WYDOT: 50 mph on 22 The Wyoming Department of Transportation, Teton County and its residents have been debating what speed is right for a stretch of Highway 22. On Thursday, WYDOT announced a number thatâs higher than the countyâs ask but lower than what the state agency recommended this spring. That number is 50 miles per hour, all year long. Thatâs the midpoint between the 45 mph year-round limit county commissioners requested and the 55 mph limit WYDOT initially said was appropriate. The department plans to implement the new limit on the stretch of Highway 22 that runs from Spring Gulch Road to Emily Stevens Park on July 1 âor earlier.â
