the northeast border of Texas is the red river
The Red River (Mississippi River) forms a border between Texas and Oklahoma. It is a short border between Texas and Arkansas before entering Arkansas, turning south near Fulton, Arkansas and flowing into Louisiana. The total length of the river is 1,360 miles (2,190 km).
The distance from the northern border to the southern border of Texas is approximately 800 miles. This measurement runs from the northernmost point near the Red River to the southernmost point at the Gulf of Mexico. Texas is the second-largest state in the U.S., contributing to this significant distance.
Bordering Texas and Louisiana is the Sabine River, the Red River borders Texas and Oklahoma, and between Texas and New Mexico/Mexico is the Rio.
