Interstate 10
Interstate 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 2,460.34 miles (3,959.53 km), following I-90, I-80, and 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 State Route 1 (SR 1, Pacific Coast Highway) in Santa Monica, California, to I-95 in Jacksonville, Florida. Other major cities connected by I-10 include (from west to east) Los Angeles, Phoenix, Tucson, Las Cruces, El Paso, San Antonio, Houston, Baton Rouge, New Orleans, Gulfport, Mobile, Pensacola, and Tallahassee. Over one-third of its total length is within the state of Texas, where the freeway spans the state at its widest breadth.
Between its west terminus in Santa Monica, California, and the major East Los Angeles Interchange, I-10 is known as the Santa Monica Freeway. The Santa Monica Freeway is also called the Rosa Parks Freeway, named after the civil rights activist, for the segment beginning at I-405 (San Diego Freeway), and ending at I-110/SR 110 (Harbor Freeway). The segment between the East Los Angeles Interchange, in East Los Angeles, and the city of San Bernardino, 63 miles (101 km) long, is called the San Bernardino Freeway.
Other names exist for I-10. For example, from 1976 to 2022, a sign near the western terminus of the highway in Santa Monica proclaimed the highway to be the Christopher Columbus Transcontinental Highway. The state legislature authorized its removal in 2022 after years of lobbying by Native Americans.
I-10 is known to a considerably lesser degree as the Veterans Memorial Highway, and it is listed as a Blue Star Memorial Highway. In Palm Springs, I-10 is also named the Sonny Bono Memorial Freeway, named after the singer, actor, and politician, as a tribute to the late entertainer who served both as the mayor of Palm Springs, and as a US Representative. Another stretch a short distance east in Indio is proclaimed the Doctor June McCarroll Memorial Freeway, named after the nurse known for popularizing road lane striping.
In Arizona, the highway is designated the Pearl Harbor Memorial Highway. The portion through Phoenix is named the Papago Freeway, and it is a vital piece of the metropolitan Phoenix freeway system. This designation starts at State Route 101 (SR 101; Loop 101), near 99th Avenue, and continues eastward to the interchange southeast of downtown, which is the terminus of I-17.
Near Buckeye, the freeway has milemarkers posted every 0.2 miles (0.32 km) from 112.2 to 110.8 with the Interstate shield and direction of travel posted on the westbound lanes. On the eastbound lanes, milemarkers from 110.8 to 112.2 do not include the I‑10 shield and direction of travel.
From the southern terminus of I-17 to the southernmost junction with SR 202 (Loop 202), the highway is signed as the Maricopa Freeway. This name holds true as well for I-17 from its southern terminus to the Durango Curve south of Buckeye Road. From Loop 202 south to the eastern terminus of I-8 just southeast of Casa Grande, the highway is declared the Pearl Harbor Memorial Highway. The Arizona Department of Transportation also has maps that show it as the Maricopa Freeway, while the American Automobile Association and other sources show it as the Pima Freeway. The latter's name is used on a stretch of Loop 101 from Loop 202 to I-17.
