Southbound I-405 / Eastbound SR-22 Connector

I-405 Reopens Following Successful Bridge Bash

The southbound San Diego Freeway (I-405) reopened to traffic on August 18, 2013 after being closed between the San Gabriel River Freeway (I-605) and Valley View Street in Westminster. The northbound I-405 freeway reopened to traffic at 3 p.m. on August 18. After closing the I-405 freeway at 9 p.m. on August 17, crews worked around the clock and were able to complete the bridge demolition and reopened the freeway hours earlier than the original 5 p.m. target.

The nearly 18-hour full freeway closure was necessary so crews could demolish the bridge linking the southbound I-405 to eastbound Garden Grove Freeway (SR-22) as part of the West County Connectors project. Construction of the new connector bridge was completed July 2013.

Approximately 70 workers used more than 50 pieces of equipment, including 10 excavators, to chip away at the bridge while the freeway surface below was protected with steel plates. The concrete from the bridge demolition will be recycled and used on other parts of the project.

Traffic on the I-405 near the border between Orange and Los Angeles counties averages approximately 370,000 vehicles each day, making it one of the busiest in the nation. Typical weekend in the area is 350,000 vehicles a day.

The WCC team would like to thank the traveling public as well as local residents and businesses for their patience and understanding, which greatly contributed to the success of this major construction milestone. In addition, we would like to thank the construction crews and teams from Atkinson Construction, Cleveland Wrecking Company, Caltrans and OCTA for completing this job safely and ahead of schedule. Check out the time lapse video of the bridge demolition - eight hours of work in less than two minutes!
