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

into Arizona
.
The maximum speed limit for the entire California segment of Interstate 40 is 70 mi/h.

History
The segment of I-40 in California was approved as a chargeable Interstate on July 7, 1947. 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. 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
