IH 20 replaced all of U.S. 80 from Fort Worth to IH 10 west of Toyah. Several Business Loops follow the original U.S. 80 alignments through cities along the 420-mile drive between IH 10 near Kent and the split with IH 30. East from Mesquite, U.S. 80 remains posted on on a parallel alignment to IH 20 en route to Shreveport, Louisiana and Cuba, Alabama.
