'''Interstate&nbsp;10''' ('''I-10''') is the southernmost transcontinental highway in the [[Interstate Highway System]] of the United States. It is the fourth-longest Interstate in the country at {{convert|2460.34|mi|km}}, following [[Interstate 90|I-90]], [[Interstate 80|I-80]], and [[Interstate 40|I-40]]. It was part of the originally planned Interstate Highway network that was laid out in 1956, and its last section was completed in 1990.

I-10 stretches from the [[Pacific Ocean]] at [[California State Route 1|State Route&nbsp;1]] (SR&nbsp;1, Pacific Coast Highway) in [[Santa Monica, California]], to [[Interstate 95|I-95]] in [[Jacksonville, Florida]]. Other major cities connected by I-10 include (from west to east) [[Los Angeles]], [[Phoenix, Arizona|Phoenix]], [[Las Cruces, New Mexico|Las Cruces]], [[El Paso, Texas|El Paso]], [[San Antonio]], [[Houston]], [[Baton Rouge, Louisiana|Baton Rouge]], [[New Orleans]], [[Gulfport, Mississippi|Gulfport]], [[Mobile, Alabama|Mobile]], [[Pensacola, Florida|Pensacola]], and [[Tallahassee, Florida|Tallahassee]]. Over one-third of its total length is within the state of [[Texas]], where the freeway spans the state at its widest breadth.
