US 78 enters Tennessee along Interstate 55 from Arkansas and shortly after diverges from I-55 onto E.H. Crump Boulevard. It is concurrent with US 61, US 64, US 70, US 79 an SR 1 until Third Street/B.B. King Boulevard. US 61 turns south onto SR 14 (Third Street) at this intersection. US 64, US 70, US 79 and SR 1 turn north onto SR 4 (Danny Thomas Boulevard), while southbound SR 4 becomes concurrent with US 78 and continues along E.H. Crump Boulevard. Around I-240, the road changes names to Lamar Avenue and continues southeastwardly to the Mississippi state line.[1]
Before the extension of this roadway into Arkansas, US 78 ran along MLK Avenue (formerly Linden Street) and Somerville Street until E. H. Crump Boulevard, turning onto Lamar Avenue. This former portion of US 78 was overlapped in its entirety by State Route 278 (SR 278).
In Memphis, US 78 is historically known as Pigeon Roost Road, and some aborted sections of the highway in Mississippi also claim that name as well as Lamar Avenue.

Alabama
US 78 is a major east–west U.S. highway across the central part of Alabama. It is internally designated State Route 4 (SR 4) by the Alabama Department of Transportation, though the only section of State Route 4 that is signed is along portions mainly west of Jasper. The section from the Mississippi state line to near Graysville is concurrent with Interstate 22; from Graysville south to Birmingham, US 78 takes its original routing. East of Birmingham to the Georgia state line, US 78 has been replaced as a major through-route by Interstate 20. The two routes roughly parallel each other, with junctions at Leeds and Pell City.[2]
West of Jasper, old US 78 is signed as AL 118 to Guin, and the segment from Guin northward to I-22 at Hamilton is signed as US 43/US 278.
Georgia
US 78 enters Georgia in Haralson County, and then proceeds through Carroll County and Douglas County. In Douglasville, located in Douglas County, US 78 runs through the downtown, historical part of the city. It is the original thoroughfare for these Georgia counties.
The route then continues eastward through
After entering Decatur in DeKalb County, US 78 departs from Ponce de Leon Avenue to head northeast. South of the site of North DeKalb Mall, another short freeway portion begins — leading from just inside the eastern rim of Interstate 285 (the Perimeter) to the suburbs of Clarkston, Tucker, Stone Mountain, and Snellville. This portion is named the Stone Mountain Freeway, and provides an excellent view of Stone Mountain for eastbound motorists.
The route then proceeds east across
South Carolina
US 78 provides the most direct route between Augusta and Charleston, through the South Carolina Lowcountry. Crossing Savannah River into the state, it goes northeast into Aiken before going southeasterly through the cities and towns of Williston, Blackville, Denmark, Bamberg, Branchville, and St. George. East of Dorchester, it parallels Interstate 26 into downtown Charleston, where it ends.[4]
History
This section needs expansion. You can help by adding to it. (October 2014) |
In western Alabama, the historical name of US 78 is
Throughout the 2000s, US 78 has been gradually upgraded into a four-lane freeway in Mississippi and Alabama and signed as I-22. US 78 is concurrent with I-22 from Byhalia, Mississippi to just outside of Birmingham, Alabama, only branching off just outside of Graysville, Alabama with I-22 traveling about 11 miles (18 km) eastward to its terminus at I-65.[5]
On October 25, 2023, the Arkansas Highway Commission voted unanimously to extend the US 78 designation into
Future
US 78 and SR 4 in Memphis, Tennessee is currently being upgraded between the Mississippi state line and SR 176, a distance of about 5.1 miles (8.2 km). The route, Lamar Avenue, sees heavy freight traffic and has "crippling congestion." The work includes expanding the road from four to six lanes, adding three new interchanges, and upgrading additional ones. The work is being done in three segments with the first one starting in 2018.[9]
