Wyoming Highway 173
Wyoming Highway 173 (WYO 173) is a short  Wyoming state road located in  Hot Springs County south of Thermopolis. Route description

Wyoming Highway 173 begins its west end at US 20/WYO 789 just over a mile and a half south of Thermopolis. Named Buffalo Creek Road, Highway 173 travels southeasterly along the south bank of the Bighorn River. At 1.42 miles, WYO 173 crosses the river via the CQA Four Mile Bridge which is listed on the National Register of Historic Places. Two-tenths of a mile later WYO 173 reaches its end at County Route 31 (South Yellowstone Road). CR 31 continues another 1.6 miles south and returns to US 20/WYO 789. History

The original Four Mile Bridge, which carried Highway 173 over the Big Horn River, was completed in 1928 and was added to the National Register of Historic Places as part of a forty-bridge collection that illustrate steel truss construction. It was offered for sale by the Wyoming Highway Department in 1987 ahead of a planned replacement. The project to improve Highway 173 and replace the bridge was part of a 1984 agreement to eventually transfer control to Hot Springs County, but the county government declined to assume responsibility in 1993.
