U.S. Route 78
U.S. Route 78 (US 78) is an east–west United States Numbered Highway that runs for 843.3 miles (1,357.2 km) from Cash, Arkansas, to Charleston, South Carolina.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.After crossing Peachtree Street, where US 78 marks a boundary between downtown and Midtown, US 78 is largely conterminous with Ponce de Leon Avenue.As it proceeds due east, this section of the route passes Ponce City Market and crosses the Eastside Trail of the BeltLine before skirting a number of Frederick Law Olmsted-designed parks in the Druid Hills Historic District at the eastern edge of the city.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.From there US 78 passes through Oglethorpe, Wilkes, McDuffie and Columbia Counties into Augusta and then onto one of the twin bridges across the Savannah River into South Carolina.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.
