The section of Interstate 40
Interstate 40
which runs between Memphis and Nashville is often referred to as the Music Highway . During reconstruction, a long section of I-40 through downtown Knoxville near the central Malfunction Junction was completely closed to traffic from May 1, 2008 and not reopened until June 12, 2009 with all traffic redirected via Interstate 640 , the northern bypass route. The redesigned section now has additional lanes in each direction, is less congested, and has fewer accidents.

In North Carolina
North Carolina
, I-40 travels 421 miles (678 km). It enters the state as a winding mountain freeway through the Great Smoky Mountains which frequently closes due to landslides and weather conditions. It enters the state on a mostly north-south alignment, turning to a more east-west alignment upon merging with U.S. Route 74 at the eastern terminus of the Great Smoky Mountains

Expressway . From there the highway passes through Asheville , Hickory , and Statesville before reaching the Piedmont Triad

. Just east of the Triad city of Greensboro, North Carolina it merges with I-85 and the two roads split again just west of the Research Triangle

area, passing along the southern parts of Durham and Raleigh . From the Triangle to its eastern terminus in Wilmington , it once again takes a more north-south alignment. Sign displaying distance to Barstow in Wilmington

HISTORY

For about 1,000 miles (1,600 km), I-40 follows the general route of Beale\'s Wagon Road from Arkansas
Arkansas
to California. Beale's Wagon Road was built in 1857–59 by a team led by Lt. Edward Fitzgerald Beale using a team of camels as pack animals .

In Albuquerque, New Mexico, I-40 was originally meant to replace Central Avenue through the center of the city. However, due to development and public opposition, a route running to the north of that one was chosen. The freeway intersects Central Ave. at both ends of the city.

In 1957, the California
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. Then, U.S. Rte-40 was decommissioned in California
California
in 1964, as a part of a major revamping of California's overall highway numbering system, so the problem disappeared.

The California
California
State government submitted State Route 58 between Barstow and Bakersfield for I-40 extension potential in 1956 and 1968, though those requests were rejected. This portion of SR 58 was once signed as the U.S. Route 466 .

From 1963 to 1966, the US government considered a plan, part of Operation Plowshare , to use atomic bombs to excavate a path for I-40 through California. The project was scuttled largely due to the cost of developing the explosives and due to the unavailability of a "clean bomb".

In Memphis , I-40 was originally intended to go through the city's Overton Park toward downtown. Several miles of interstate were actually built within the I-240 loop. That portion of highway still exists, and it is in regular use as the non-Interstate Sam Cooper Boulevard , reaching the eastern end of the Chickasaw Country Club. Environmentalist opposition, combined with a victory in the United States Supreme Court by opponents of the Overton Park route (see Citizens to Preserve Overton Park v. Volpe ) forced abandonment of the original plans, and the road never reached the park. For over 20 years, I-40 signs existed on the dead-end route toward Overton Park. Eventually, the northern span of the I-240 loop was redesignated as I-40.

In 1971, the North Carolina
North Carolina
State Highway Commission approved a plan to extend I-40 from Research Triangle
Research Triangle
Park to Interstate 95 , a distance of 41 miles, at a cost of $75 million. Most of the highway would be four lanes, though six lanes were likely near Raleigh , where I-40 would extend the Beltline . Several routes were being considered, but at the time, the most likely route would have ended north of Smithfield .

When the last portion of I-40, connecting Wilmington to Raleigh, was completed in the late 1980s, Charles Kuralt stated:

“ Thanks to the interstate highway system, it is now possible to travel from coast to coast without seeing anything. ”

Originally, I-40 was constructed through downtown Winston-Salem , and it continued to follow that route until a new urban bypass route was built. After the bypass was completed around 1992, I-40 was relocated to the new freeway. The old highway was then redesignated as Interstate 40
Interstate 40
Business , creating a business route that is actually an expressway for its entire length, a rarity among business routes. There are arguments that the former I-40 expressway in Winston-Salem should become an interstate again, especially since the road is currently undergoing an upgrade. There is one even loop numbers left for I-40, Interstate 640. Interstate 840 was recently available, however, since the NCDOT has had plans to use it for the northern loop of a beltway that is being built around nearby Greensboro . The collapsed section of the Interstate 40
Interstate 40
bridge, May 31, 2002

The I-40 bridge disaster occurred on May 26, 2002 when a barge collided with a bridge foundation member near Webbers Falls, Oklahoma , causing a 580-foot (177 m) section of the I-40 bridge to plunge into the Arkansas
Arkansas
River . Automobiles and semi-trailers fell into the water, killing fourteen people.

The " Big I " I-25 and I-40 interchange in Albuquerque, New Mexico, was given an honorable mention by the United States Department of Transportation and the Federal Highway Administration for excellence in urban highway design in 2002.

Landslides are common in the Pigeon River Gorge section along the Tennessee
Tennessee
and North Carolina
North Carolina
border. Here the roadway was cut into the slopes of several steep mountains. Accidents on the winding road are also common especially during bad weather. On October 25, 2009, Interstate 40
Interstate 40
was closed at the North Carolina
North Carolina
and Tennessee
Tennessee
border due to a landslide at Mile
Mile
Marker 2.6 just east of the Tennessee
Tennessee
state line. All Traffic was detoured via Interstates 26 and 81, and non-heavy load traffic via US 25/70. The roadway was reopened on April 25, 2010, with some remaining limitations on westbound traffic.

City, the designation I-440 had been given to a stretch of Interstate Highway
Interstate Highway
from I-240 to US-66. It was a part of Grand Boulevard that had been built in compliance with Interstate standards . In 1982, as part of Oklahoma's "Diamond Jubilee", I-44's western terminus was moved from the I-35/I-44 junction to the Texas/Oklahoma state-line via the Belle Isle Freeway (connecting I-440 with I-35); I-440, the H. E. Bailey Turnpike; and the turnpike connector road on the eastern edge of Lawton, Oklahoma
