Interstate 11 - Route Description

Route Description

The proposed numbering of the highway does not fit within the usual conventions of the existing Interstate Highway grid, as it would be completely east of Interstate 15 and should therefore have a number greater than 15. But Interstate 17 already is built to the east of the I-11 alignment in Arizona, making it impossible to fit this freeway into the national grid without violating the traditional numbering convention.

From its beginning near Phoenix to the Santa Maria River, I-11 would mostly follow US 93's alignment, although the proposal for the Hassayampa Freeway by the Maricopa Association of Governments shows the likely I-11 corridor branching off from US 93 west of Wickenburg, bypassing the town. The Hassayampa Freeway is a proposed freeway that would run from Wickenburg to I-10 in Buckeye, about 40 miles (64 km) west of Phoenix.

It crosses the Santa Maria and Big Sandy rivers, as well as Burro Creek. It also passes the hamlet of Nothing.The Arizona Department of Transportation (ADOT) is widening this stretch to four lanes, including a bypass of Wikieup. It would travel northward to I-40. US 93 and I-11 would then overlap with I-40 for about 20 miles (32 km) on the east side of Kingman.

As it enters Kingman, US 93 and I-11 would split away from I-40 as US 93 becomes Beale Street, but Arizona is studying a direct freeway connection for US 93 and I-40. US 93 then passes the towns of Golden Valley, Chloride, Dolan Springs, and White Hills as it goes northwest. It crosses into Lake Mead National Recreation Area and becomes the roughly 4 miles (6.4 km) bypass of Hoover Dam as it enters Nevada.

The 71 miles (114 km) of US 93 south of Hoover Dam is now a four-lane route, from Kingman, Arizona to the Hoover Dam Bypass. It is not built to interstate highway standards, as there are scattered intersections and substandard roadway widths, medians, and other deficiencies. Part of the dual roadways are repaved, restriped sections of very-old parts of U.S. 93.

The Federal Highway Administration (FHWA) has approved the Nevada Department of Transportation's (NDOT) environmental review of a bypass around Boulder City, which would connect the end of the recently-constructed Hoover Dam Bypass east of the town at Hoover Dam to Interstate 515 west of town. The first stage of the bypass, which would offer a new connection from I-515 to US 95, is expected to begin construction in 2012.

Most of I-11's proposed route in the Las Vegas Valley already has been constructed as I-515 from Railroad Pass to Las Vegas, passing through Henderson, Paradise, and Winchester. It would then terminate, along with I-515, at I-15 in downtown Las Vegas.

Famous quotes containing the words route and/or description:

    By a route obscure and lonely,
    Haunted by ill angels only,
    Where an eidolon, named Night,
    On a black throne reigns upright,
    I have reached these lands but newly
    From an ultimate dim Thule—
    From a wild weird clime that lieth, sublime,
    Out of space—out of time.
    Edgar Allan Poe (1809–1849)

    God damnit, why must all those journalists be such sticklers for detail? Why, they’d hold you to an accurate description of the first time you ever made love, expecting you to remember the color of the room and the shape of the windows.
    Lyndon Baines Johnson (1908–1973)
