Texhomex
Texhomex is a marker showing the tri-point of Oklahoma, Texas and New Mexico. The marker is off U.S. Highway 56 about one mile east on Texas State Line Road and the corner of Oklahoma State Line Road. There are no signs on Highway 56 in either direction.
The tri-state marker is in a pasture and can be accessed by walking over a cattle guard.
