What is the distance from Canada border to tip of Texas?

The distance from the Canada border to the tip of Texas is approximately 1,900 miles. This measurement is based on a straight-line distance from the southernmost point of Texas (Brownsville) to the northernmost point of the U.S.-Canada border (near Northwest Angle in Minnesota). However, if you were to follow the actual roads and highways, the distance would be longer due to the curvature of the Earth and the specific route taken.
