I-70 Green River to Salina, Utah Becomes Latest Streach of Highway to Make Our Toughest Tows List.Back in November 2009, we did a segment called the “10 Toughest Tows in America,” which featured what we thought (at the time) were the most challenging stretches of road found along major U.S. highways. From least to most challenging, the list included Black Mountain (North Carolina), Monteagle Grade (Tennessee), The Grapevine (California), Emigrant Hill (Oregon), Union Pass (Arizona), Vail Pass (Colorado), Siskiyou Summit (Oregon), Wolf Creek Pass (Colorado), Loveland Pass (Colorado), and Atigun Pass (Alaska).
