405

Magnolia Street, which straddles Huntington Beach, Fountain Valley and Westminster, to remain open to traffic during construction, minimizing impacts to the community.

Four other bridges on the project have also been completed. Slater Avenue in Fountain Valley was the first bridge to open in 2019. Last year, Bushard Street in Fountain Valley and McFadden Avenue, which links Huntington Beach and Westminster, were completed. Last month, Talbert Avenue in Fountain Valley opened.

In addition to the bridge construction, substantial work to improve on- and off-ramps, widen the freeway, and replace soundwalls has been completed. As a result, overall construction on the project that began in early 2018 is approximately 55 percent complete.

Next month, the Warner Avenue bridge in Fountain Valley is expected to fully close to traffic for reconstruction. Demolition of the overcrossing will require overnight closures of I-405 near the bridge. For the latest updates, visit the project’s interactive map at octa.net/405map.
