Santa Fe Railway in Yucca along with the approach roads to the overpass. In April 1951, a contract to construct of the new bypass was given to the W.J. Henson company for $234,872 (equivalent to $ in ). The Highway Department created another contract job in October 1951 to pave and construct a further of the bypass route, in hopes of speeding up the project. The Phoenix-Tempe company was again awarded the contract. Despite the highway's priority and rushed construction, the Yucca Overpass was delayed for several months due to a shortage of available steel. The steel was finally delivered to begin the overpass construction on January 25, 1951. Construction of the bypass continued through late 1951 to the middle of 1952. By August 1952, construction on the bypass was winding down. By this point, had been completed with the final under construction. The bypass was completed and opened to traffic on September 17, 1952. The overall construction of the bypass from 1950 to 1952 was done at record speed at the time, being the fastest major highway construction project within the state's history. US 66 was rerouted onto the new bypass, removing Oatman from US 66. The new route ran along level ground close to the railroad, from Topock to Kingman through Yucca. The bypassing of Oatman lead to the town's decline and near abandonment, while Yucca enjoyed a small period of increased success from US 66 traffic. Oatman Highway remained an undesignated state highway until September 2, 1955, when it was completely transferred to Mohave County. During the late 1940s and early to mid-1950s, the popularity of US 66 greatly increased. There was a great increase in postwar driving, with more people taking the nation's roads than in decades past. To meet the increase in postwar travel, the number of restaurants, gas stations and motels along the route grew. The number of creative attractions and landmarks also grew, in an attempt to attract further tourism, such as the Wigwam Motel in Holbrook, where every room was built to resemble a Native American tipi. Other popular tourist attractions and stopping points along the highway included the Two Guns, the Twin Arrows Trading Post, Painted Desert Trading Post and Grand Canyon Caverns. American actor and musician Bobby Troup composed the song "(Get Your Kicks on) Route 66", while traveling down the highway with his wife in 1941. This song was
