Route

The pass is traversed by the Million Dollar Highway, U.S. Highway 550 south of Silverton, which is part of the San Juan Skyway Scenic Byway. While the north side is fairly gentle, the descent on the south side is very steep (6.5%), and has a runaway truck ramp for trucks that lose control. It is basically downhill the entire way to Durango.
