During freeway closures,Â Sepulveda BoulevardÂ will remain open and can be used as a primary detour route. Emergency vehicle access will be maintained at all times.
SkirballÂ BridgeÂ demolition and reconstruction will be conducted in two separate phases. The north side of the bridge will be demolished first. That will be followed by approximately seven months of north side bridge reconstruction. Upon completion of the north side of the bridge, the south side of the bridge will be demolished and rebuilt in the same manner.
Construction work is being coordinated with Caltrans and City ofÂ Los AngelesÂ to minimize traffic impacts as much as possible.
When completed, the seismically enhancedÂ SkirballÂ Bridgeâ€™s columns will be repositioned to accommodate the additional freeway lane created by the project.
TheÂ SkirballÂ BridgeÂ is the second of three major bridges to be rebuilt as part of the three and a half-year construction project. One-half of theÂ SunsetÂ BridgeÂ was demolished in late July.Â MulhollandBridgeÂ work is now scheduled to begin in early 2011.
As a design-build project, construction schedules are dynamic and subject to change. The latest construction updates will be made available on the project web site and on Twitter attwitter.com/I_405.
The $1 billion project, a joint partnership between the Los Angeles County Metropolitan Transportation Authority (Metro) and Caltrans, will create a 10-mile carpool lane on the northbound I-405 between I-10 and U.S. 101 Freeways. The project will add capacity to one of the busiest freeways in the region and make it safer. Other project enhancements include the improvement of supporting freeway infrastructure such as ramps and sound walls.
