Residents Learn about Upcoming I-405 Bridge Work

In advance of traffic shifts on the Bolsa Chica and Goldenwest bridges as part of the I-405 Improvement Project, OCTA held a meeting for residents in Westminster on March 2. More than 30 people attended.

Weather permitting, crews will shift traffic by installing concrete barriers and restriping the Bolsa Avenue bridge in early March to create a work zone for demolition activities. The partial bridge demolition is scheduled for mid-March.

Construction on the Goldenwest bridge began in December and the remaining work on the traffic shift is also expected to occur in the coming weeks.

The demolition and reconstruction of both bridges are part of the I-405 Improvement Project, which adds a general-purpose lane and a tolled Express Lane facility in each direction of the 16-mile project. These bridges, two of 18 to be reconstructed as part of the project, will be partially closed for approximately 24 months. Learn more about the project here.
