All roads in downtown Gallup dead-end onto Route 66, which runs uninterrupted through town – take Exit 20 or 22 from Hwy 40 to access the best of Route 66 downtown. The historic district is lined with about 20 structures of historic and architectural interest, built between 1895 and 1938. Most are located along 1st, 2nd and 3rd Sts between Hwy 66 and Hill Ave and are detailed in a brochure found at the visitor center. Among these is the small Gallup Historical Museum , in the renovated, turn-of-the-19th-century Rex Hotel.
