Route descriptionWyoming Highway 320 begins its south end at I-25 Business/US 87 Business (9th Street/Swanson Road) in Wheatland. From here WYO 320 heads north, intersecting East Laramie River Road at {{convert|4.6|mi|km}}, which can take you west to I-25 (exit 84). Highway 320 continues north till its end at US 26 in Dwyer[2][3] HistoryWyoming Highway 320 was originally designated in Fremont County along what is now Wyoming Highway 789 between Lander and Shoshoni between 1939 and 1950. It was originally US 320 between 1926 and 1938 but in 1939 was recommissioned as Wyoming Highway 320. In 1940, when US 287 and Wyoming Highway 287 were rerouted, Wyoming 320 was extended southwest to Lander. WYO 320 maintained this until 1950, when US 26 was commissioned. WYO 320 lasted until 1954, when Wyoming Highway 789 was commissioned, thereby replacing it. Additionally, The highway that currently carries Wyoming Highway 320 was originally part of US 87 and before that US 185 (US 185 between Cheyenne and Casper was decommissioned and replaced with US 87 in 1936)[4] Between 1956 and the 1980s, as more of Interstate 25 was completed, the original routing of US 87 was recommissioned on the Interstate 25 freeway.[5] Major intersections{{Jcttop|state=WY|county=Platte|location_ref=[6]}}{{WYint|location=Wheatland |mile=0.0 |road={{jct|state=WY|BL|25|US-Bus|87|dab1=Wheatland|dab2=Wheatland}} |notes=Southern terminus }}{{WYint |location=none |mile=4.6 |road=East Laramie River Road to {{jct|state=WY|I|25|US|87}} |notes=West to I-25/US 87 exit 84 }}{{WYint |location=none |mile=12.33 |road={{jct|state=WY|US|26}} |notes=Northern terminus }}{{Jctbtm}} References1. ^{{cite map |publisher=WYDOT |url=http://www.dot.state.wy.us/webdav/site/wydot/shared/Planning/Reference%20Marker%20Book.pdf |title=Wyoming Department of Transportation Reference Marker Book - November 2004 |accessdate=2011-03-31 |deadurl=yes |archiveurl=https://web.archive.org/web/20110717050844/http://www.dot.state.wy.us/webdav/site/wydot/shared/Planning/Reference%20Marker%20Book.pdf |archivedate=July 17, 2011}} 2. ^{{cite web|url=http://www.aaroads.com/west/wy-300.html|title=Wyoming Routes 300-399|publisher=AARoads}}{{sps|date=January 2017}} 3. ^{{Google maps|url=https://www.google.com/maps/dir/42.0676513,-104.9540218/42.2344288,-104.9730182/@42.1459942,-105.034764,11.5z|title=Wyoming Highway 320|accessdate=26 December 2016}} 4. ^{{cite web|url=http://www.aaroads.com/west/us-185_wy.html|title=U.S. Highway 185 (Decommissioned)|publisher=AARoads}}{{sps|date=January 2017}} 5. ^{{cite web|url=http://www.aaroads.com/west/us-087_wy.html|title=U.S. Highway 87|publisher=AARoads}}{{sps|date=January 2017}} 6. ^{{cite web|url=http://www2.census.gov/geo/pvs/bas/bas17maps/st56_wy/cou/|title=Wyoming Governmental Unit Reference Map|author=Geography Division|date=2016|website=|publisher=United States Census Bureau|accessdate=January 24, 2017}}
