History
The state legislature defined State Route 73 in 1933, running from SR-68 (created in 1931) west of Lehi southwest via Cedar Fort, Fairfield and Topliff to SR-36. Up until Fivemile Pass, beyond Fairfield, this followed the present route of SR-73, but at Fivemile Pass the route curved southwesterly, generally following the former Fairfield Branch of the Union Pacific Railroad
The Union Pacific Railroad , legally Union Pacific Railroad Company and often called simply Union Pacific, is a freight-hauling railroad that operates 8,300 locomotives over routes in 23 U.S. states west of Chicago and New Orleans. Union Paci ...

to Mercur. State Route 202 was defined in 1939 as an eastern approach to Mercur, splitting off SR-73 north of Fairfield and climbing Manning Canyon, and in 1941 the portion of SR-180 between Ophir and Mercur was removed from the state highway system, with an extension of SR-202 west down Mercur Canyon to SR-180 replacing it.
SR-73 was realigned again in 1945, turning southwest between Cedar Fort and Fairfield, absorbing the beginning of SR-202, and continuing southwest to a point between Fairfield and Fivemile Pass. The remainder of the route followed its present alignment to SR-36, replacing the portions of SR-202 and SR-180 that lay outside the canyons in the Rush Valley

. The part of former SR-73 from Fairfield north to the junction south of Cedar Fort became State Route 191, while the part south of Fairfield was given to the county. SR-202 was cut back to only the portion in Mercur Canyon, with the Manning Canyon piece dropped. Finally, a connection from the Deseret Chemical Depot

Over the next two decades, all four spurs disappeared. The first two to go were SR-191 and SR-202, both eliminated in 1953. This completely removed Mercur from the state highway system, but Fairfield was kept by moving SR-73 to its current alignment through that community.Utah Department of Transportation

In 2011, in conjunction with the building of the Pioneer Crossing ( SR-145) extension, the segment on Crossroads Boulevard between SR-68 and 850 East in Lehi was removed from the state highway system, which made SR-73 a discontinuous route. The route was further relinquished in 2015, with the segment between SR-68 and SR-145 turned back to the city of ]Saratoga Springs
