Business Loop I-40 - Gallup

Former Business Route

I-40 east at Business Loop I-40 - Gallup, NM
Advancing to Exit 16 with the west end of the Gallup business loop on Interstate 40 east. This route was replaced by New Mexico State Road 118. 06/28/08

This business route followed Historic U.S. 66 for 9.5 miles between Exits 16 and 26. The route is still acknowledged on freeway guide signs and on a few shields in Gallup as of 2016, but is inventoried otherwise as the easternmost stretch of New Mexico State Road 118. NM 118 travels 36.85 miles along old U.S. 66 from the Arizona state line to I-40 at Exit 36.

Gallup is the south end of U.S. 491. U.S. 491 was formerly designated as U.S. 666 until AASHTO approved its renumbering on May 30, 2003. Business Loop I-40 across the city was inventoried by the New Mexico Department of Transportation (NMDOT) as BL-31-P.
