Los Angeles County Metropolitan Transportation Authority spokesman Dave Sotero says the demolition of the south lanes of the Mulholland Drive bridge will be a highly-choreographed process. The contractor will take down portions of the bridge a little at a time.
7 p.m.: Caltrans will gradually close the on-and off-ramps of the 405 in both directions between the 10 and the 101 freeways.
10 p.m.: Crews will close lanes on the 405.
Midnight: The 10-mile stretch will be completely shut down. That's when workers begin trucking in tons of dirt to cover the freeway beneath the bridge with a 4-foot-deep cushion.
2 a.m.: Crews start slicing the Mulholland bridge in half lengthwise with a huge, diamond-bladed saw.
5 a.m.: The real demolition begins when crews bring in four hoe rams (which are giant, jackhammer vehicles).
2 a.m.: Demolition of bridge should be complete. Debris and dirt from freeway will be removed.
5 a.m.: The lanes of the 405 will re-open.
6 a.m.: All the surrounding on- and off-ramps will re-open.
