Wyoming Highway 193 (WYO 193) is a 6.19-mile-long (9.96 km) north–south WyomingState Road that runs through southern Sheridan County and the extreme northern part of Johnson County and serves the community of Story.
In the late 1990s, a short section of US 87/WYO 344 between Interstate 90 north of Buffalo and Sheridan, at the Massacre Hill Historic Site, had been permanently closed due to recurring landslides.[3] According to the Wyoming Department of Transportation, the stretch of roadway has ongoing and costly maintenance problems, with the most recent landslides closing the roadway as of the Spring of 1998.[3] Because repairing the roadway could potentially damage the historic site, WYDOT recommends that through traffic use either Interstate 90 or Wyoming 193 as an alternate route.[3]
As a result of the landslide on US 87, Wyoming petitioned the American Association of State Highway and Transportation Officials (or AASHTO) to reroute US 87 over Highway 193 in the late 1990s. However, this was denied. Consequently, a detour for US 87 follows WYO 193 since it is unlikely that US 87 will be reconstructed at its current location.[5]
