Sepulveda Pass
The crossing experiences heavy traffic (over 330,000 cars a day[1]) on a regular basis, commonly experiencing major traffic slowdowns lasting hours.[2] I-405 was widened by LA Metro, the county's transportation authority.[4] Additionally, funding has been secured to construct an expansion to Los Angeles's public transportation system through the Sepulveda Pass in the form of a new subway line or monorail, but the plan has not yet been finalized.[5] The Sepulveda Pass on Interstate 405 begins just south of Ventura Boulevard in the San Fernando Valley, climbing to just south of Mulholland Drive, then descending to just north of Sunset Boulevard, where I-405 and Sepulveda Boulevard enter the Brentwood and Westwood areas of West Los Angeles.[6] Beginning with The Westland School in 1965, a number of other educational and cultural institutions have located in the vicinity of Sepulveda Pass, creating an "institutional corridor" as an exception to the Mulholland Scenic Parkway Specific Plan's general prohibition of such development along the crest of the mountains.
