The Mulholland Bridge over the 405 Freeway in the Sepulveda Pass reopened Wednesday morning. The two phase-demolition of the bridge was the cause behind the first "Carmageddon" in 2011. The second phase was in 2012.

"This bridge is important to the Santa Monica mountain communities — gets approximately 20,000 vehicles a day [crossing] over the bridge, and so returning it [to] full capacity is a much needed mobility improvement," Metro spokesman Dave Sotero told KPCC.

Crews gave the bridge a seismic-upgrade, widened the center median and added sidewalks.

County and state transportation officials say the Mulholland Bridge over I-405 in the Sepulveda Pass opened for crossing at 6 a.m. Wednesday. A ceremony celebrating the opening is planned for later in the day.

Construction on half of the bridge brought the weekend-long shutdown of a 10-mile stretch of the notoriously congested west-side freeway in the summer of 2011. The shutdown was dubbed "Carmageddon" in advance by officials warning drivers of possibly unprecedented gridlock, but motorists mostly stayed away and the project was finished quickly without major problems.

A year later a similar shutdown occurred for the other half of the bridge that spans I-405, with similar smooth results.
