Half Demolition

Crews successfully demolished the east half of the Seal Beach Boulevard bridge during back-to-back nighttime closures in Sept. 2013. Exactly one year after the west half of the bridge was demolished, the east half of the bridge was taken down and phase two of reconstruction can officially began! Nightly closures of Seal Beach Boulevard as well as the northbound and southbound I-405 will continue nightly, as crews will begin pile driving and they prepare the foundation for the new east half of the bridge. Check out a few snapshots of the east half of the bridge before and after demolition!

Visit www.octa.net/WCCDetourMap for a full list of closures scheduled on the WCC project.

Please be advised, regularly schedule nighttime closures will continue as planned. Visit www.octa.net/WCCDetourMap for a full list of closures scheduled on the WCC project.


On September 15, 2013, the west-half of the Seal Beach Boulevard bridge opened to motorists. In order to restore traffic to two lanes in each direction, crews worked around the clock this weekend to restripe Seal Beach Boulevard and modify signal timing before unveiling the new lane configuration.

Check out a few facts about the new west-half of the bridge!

Phases

The Seal Beach Boulevard bridge over the I-405 freeway is being reconstructed one half at a time. Back in late summer 2012, the bridge was reduced to one lane in each direction, with a center median dedicated solely to emergency services vehicle. This configuration remained in place until the west half of the bridge was completed on Sunday, Sept. 15, 2013.

Now that the new half of the bridge is complete, crews have demolished and are reconstructing the east half of the bridge. The final bridge is anticipated to be complete in mid-2014 and will include four northbound lanes and three southbound lanes.
