ⓘ U.S. Route 163

U.S. Route 163 is a 64-mile U.S. Highway that runs from US 160 northward to US 191 in the U.S. states of Arizona and Utah. The southernmost 44 miles of its length are within the Navajo Nation. The highway forms part of the Trail of the Ancients, a National Scenic Byway. The highway cuts through the heart of Monument Valley and has been featured in numerous movies and commercials.

The highway was designated in 1970, replacing Arizona state route 464 and Utah state route 47 as well as part of the old alignment of us 160 in Utah. In 1981, with us 191 was routed over the Northern part of US 163, effectively truncating the Northern end to bluff, Utah, from the intersection of the Crescent. Utah briefly had plans for a different route us 163 North of bluff. These plans were rejected as a result of discrepancies between the signed route and the official definition of the American Association of state highway and transportation officials, which were not resolved until 2008. The route number does not match the numbering on U.S. roads, as the number 163 is typically used to spur us 63, however, these two backbones are connected.
