Carmageddon II: Smash and Dash

Construction crews have just 53 hours to demolish the north half of the Mulholland Drive bridge in the Sepulveda Pass over the 405 Freeway on Sept. 28-Oct 1. The southern side of the bridge, which was knocked down in July of last year during the first Carmageddon freeway closure, has since been replaced with a new bridge.

Preparation

Crews create access points throughout the top of the bridge to remove leftover wood forms from cavities.

Protecting the 405

Trucks deposit 1,200 cubic yards of dirt under the bridge to protect the freeway from falling debris.

Deconstruction

Four excavator-mounted jackhammers chip away at the concrete in the middle and move slowly outward.

Rebar

As the rams are working, technicians with cutting torches remove rebar for recycling.

Cleanup

Front-end loaders place dirt and concrete into trucks for transport to a nearby storage site.
