Rock Springs sits in the high desert of southwest Wyoming, along Bitter Creek and the Union Pacific line. I-80 runs east and west through the city, heading east toward Point of Rocks, Wamsutter and Rawlins and west toward Green River and Evanston. US 191 runs north as Elk Street toward Farson, Pinedale and Jackson, and south toward Flaming Gorge and Utah. Dewar Drive is the main commercial corridor, and Foothill Boulevard serves the newer neighborhoods on the hills. The city grew as a coal-mining and railroad town, and its older neighborhoods still climb the hills on either side of the creek.
For a mobile mechanic, Rock Springs is easy to cross, with most neighborhoods on hills and benches above the creek. The bigger challenge is I-80. It closes frequently in winter storms and high winds, especially east toward Rawlins and Laramie, stranding travelers in town. Hotels and truck stops along Dewar Drive and the interchanges fill up fast when the road closes, and many of those stranded vehicles need batteries, tires or belts. The roads to the oil and gas fields and the trona mines are long and rough, and many trucks come in with flat tires, broken suspension parts and worn brakes.
Southwest Wyoming Regional Airport sits east of the city, and its lot is a short drive away. Western Wyoming Community College, the county hospital and the Sweetwater County Events Complex bring steady traffic, and the trona mines and energy companies employ many shift workers. Wyoming's Big Show at the events complex each summer and boat traffic headed to Flaming Gorge add seasonal crowds.
