Business Spur I-40 - Glenrio

I-40 east at Business Loop I-40 - Glenrio, TX — Business Spur I-40 departed from Interstate 40 east at Exit 0 for the ghost town of Glenrio. Signed here as loop instead of a spur, the design of a sign replacement made a year later retained the error. Photo by Robert Lee (06/17/06).

Business Spur I-40A connects Interstate 40 with Historic U.S. 66 leading west back into New Mexico from Exit 0. The 0.779 mile segment was designated on June 21, 1990 as a mileage transfer from State Loop 504.

Historic U.S. 66 travels west to the former settlement of Glenrio at the state line. A short distance west from there is impassable segment of U.S. 66 that turned northward across Trujillo Creek. U.S. 66 originally curved northward across the alignment of I-40 west toward Exit 369 with NM 93 south / NM 392 north.
