U.S. Route 80 is an east–west
United States highway, much of which was once part of the early
auto trail known as the Dixie Overland Highway. As the "0" in the route number indicates, it was originally a cross-country route, from the
Pacific Ocean to the
Atlantic Ocean. However, the entire segment west of
Dallas, Texas, has been
decommissioned in favor of various
Interstate highways and
state highways. Currently, the highway's western terminus is at an
interchange with Interstate 30 on the
Dallas–
Mesquite, Texas city line. The highway's eastern terminus is in
Tybee Island,
Georgia, at the intersection of Butler Avenue, Inlet Avenue, and Tybrisa Street, near the
Atlantic Ocean.
