Interstate 405 Sepulveda Pass Widening Project
Project Status Reports (Monthly and Quarterly)
August 2009? - May 2010
CALL NUMBER: TF200 .I584*
SUMMARY
The I-405 Sepulveda Pass Widening
Project will add a 10-mile HOV lane and improve supporting
infrastructure such as ramps, bridges and sound walls on the San Diego
Freeway (I-405); while widening lanes from the Santa Monica Freeway
(I-10) to Ventura Freeway (U.S. 101). This project will reduce
existing and forecasted traffic congestion on the I-405 and enhance
traffic operations by adding freeway capacity in an area that
experiences heavy congestion. In addition to these modifications,
the project will improve both existing and future mobility and enhance
safety throughout the corridor. Project benefits include a
decrease in commuter time, reduce air pollution, and promote
ridesharing. The I-405 Sepulveda Pass Widening Project features
include: [adding] a 10-mile HOV lane on the northbound I-405 between
the I-10 and US-101 freeways, [removing and replacing] the Skirball
Center, Sunset Blvd. and Mulholland Dr. Bridges, [realigning] 20 on and
off ramps, [widening] 20 existing overpasses and structures, [and
constructing] approximately 18 miles of retaining wall and sound wall.
