Live discussion: Is it Carmageddon II or Carmaheaven?
The 405 Freeway closure known as "Carmageddon II" is in full swing, as crews work to demolish the northern half of the Mulholland Drive bridge as part of a $1-billion project that includes adding a carpool lane to the freeway below.
Times' reporter Matt Stevens will join city editor Shelby Grad for an update on the status of this second closure of 10 miles of the 405 Freeway at 1 p.m. PST.
So far, the closure of one of the nation's busiest freeways appears to be going off without a hitch. Demolishing and rebuilding the bridge is part of a $1-billion freeway improvement project that includes adding a 10-mile northbound carpool lane through the Sepulveda Pass.
Early Saturday, crews will dump 1,200 cubic yards of dirt underneath the 80-foot-tall Mulholland Drive bridge so that falling debris does not damage the freeway roadbed below.
The next steps over the weekend include using jackhammers to ram and punch through the top of the bridge in a process called "slotting," while other jackhammers will be used to chip away at girders underneath the bridge. Concrete must be removed from both the center and outer spans of the bridge, officials said.
Transportation officials are encouraging residents to "avoid the area, or eat, shop and play locally."
