Interstate 81 in Tennessee
Interstate 81 (I-81) is an 855-mile-long (1,376 km) Interstate Highway stretching from Dandridge, Tennessee, northward to the Thousand Islands Bridge at the Canadian border near Fishers Landing, New York. In Tennessee, I-81 travels 75.66 miles (121.76 km) from its southern terminus at I-40 in Dandridge to the Virginia state line in Bristol. In addition, the route serves the Tri-Cities region of northeast Tennessee, but bypasses most cities that it serves, instead providing access via interchanges with state and federal routes. In Tennessee, I-81 remains in the Ridge and Valley topographic region of the Appalachian Mountains, and runs in a more northeast-southwest direction.

Route description
Interstate 81 begins in at an interchange with Interstate 40 near Dandridge in Jefferson County. About 4 miles (6.4 km) later is an interchange with SR 341, which connects to SR 66 a short distance later, providing access to Morristown. 4 miles (6.4 km) later, I-81 crosses into Hamblen County and meets U.S. Route 25E south of Morristown. Continuing through mostly rural terrain, I-81 has an interchange with SR 160, the final Morristown exit, about 4 miles (6.4 km) later. About 9 miles (14 km) later, the interstate crosses over a ridge and into Greene County. About 5 miles (8.0 km) beyond this point is an interchange with US 11E, which provides access to Greeneville to the southeast and Bull's Gap to the northwest. Continuing through a predominantly rural and agricultural area, I-81 reaches SR 70, which connects to Greeneville to the south and Rogersville to the north. Beyond this point, the interstate remains in a predominantly rural and agricultural area, and begins a slight uphill climb, with the northbound lanes utilizing a truck climbing lane for about 1.5 miles (2.4 km) near the community of Jearoldstown, where the route also shifts slightly to the northeast. A few miles later, I-81 shifts sharply east and crosses into Washington County. Less than a mile later is an interchange with SR 93, which provides access to Jonesborough to the south and Fall Branch to the north. I-81 then turns northeast again, and about 3 miles (4.8 km) later enters Sullivan County. Entering a semi-urbanized part of the Tri-Cities area, I-81 connects to I-26 and US 23 in a cloverleaf interchange about 3 miles (4.8 km) later. This route provides access to Kingsport to the north and Johnson City to the south. A little over two miles later is an interchange with SR 36, another major connector between these two cities. I-81 then crosses the Holston River about a mile later, and begins another slight uphill climb, once again gaining a truck climbing lane on the northbound lanes. About 3 miles (4.8 km) later the truck lane terminates at an interchange with SR 357, a connector to the Tri-Cities Regional Airport, and the route continues through the semi urban area, briefly shifting eastward and crossing a ridge about 4 miles (6.4 km) later. Shifting northeastwardly again, I-81 has an interchange with SR 394 near the city of Blountville. Beyond this exit, the route crosses a slight upgrade once again, before reaching a relatively flat stretch again. About 5 miles (8.0 km) later, I-81 reaches Bristol and widens to six lanes. The route then has a cloverleaf interchange with US 11W, before crossing into Virginia 1 mile (1.6 km) later.
History
During its design phase in the early 1960s, I-81 was originally intended to follow the route of US 11W from Bristol to Knoxville, but efforts led by then Senator Herbert Walters of Morristown had the project redirect southward through Greene, Hamblen, Jefferson counties.[2]
One of the first sections to be opened to traffic was the 1 mile (1.6 km) segment between US 11W and the Virginia state line, opened by the early 1960s.[3] The interchange with I-40 was also constructed in the earlier 1960s, but not immediately opened to traffic. The segment between the southern terminus with I-40 and SR 160 in Hamblen County was completed in late 1966.[4] Like most of the interstates in Tennessee, priority was generally given to completing sections in Middle and West Tennessee over East Tennessee, and as a result, most of I-81 in Tennessee was not constructed until after the late 1960s.[3] On December 10, 1970, I-81 was opened between SR 160 near Morristown and US 11E near Mosheim.[5] The contracts for most sections of the route were awarded in 1969 and 1970.[6] On December 20, 1974, two lanes of the final section in Tennessee, the 43 miles (69 km) section located between US 11E near Mosheim and SR 126 near Blountville, were opened to traffic,[7][8] and the section was completed on August 27, 1975, when the section was fully opened to traffic.[9]
