road dips to the south slightly and, following two SPUIs at Redwood Road (SR-68) and 900 West, the freeway terminates at the Spaghetti Bowl interchange, giving eastbound motorists on SR-201 the option of continuing to I-15, I-80, 1300 South and 900 South. However, an eastbound traveler wanting to continue on the surface portion of SR-201 to State Street must exit on 900 West, head north briefly and then turn eastbound on 2100 South; a westbound traveler on 2100 South wishing to connect to the freeway must take an on-ramp from the surface street just before 900 West. Prior to 1997, this connection was direct. Now on the four-lane 2100 South, a secondary surface street, the route runs along the Salt Lake City-South Salt Lake border. State maintenance of 2100 South ends at the intersection of State Street (US-89). History State Route 201 is one of the original highways through the Salt Lake Valley. Signs along the route claim the path of the highway to be the historical route of the California Trail, Pony Express and Lincoln Highway. While signed as the route of the California Trail, modern 2100 South is a less common branch called Hastings Cutoff that became infamous because of the Donner Party. The Lincoln Highway, generally derived from the route of the Pony Express across Utah, was routed on 2100 South. However, no modern highway exactly follows the route of the Pony Express west of Salt Lake City. SR-201 is one of a few auto-tour routes that approximates the Pony Express trail, which actually ran south of the road. In the 1910s, 2100 South in Salt Lake County became an unnumbered state highway. In 1919, when the state legislature redefined the state road system to include only a short list given in the law and any federal aid projects, 2100 South east of State Street remained as a portion of the Lincoln Highway. In 1926, 2100 South became part of US-40, following the creation of the United States Numbered Highway system. By 1937, 2100 South west of 9180 West was assigned to US-50, US-40 now turning northward toward Downtown Salt Lake City. This created two signed highways over 2100 South: US-40 east of US-91 and US-50 east of 9200 West (US-50 traveled west on 3500 South through Salt Lake City from US-91 to 2100 South in Magna, whereas US-40 turned from eastbound 2100 South to northbound State
