U.S. Route 101
The nearly highway's northern terminus is in Tumwater, Washington: the route remains along the Olympic Peninsula's coastal perimeter west, north, and east; the northernmost point on the highway is in Port Angeles. The southern terminus of US 101 is in Los Angeles at the East Los Angeles Interchange, the world's busiest freeway interchange.
Utah State Route 71
The state legislature created State Route 71 in 1931, running south from US-40 (2100 South) along 900 East and through Draper, Corner Canyon, and Alpine to US-50/US-89/US-91 (now solely US-89) in American Fork. However, the portion across the Traverse Mountains between SR-111 (12300 South) in Draper and Alpine was never built, and was removed from the state highway system in 1935; at the same time, the southern piece from Alpine to American Fork was renumbered SR-74. In 1957, most of SR-71 was moved west two blocks to 700 East, the south end was truncated to 7700 South north of Sandy (replaced by an extension of SR-111), and the north end was extended to SR-181 (South Temple Street). This change was partially reverted in 1959, when the south end was extended back to Draper over what had just become SR-111. In 1969, the north end was cut back four blocks to SR-186 (400 South), and the south end was extended west along what had been SR-111 (created in 1931) to SR-68 (Redwood Road) in Riverton. A short extension west from the south end to the new SR-154 (Bangerter Highway) was made in 2001, pending reconstruction by the state.
