SACRAMENTO -- The California High-Speed Rail Authority has approved re-evaluating the Interstate 5 corridor over the Grapevine and Tejon Pass as a potential route for high-speed trains from the San Joaquin Valley to the Los Angeles Basin.


On a 9-0 vote today, the board gave a green light to a "conceptual study" that is expected to cost about $700,000 and take three to six months. Engineers hope to learn if the Grapevine is a reasonable alternative to include in a detailed environmental analysis.


The Grapevine was rejected as an option after a 2005 environmental analysis of the entire length of the proposed statewide, 800-mile high-speed train system between Los Angeles and San Francisco, with connections to Sacramento and San Diego. The rejection was based on the expected complexity of construction to deal with mountain grades over the Tehachapi Mountains and concerns over earthquake faultlines in the mountain range.

As a result of that 2005 study, the authority has focused its more detailed analyses on two options that head from Bakersfield, southeast through the Tehachapi Pass to Lancaster and Palmdale before swinging into Los Angeles.
