Seal Beach Boulevard Bridge
Once work to reconstruct the Valley View Street bridge is complete this summer, crews will begin demolishing and reconstructing the west half of the Seal Beach Boulevard bridge over the I-405. Similar to the Valley View Street bridge, crews will reconstruct the Seal Beach Boulevard bridge one half at a time.
During the first stage of construction, Seal Beach Boulevard (over the I-405 freeway) will be reduced to one lane in either direction with a center median dedicated exclusively for emergency response access for approximately 11 months
