Ramps along the 10-mile closure area of the 405 Freeway between the 10 and 101 freeways will begin to be shut down for “Carmageddon II” as early as 7 p.m. tonight and closure of individual freeway lanes will begin at 10 p.m. to ensure full freeway closure by midnight.
The closure is scheduled to continue until 5 a.m. Monday morning, Oct. 1.
Ramps and connectors will be reopened by 6 a.m.
During this closure, the Mulholland Bridge, 405 Freeway, and access ramps will be closed.
As with the previous 405 closure, Sepulveda Boulevard is intended as an alternate route for local resident access only.
Sepulveda Boulevard does not have the capacity to accommodate both local and diverted freeway traffic.
Motorists should instead use alternate regional freeway routes to completely bypass the area.
These include the 5, 15, 23, 55, 57, 101, 118, 126, 210, 605 and 710 freeways.
This time, the contractor is unlikely to complete the work early because it has more demolition work to perform within the same 53-hour period.
Two sets of bridge columns, rather than one the previous year, must now be removed. Demolition work will also be more complicated due to the presence of inactive utility lines not present in the previous bridge demolition work.
The demolition and reconstruction of the Mulholland Bridge is required to widen the freeway as part of the I-405 Sepulveda Pass Improvements Project.
The $1 billion, 10-mile northbound carpool lane construction project is a joint effort between Metro and Caltrans, and is being constructed by Kiewit Infrastructure West Co.
It is scheduled for completion in 2013.
