[2] At 17 miles, approximately half-way through its route, Wyoming Highway 139 is intersected which acts as a spur into the community of Sand Draw.

Past Sand Draw, WYO 135 heads now more north-northwest toward Riverton as it passes through the Wind River Basin.

Nearing 34.5 miles, the western terminus of Wyoming Highway 136 (Gas Hills Road) is intersected which travels east towards the Gas Hills Mining District.

Just after meeting WYO 136, Highway 135 crosses the Little Wind River and reaches its northern terminus at Wyoming Highway 789 just south of Riverton.
