After merging with I-10 and US 180, US 85 remains concurrent with them for the remainder of its length in Texas in greater El Paso's west side and upper valley regions.

The route then intersects the northern segment of Loop 375, providing connection to Canutillo and Fort Bliss.

The first AASHO route log, published in 1927, did not place US 85 in Texas but instead as terminating in Las Cruces, New Mexico.

The current local TxDOT map shows US 85 terminating on Paisano Dr. at US 62 at S. El Paso St. with no concurrent along US 62 to the border.

[2] However, the present route log of the American Association of State Highway and Transportation Officials, as AASHO is now known, shows US 85 joining US 62 to the border.
