July 16, 2011 | 10:27 am

Metropolitan Transportation Authority authorities are documenting each step in this "Carmageddon" weekend's partial demolition of the Mulholland Drive bridge.

A solar-powered digital camera at the site is snapping images every 15 seconds. High-definition images will be averaged together to allow Metro to provide a full time-lapse video of the project.

For now, a new image from the field is made available every 30 seconds and can be viewed above.

Officials at the construction site said earlier that work was running smoothly.

“It’s an impressive start to the work,” said Dave Sotero, spokesman for the Los Angeles County Metropolitan Transportation Authority.

Click for details about the demolition About 4,000 tons of concrete must be removed by early Monday morning as the south side of the bridge is torn down. The work is part of a $1-billion widening of the 405 Freeway that required the replacement of the 50-year-old bridge to make way for an HOV lane.

A 10-mile stretch of the key connector between the Westside and San Fernando Valley was shut down fully by midnight Friday and is scheduled to be ready for commuters by 6 a.m. Monday. Officials have said that if all goes well there's a chance the freeway could be open earlier.

ALthough roads so far have been notably trouble-free, emergency services officials have cautioned Angelenos not to get complacent about potential traffic jams.
