Interstate 40, a major east-west route of the Interstate Highway System, has its western terminus in Barstow, California, United States. Known as the Needles Freeway, it heads east from Barstow across the Mojave Desert in San Bernardino County to Needles, before it crosses into Arizona west of Kingman.

[edit] History
The segment of I-40 in California was approved as a chargeable Interstate on July 7, 1947.[2] In 1957, the California Department of Highways proposed that the route be renumbered to Interstate 30 instead because of the already existing U.S. Route 40 in the state.[3] However, this was rejected, and eventually U.S. 40 was decommissioned in favor of Interstate 80.
The State of California also submitted the segment of what is now California State Route 58 between Barstow and Bakersfield for chargeable Interstate approval twice, in 1956 and 1968, but it was rejected both times.[2]
Today, the Needles Freeway replaced what use to be Route 66 across the Mojave Desert. As a result, a number of communities along the former route like Amboy have become ghost towns.[4]
[edit] State law
Route 40 from Route 15 to the Arizona State Line is known as the Needles Freeway, as named by Senate Concurrent Resolution 1 in 1968.[5]
