A news conference just wrapped up at the city of Los Angeles’ Emergency Operations Center about the upcoming 405 closure over the Sepulveda Pass this weekend for the partial demolition of the Mulholland Bridge.
Among the points made at the news conference:
•Los Angeles Mayor Antonio Villaraigosa asked the public to not drive, particularly in the areas expected to be most impacted by the closure. “It’s really going to depend upon you,” he said. “Do not get into the car and add to the traffic.”
“We can either say we survived Carmageddon or we survived the Carmageddon hype,” he added.
•The Metro Red and Purple Line subways, the Orange Line and 26 Metro bus lines are free this weekend. See this earlier post for more details.
•I don’t think there has been a planning effort of this magnitude since the Olympic games and I think it’s going to show this weekend,” said Supervisor Zev Yaroslavsky, whose district includes the Sepulveda Pass.
As many of you are surely aware, there’s been several homemade videos floating around the web about Carmageddon. Here’s one that is G rated — as in “government website appropriate” — and is quite funny.
When the I-405 Countdown to Closure clock rolls into zero at midnight on July 16, the by-now onerous warning will morph into high-definition images streamed live from metro.net for a world-wide view of the demolition work on the Mulholland Bridge during Carmageddon weekend.
The countdown clock, a web widget downloadable in various sizes from metro.net, went viral in June when anticipation for the world’s largest traffic jam jumped the shark. By July 1, web counters had clocked 1,173,792 views of the media assets page. What’s more, the counters have been embedded in at least 100 local sites, not including this page (at right). All such widgets will morph into the live stream when their counters reach zero.
Metro issued a long news release this afternoon explaining the process in which the Mulholland Bridge will be partially demolished this weekend when the 405 is shut down over the Sepulveda Pass.
The entire release is below. Here are a few highlights:
•This is not an “implosion” type demolition. Half the bridge will be taken down by machines — giant jack hammers — nibbling away at the structure.
•About 4,000 tons of concrete are expected to be removed from the southern half of the bridge. While the southern half is rebuilt, the northern half of the current bridge will remain open to traffic. The northern half will be demolished in a similar exercise next year.
•The release says this is the first time in half a century that the 405 in this corridor will be completely shut down.
•The current Mulholland bridge is currently 72 feet wide, 579 feet long and 80 feet high (60 feet from the bottom of the bridge to the 405 roadbed). The new bridge will be widened by 82 feet wide and 608 feet long. The placement of the new columns will allow the new freeway lane — a carpool lane — to be built on the northbound side of the 405.
Here’s the entire news release:
Bridge Demolition Work Will be a Meticulous, Painstaking Process, not a Vegas-Style Demo
Contractors for the I-405 Sepulveda Pass Improvements Project are planning a precise, carefully orchestrated ballet of workers and machinery to demolish half of the Mulholland Bridge the weekend of July 16-17, not a Vegas-style demolition.
The iconic three-span box girder bridge, standing tall between the canyon vistas connecting San Fernando Valley suburbs with urban Los Angeles’ Westside for more than 50 years will see its southern side steadily chipped away over 53 hours, not 53 seconds. The demolition will be accomplished utilizing the relentless “tat-tat-tat” of jack hammers mounted on heavy equipment, not dynamite.
