In the U.S. state of California, Interstate 40 (I-40) has its western terminus in Barstow. Known as the Needles Freeway, a major east–west route of the Interstate Highway System, it heads east from Barstow across the Mojave Desert in San Bernardino County past the Clipper Mountains to Needles, before it crosses into Arizona west of Kingman.

[edit] Route description

This route is part of the California Freeway and Expressway System[4] and is eligible for the State Scenic Highway System.[5] However, it is not a scenic highway as designated by Caltrans.[6] Interstate 40 from Interstate 15 to the Arizona State Line is known as the Needles Freeway, as named by Senate Concurrent Resolution 1 in 1968.[7] Interstate 40 goes through the Mojave Desert on its entire journey through California.

I-40 starts out at a junction with Interstate 15 in Barstow. The freeway passes through Marine Corps Logistics Base Barstow before leaving the city limits. I-40 provides access to the town of Daggett but passes south of the town. After passing south of the Barstow-Daggett Airport, I-40 goes through Newberry Springs and Ludlow before traveling along the south end of Mojave National Preserve. Several miles east of the preserve, I-40 intersects US 95 and the two highways run concurrently into the city of Needles. In Needles, US 95 continues south while I-40 continues east through Mojave Regional Park and across the Colorado River into Arizona.[8]

The maximum speed limit for the entire California segment of Interstate 40 is 70 mph (110 km/h).

[edit] History

The segment of I-40 in California was approved as a chargeable Interstate on July 7, 1947.[1] 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.[2] However, this was rejected, and eventually U.S. 40 was decommissioned in favor of Interstate 80.

Today, the Needles Freeway replaced what used 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.[9]

A sign in California showing the distance to Wilmington, North Carolina has been stolen several times.[10]

[edit] Future

The State of California submitted the segment of what is now State Route 58 between Barstow and Bakersfield for chargeable Interstate approval twice, in 1956 and 1968, presumably as an extension of Interstate 40, but it was rejected both times.[1] As a result of these rejections, this segment of SR 58 is being upgraded to freeway standards piece-by-piece as Caltrans has funds available. However, there is no current push to apply for Interstate designation.
