state highway in theU.S. state ofUtah , connecting the Rush andUtah Valley s.Route description
SR-73 begins at an intersection with SR-36 in the
Rush Valley , northeast of the town of the same name. It heads southeasterly, climbing slightly to the edge of theOquirrh Mountains , and then curving between the south end of the range and theDeseret Chemical Depot . When the highway reachesFivemile Pass , awind gap between the Oquirrh Mountains andThorpe Hills , it curves northeast, joining the historicCentral Overland Trail (Pony Express route) through the pass and descending into the Cedar Valley. At Fairfield, SR-73 curves north, while the old trail continues its northeasterly path as Lehi-Fairfield Road. The route again curves northeast at Cedar Fort, crossing the valley and passing between theLake Mountains andTraverse Mountains . The final segment is within theUtah Valley , as SR-73 heads east across the Jordan River and into Lehi, where it serves as that city's Main Street before ending at US-89.Google Maps street maps andUSGS topographic map s, accessed July 2008 via [http://mapper.acme.com/ ACME Mapper] ]History
The state legislature defined State Route 73 in 1933, running from SR-68 (created in 1931 [cite UTSR law|year=1931|quote=(68) From junction with route 67 southerly via Redwood road in Salt Lake county to Lehi in Utah county.] ) 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 formerFairfield Branch of theUnion Pacific Railroad . [cite UTSR law|year=1933|chapter=29|quote=(73) From Jordan Bridge on state highway number 68 southwesterly via Cedar Fort, Fairfield and Topliffe to connect with state highway number 36.] Two years later, the portion west of Fairfield was dropped, in favor of a routing south from Fairfield to SR-26 (now US-6) near Eureka. [cite UTSR law|year=1935|quote=Route 73. From Jordan Bridge on state highway number 68 southwesterly via Cedar Fort and Fairfield to Eureka.] State Route 180 was also created in 1935, beginning at SR-36 south of Stockton and heading east throughOphir Canyon to Ophir and southeast through theOquirrh Mountains to Mercur. [cite UTSR law|year=1935|quote=Route 180. From a point on route 36 south of Stockton southeasterly via Ophir to Mercur.] State Route 202 was defined in 1939 as an eastern approach to Mercur, splitting off SR-73 north of Fairfield and climbingManning Canyon , [cite UTSR law|year=1939|quote=Route 202. From a point on route 73 near Fairfield westerly to Mercur.] 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 downMercur Canyon to SR-180 replacing it. [cite UTSR law|year=1941|chapter=34|quote=Route 180. From a point on route 36 south of Stockton southeasterly to Ophir." "Route 202. From a point on route 73 near Fairfield westerly via Mercur to route 180.]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 theDeseret Chemical Depot north to SR-73 near its west end, constructed withfederal aid in 1942,Utah Department of Transportation , [http://www.udot.utah.gov/main/f?p=100:pg:5285268476414239680:::1:T,V:1348, Highway Resolutions] : PDFlink|1= [http://www.udot.utah.gov/main/uconowner.gf?n=200609191546571 Route 198] |2=3.00 MB, updated November 2007, accessed May 2008] was numbered State Route 198. [cite UTSR law|year=1945|quote=Route 73. From route 68 west of Lehi southwesterly via Cedar Fort and Rock Quarry Point to Fairfield station, thence westerly across Houeholder's Flat, thence northwesterly via Chemical Storage Depot to route 36 northeast of St. John station." "Route 180. From route 73 northeasterly to Ophir." "Route 191. From route 73 south of Cedar Fort southerly to Fairfield." "Route 198. From route 73 south to north entrance of Chemical Storage Depot." "Route 202. From route 73 northeasterly to Mercur.] In short, SR-73 now connected SR-36 to SR-68, with four spurs from west to east: SR-198 to the chemical depot, SR-180 to Ophir, SR-202 to Mercur, and SR-191 to Fairfield.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. [cite UTSR law|year=1953]

Due to a southerly extension of SR-68 in 1960, splitting at the SR-73 intersection, the portion of SR-68 into Lehi was renumbered as an extension of SR-73, which gained its current length at that time.Major intersections
