Interstate 40 runs 421 miles (678 km) through the state of North Carolina from the Tennessee state line in the west to its eastern terminus in Wilmington. The middle segment of I-40 in the state is sometimes informally known as the "Tobacco Road" since it is the major thoroughfare linking the "Big Four" universities in the Tobacco Road sports rivalry.^[2]

Route description

Pigeon River Gorge

The first section of I-40 in North Carolina is the section that travels through the Pigeon River Gorge in Haywood County. Known locally as simply "The Gorge", this part of I-40 cuts a path from the Tennessee state line to Waynesville. This section of the interstate is fairly curvy and tends to become a bit narrow in some places when compared to other portions of the highway. Because much of the road was cut through mountainside, concrete retaining walls have been built on both sides of the road and in the median, cutting down on the width of the breakdown lanes. Coupled with speeding vehicles, the extremely thick fog that tends to plague the area, and little room to maneuver in case of accident, this area has become notorious for its severe and many times fatal accidents. It is reported that a person is 20 times as likely to die on I-40 in Haywood County than they would be to win the Powerball lottery, which equals to be twice the average of any other Interstate Highway in North Carolina.^[3]

Even some minor accidents have been known to tie up traffic in this area, because there is little room to move accidents off or to the side of the road with the terrain. Speeding semi trucks have been a problem in the gorge and have subsequently led to many accidents. In 2002 and 2003, two state troopers were killed in two separate accidents by speeding trucks that drifted off the road and hit their police car conducting a traffic stop. This led the North Carolina Highway Patrol to crack down on speeding tractor trailers and speeders in general through the area.

This portion of the highway is also notorious for rockslides and rocks falling onto the highway. The main cause is an engineering flaw, in that sections of the highway have been built on the north side of the Pigeon River, where the rock strata foliate towards the highway.

2009 rockslide and closure

On October 25, 2009, a major rockslide, including boulders described as the size of houses, blocked the highway completely at mile marker 2.6.^[4] The section reopened with westbound traffic restricted to one lane on April 25, 2010.^[5] Trucks wider than 12 feet are still prohibited through the slide area, and must still use the I-26 and I-81 detour.^[6]

Through Greensboro

The six routes of Death Valley in 2007. US 421 has since been rerouted; the shield was removed in 2009.

Throughout much of the Greensboro metropolitan area, I-40 follows a stretch of six-lane freeway carrying five other routes: Business I-85, U.S. Route 421, U.S. Route 29, U.S. Route 70, and U.S. Route 220. This 2.5-mile (4.0 km) corridor begins in the west at the I-40/Business I-85/Randleman Road interchange and ends in the east at the U.S. Highway 29/70/220/Martin Luther King Jr. Boulevard junction. Both of these interchanges are quite unusual in design and are often operating at above full capacity, leading to frequent traffic jams and traffic incidents.

I-40 through Greensboro officially bears the name Preddy Boulevard. The nickname "Death Valley" was originally given to the 2.5-mile (4.0 km) segment of I-85 in Greensboro in 1963 after seven people died in accidents there the previous year.^{[citation needed]} In 1964, the state unveiled a plan to eliminate Death Valley's flaws.^{[citation needed]} After numerous construction projects, conditions improved along the corridor, but the nickname remained. Over the years, increased traffic through the area has given the nickname "Death Valley" new meaning. The nickname is well-known by locals, news reporters, and frequent travelers.^{[citation needed]}

One major problem with the highway is that the U.S. 29/220/70 southbound lanes merge from the right, and exit to the left. Thus, through traffic on I-40 west and US 29 south (a major route from Virginia to Charlotte) must all merge to the other side of the freeway. A study conducted by state traffic engineers from May 1, 2006 to April 30, 2008 (the period between the I-85 relocation and I-40's relocation) concluded that "the Death Valley area" had an accident rate "higher than average for urban interstates... but the [route] was safe anyway"^[7] There were no fatalities during the study period, but a large number of rear-end collisions.^[7]

Through The Triangle

I-40 through the Research Triangle varies in width, from 4 lanes to 8 lanes depending on the location. It serves as a major artery between Raleigh and Durham (the other being US-70). Work is in progress to widen the 4-lane stretch between Wade Avenue and US 1/I-440 through Cary which has been especially congested of late.^{[8][dated info]}

I-40 is called Dan K. Moore Freeway from Durham to Wade Avenue and Tom Bradshaw Freeway through Raleigh. The James E. Harrington Freeway stretches to Newton Grove.

Eastern North Carolina

I-40 is 4 lanes from the western edge of Raleigh to Wilmington as it crosses through mostly agrarian land.

History

I-40/85 through Burlington

Construction

Construction on I-40 through North Carolina officially began in 1956 along the Pigeon River in Haywood County. This would be the first section of I-40 to be built anywhere in the country. This section was completed in 1968 and at that time contained the only Interstate Highway tunnels east of the Mississippi River. Construction continued through the 1950s and 1960s, with much of the interstate being constructed in the 1960s. The last portion of I-40 to be completed, between Raleigh and Wilmington was opened on June 29, 1990, by Governor James G. Martin. Much of Martin's election campaign in the mid-1980s was hinged on opening this section for the sake of improving access to the North Carolina State Port at Wilmington.^[9]

A standard distance sign that once existed near the start of the westbound section of I-40 in Wilmington indicates the distance to Barstow, California as 2,554 miles (4,110 km). However, NCDOT has stated that it will not be replaced after frequent thefts.^[10]

Rockslides in the Pigeon River Gorge

In 1985, a severe rockslide buried the westbound entrance to one of two tunnels that carry the highway through the gorge. Repair of the slide area and the tunnel required shifting westbound traffic to the eastbound tunnel, while eastbound traffic was diverted onto a temporary viaduct around the tunnels.

In July 1997, a rockslide near the Tennessee state line closed the road for nearly six months.^[11]

On October 25, 2009, another rock slide occurred about 3 miles (4.8 km) from the Tennessee state line. The rock slide blocked both lanes of traffic and was estimated to be 100 feet long and up to 50 feet high.

Greensboro I-40 relocation

Map showing changes made to I-40's routing between 2004 and 2008

In February 2008, Interstate 40 was rerouted onto the new Greensboro Urban Loop. The former path of I-40 became Business Loop I-40.^{[citation needed]}

NCDOT received many complaints by local residents and motorists on the confusion between mainline Interstate 40 and Business 40, which used a shield differing only in color from the mainline I-40. Greensboro residents also had concerns with the resulting increased traffic. On September 12, 2008, seven months after the initial switch, NCDOT officials got permission from the FHWA to restore Interstate 40 back to its original route through the city, decommission Business Interstate 40, and leave I-73 and I-85 as the only interstates signed along the Loop. Exit numbers on the I-40 part of the Loop that ran with I-73 will be replaced with I-73 exit numbers from the I-85/US 220 southern interchange around the loop to the western I-40 interchange. US 421 was officially rerouted to replace most of I-40 around Greensboro.^[12]

Work on re-signing the Loop and the former Business 40 began on May 8, 2009, with the exception of the eastern I-40/85 interchange, where signs were changed in the fall of 2008.^[13][12] The re-signing project was completed on July 1, 2009.^[14]

The current alignment of I-40 is four miles (6 km) shorter than the 2008 Urban Loop routing,^[7] and is a quicker route for any vehicle consistently traveling at the posted speed limits.
