I-40 Overview: Coast to Coast Through Route 66 Country

Unlike I-10 and I-80, which serve as primary coast-to-coast commercial arteries, I-40 combines long-haul trucking with significant tourism traffic. The highway replaced most of historic Route 66, and travelers still seek out surviving segments and roadside attractions. From the desert isolation of California and Arizona to the music cities of Memphis and Nashville in Tennessee, I-40 offers one of America's most diverse driving experiences.

According to the FHWA, real-time traffic monitoring helps drivers make safer, more informed decisions.

Major Cities Along I-40

State-by-State I-40 Guide

California (155 miles)

I-40 enters California from Arizona at Needles and crosses the Mojave Desert to its western terminus in Barstow. This stretch offers little besides desert landscape, truck stops, and Route 66 nostalgia. Needles regularly records some of the hottest temperatures in the nation, with summer highs exceeding 115 degrees F. The Barstow junction connects to I-15 north toward Las Vegas or south toward Los Angeles.

• Key Cameras: Barstow interchange, Needles border crossing
• Hazards: Extreme heat, blowing sand, limited services
• Route 66: Original alignment visible parallel to I-40

Arizona (359 miles)

Arizona offers I-40's most dramatic elevation changes. From Needles, the highway climbs through Kingman to the pine forests around Flagstaff at 7,000+ feet, then descends through the Painted Desert toward New Mexico. Flagstaff serves as the Grand Canyon's southern gateway, attracting significant tourist traffic. The Meteor Crater exit provides access to the famous impact site, while Winslow draws Route 66 enthusiasts ("Standing on the Corner").

• Key Cameras: Flagstaff downtown, Kingman interchange, Winslow area
• Hazards: Summer monsoons (July-September), winter snow around Flagstaff
• Attractions: Meteor Crater, Petrified Forest, Painted Desert

New Mexico (374 miles)

New Mexico's I-40 segment runs through high desert plateaus averaging 5,000-7,000 feet elevation. Albuquerque dominates the route, with the notorious "Big I" interchange where I-40 meets I-25 creating regular congestion. The city's 400,000+ residents and constant construction make cameras essential. Gallup near the Arizona border and Tucumcari near Texas retain strong Route 66 character with vintage motels and neon signs.

• Key Cameras: Big I interchange, Albuquerque metro, Gallup
• Hazards: High-altitude driving, winter ice, wind gusts
• Route 66: Historic districts in Gallup, Grants, Albuquerque, Tucumcari

Texas (177 miles)

Texas claims I-40's shortest state segment, but the Panhandle stretch is memorable. Amarillo anchors the route with Cadillac Ranch (ten half-buried Cadillacs) and the Big Texan steakhouse. The flat, treeless landscape creates dangerous wind conditions, particularly for high-profile vehicles. Cattle trucks dominate the roadway, heading to and from the region's massive feedlots. Winter blizzards can close the highway with little warning.

• Key Cameras: Amarillo metro, Texas-New Mexico border
• Hazards: Severe crosswinds, cattle truck traffic, winter closures
• Attractions: Cadillac Ranch, Big Texan, Route 66 Historic District

Oklahoma (331 miles)

I-40 crosses Oklahoma through the heart of Tornado Alley. Oklahoma City presents the busiest traffic, with the I-35/I-44 interchange creating multiple conflict points. The state maintains extensive camera coverage due to frequent severe weather and ongoing construction projects. El Reno (west of OKC) holds the record for the widest tornado ever recorded (2.6 miles), a reminder of the region's weather dangers.

• Key Cameras: Oklahoma City interchanges, I-35 junction, I-44 junction
• Hazards: Tornadoes (April-June), ice storms, perpetual construction
• Route 66: Historic districts in Clinton, El Reno, Oklahoma City

Arkansas (284 miles)

Arkansas marks I-40's transition from Western plains to Southern landscapes. Fort Smith at the Oklahoma border provides camera coverage of the Arkansas River crossing. Little Rock serves as the primary traffic hub, with I-30 connecting to Dallas/Fort Worth and I-440 providing a bypass option. The rolling Ozark foothills give way to delta flatlands approaching Memphis.

• Key Cameras: Fort Smith, Little Rock metro, I-30/I-440 interchanges
• Hazards: Ice storms, fog in river valleys, flooding
• Traffic Patterns: Little Rock rush hours, trucking corridors

Tennessee (455 miles)

Tennessee gives I-40 its longest single-state segment, connecting Memphis, Nashville, and Knoxville. The Memphis I-55 interchange includes the iconic Mississippi River bridge crossing into Arkansas. Nashville's I-65/I-24 interchange experiences severe congestion as the city's population boom strains infrastructure. Knoxville's I-75/I-81 junction serves as a major truck crossroads. Fog in the valleys between cities creates recurring visibility hazards.

• Key Cameras: Memphis bridges, Nashville downtown, Knoxville interchanges
• Hazards: Dense fog, Nashville congestion, mountain curves east of Knoxville
• Major Interchanges: I-55 (Memphis), I-65/I-24 (Nashville), I-75/I-81 (Knoxville)

North Carolina (420 miles)

I-40's eastern segment climbs into the Great Smoky Mountains before descending through Asheville and the Blue Ridge Parkway area. This section features some of the most challenging terrain on the entire route, with steep grades and sharp curves through mountain passes. The route then crosses the Piedmont through Winston-Salem and the Research Triangle (Raleigh-Durham) before reaching its Atlantic terminus in Wilmington. Winter weather in the mountains can close the highway while the coast remains clear.

• Key Cameras: Asheville area, Raleigh-Durham metro, Wilmington approach
• Hazards: Mountain grades, winter ice, fog, Blue Ridge weather changes
• Scenic Highlights: Great Smoky Mountains, Blue Ridge Parkway access
