Victory Highway

Most of the western section of US 40 follows the former route of

, a road that once linked Kansas City to San Francisco. The road was named as a memorial to fallen World War I veterans. Other than two sections (one in California and one in Kansas/Colorado) most of the original route of US 40 west of Kansas City used Victory Highway. According to a 1926 guide published about the Victory Highway, it was the fastest route between San Francisco and Salt Lake City, allowing travellers to complete the trip "comfortably and in high gear in from 3 to 4 days." Controversy over the routing of US 40 over the Victory Highway led to a "divided route", with US 40S following the Victory Highway and US 40N taking a more northerly route.
