Travel directions

The Hernando de Soto Bridge over the Mississippi River in Memphis.

Memphis

Interstate 40 in Arkansas comes from Little Rock and crosses the Mississippi River via the Hernando de Soto Bridge, entering the city of Memphis. I-40 has 2×3 lanes on the bridge, but there are only 2×2 lanes for through traffic near downtown Memphis for a short time. An interchange with Interstate 240. will follow on the east side of downtown, which forms the Memphis ring road. Here, I-40 follows the Memphis North Ring, a 2×3 lane route through the suburbs of the city. On the east side of Memphis, there is a second interchange with I-240. I-40 still has 2×4 lanes in the eastern suburbs of Memphis, but soon narrows back to 2×2 lanes again. At Arlington, it interchanges with Interstate 269, which forms Memphis’ Outer Beltway.

Western Tennessee

I-40 at US 641 at Camden.

Then follows a nearly 200-mile stretch from Memphis to Nashville. This part leads through rural area that becomes heavily forested to the east and also becomes a bit more hilly. I-40 has 2×2 lanes on this section. Of the places on the route, the small town of Jackson holds the most significance. East of Camden, a fairly large bridge crosses the Tennessee River, an important dividing line in the state. A little further east one crosses the smaller Duck River. I-40 intersects a relatively large number of other roads, but few of them are of major importance.

Nashville Region

I-40 between Nashville and Lebanon.

I-40 then passes through the Nashville metropolitan region. There is also a major bypass, Interstate 840, which forms a major bypass from Dickson to Lebanon that allows through traffic to bypass the entire city. I-40 has 2×3 lanes from the Bellevue suburb and then enters more densely built-up areas. I-40 has many interchanges with other highways in Nashville, including two with Interstate 24, Interstate 65, and Interstate 440. I-440 forms a minor bypass of Downtown Nashville while I-40 has a short double numbering with both I-24 and I-65. I-40 also has two interchanges with State Route 155, the Briley Parkway that forms Nashville’s northern bypass.

Through Nashville, I-40 has between three and five lanes in each direction, with mostly 2×3 lanes and rapidly sequential interchanges. I-40 runs along the west and south sides of Downtown Nashville and traffic has a view of the city skyline. In the east of the city, I-40 is the primary access point to the Nashville International Airport, which is also the widest part of I-40 with 2×5 lanes. I-40 then has 2×4 lanes until just before Lebanon.

Central Tennessee

I-40 then follows a 200-mile stretch from Nashville to Knoxville. East of Lebanon, I-40 again has a longer stretch of 2×2 lanes and leads through a rural and hilly area, which has an alternation of forests and meadows. The main places on this part of the route are Lebanon and Cookeville. Various parts of I-40 have a wide median strip. East of Cookeville, I-40 also has more slopes, the highway rises here from 350 to 600 meters above sea level. Also between Crossville and Kingston, the highway has slopes and sharp turns, descending again into the valley of the Tennessee River.

Knoxville Region

I-40 at Knoxville.

I-40 merges into Interstate 75 at Farragut coming from Chattanooga. I-40 and I-75 are double-numbered here for nearly 20 miles to the west side of Knoxville. This stretch is already highly suburbanized and I-40 is a wide 2×4 lane highway. Interstate 140 also joins in this area as Knoxville’s southern bypass.

On the west side of Knoxville, I-75 exits and then follows Interstate 640, which forms the city’s northern bypass. I-40 has 2×4 lanes to Downtown Knoxville, east of which are 2×3 lanes. Around downtown is a complex road structure with overpasses and many interchanges, including with Interstate 275, which provides access to I-75 toward Cincinnati. A second interchange with I-640 follows east of Knoxville.

Eastern Tennessee

From Knoxville, I-40 heads east for 50 miles and has 2×3 lanes until the interchange with Interstate 81. Here traffic splits, I-40 heads southeast to North Carolina while I-84 heads northeast to Virginia. I-40 then has 2×2 lanes and crosses Douglas Lake, a large reservoir. After this, the highway enters the Great Smoky Mountains. I-40 then follows the narrow valley of the Pigeon River to the border with North Carolina, this stretch is winding but does not yet have many elevation changes. Interstate 40 in North Carolina then continues to Asheville.
