I-405 Sepulveda Pass Improvements Project
Status Reports (Quarterly and Monthly)
June 2010 - September 2015
CALL NUMBER: TF200 .I584*
SUMMARY
The I-405 Sepulveda Pass
Improvements 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. This series continues
the Interstate 405 Sepulveda Pass Widening Project status reports series.
