This article is about the section of U.S. Route 66 in New Mexico. For the entire route, see
U.S. Route 66.
U.S. Route 66 (US 66, Route 66) in New Mexico ran east–west across the central part of the state, along the path now taken by Interstate 40 (I-40). However, until 1937, it took a longer route via Santa Fe, now roughly I-25 and US 84. Large portions of the old road parallel to I-40 have been designated State Road 117 (NM 117), NM 118, NM 122, NM 124, NM 333, three separate loops of I-40 Business, and state-maintained frontage roads.
It is one of the roads on the Trails of the Ancients Byway, one of the designated New Mexico Scenic Byways.
