Interstate 10

Interstate 10, or I-10, is the southernmost east-west, coast-to-coast interstate highway in the United States. It stretches from California State Highway 1, (CA/SR-1), also known as the Pacific Coast Highway, in Santa Monica, California to Interstate 95 in Jacksonville, Florida.

Designations

Between its west terminus in Santa Monica, California and the East Los Angeles Interchange it is known as the Santa Monica Freeway. The segment between the East Los Angeles Interchange and the city of San Bernardino, California (53 miles, or 92 km long) is known as the San Bernardino Freeway. Other names exist for the freeway. For example, a sign near the western terminus of the highway announces it as "The Christopher Columbus Transcontinental Highway." It is known to a considerably lesser degree as the "Veteran's Memorial Highway" and is listed as a Blue Star Highway.

A stretch in Palm Springs is signed as the "Sonny Bono Memorial Freeway" as a tribute to the late entertainer who served both as mayor and as a United States Congressman. A second stretch a few miles east in Indio is signed as the "Doctor June McCarroll Memorial Freeway." As a nurse with the Southern Pacific Railroad in the 1920s, Dr. McCarroll was alarmed at the number of head-on traffic collisions on a nearby stretch of then-new U.S. Highway 99, today known as both California State Highway 111 and California State Highway 86 as well as Interstate 10 which replaced it between Indio and Los Angeles. She is credited with painting a white stripe down the middle of 99 near Coachella in order to separate the two lanes of traffic — the first ever pavement marking of its kind.

In Arizona, as well as Jacksonville, the highway is designated the "Pearl Harbor Memorial Highway". The portion through Phoenix is named the "Papago Freeway".

In Houston, from the western suburb of Katy to downtown, I-10 is known as the "Katy Freeway" and east of downtown, it is known as the "East Freeway."

Alternate Routes

I-310 and I-510 are parts of what was slated to be I-410 and act as a southern bypass of New Orleans, Louisiana. I-610 is a shortcut from the eastern to western portion of New Orleans avoiding the I-10's detour into New Orleans' central business district.

I-12 between Baton Rouge and I-59 near the Louisiana/Mississippi state line is actually a shorter route than I-10 between the two adjoining points, since I-10 dips to the south to go through New Orleans. Those traveling to or from Baton Rouge who do not wish to detour into New Orleans should leave I-10 and take I-12 for its entire route until it again meets with I-10.

Notes

• In September 2004, Hurricane Ivan's storm surge pushed up and washed out part of I-10 at the causeway over Escambia Bay near Pensacola, Florida. Westbound lanes had only a couple of sections missing, while eastbound lanes are almost completely gone for a ¼-mile (400m) section. [1] (http://www.wesh.com/news/3741143/detail.html)

• In January 1994, the I-10 overpasses over La Cienega and Venice Boulevards in Los Angeles, California collapsed during the Northridge earthquake. This section of freeway bears one of the heaviest traffic loads in California, and was reopened just 66 days later after emergency around-the-clock construction.

• The interstate's route through Phoenix was hotly contested in the 1960s and 1970s. A plan proposed by the Arizona Department of Transportation involved city block-sized 270-degree "helicoils" that would connect motorists to freeway lanes 100 feet (30 m) in the air, but voters killed it in 1973 as a result of opposition from the Arizona Republic and a growing nationwide anti-freeway sentiment. Ten years later, ADOT unveiled the current below grade plans. Despite local opposition, Interstate 10 was finally completed on August 10, 1990.

• I-610 in New Orleans and the aforementioned I-12 make I-10 one of only two interstates in the country to have two "bypasses" shorter than its normal travel. The other is I-64, which has two shorter "bypasses" in the Hampton Roads area.

• I-10 is one of the very few interstates that have at-grade intersections (roads that intersect it at a 90 degree angle, as opposed to an overpass with on and off ramps). They occur in western Texas.

• I-210 was planned as a bypass of Mobile, Alabama, but it was never completed. The highway was eventually renamed I-165.
