First off, always check road conditions during the winter months in Nevada! If all looks good weather-wise, State Route 722 is a beautiful drive with great views of snow-covered peaks.
722 veers off of US Highway 50 near the roadhouse at Middlegate. It then crosses two summits: Eastgate at 5,110 feet, and Carroll Summit at 7,492 feet. It reunites with US Highway 50 just west of Austin. The highway is the old route of US Highway 50 and previously the Lincoln Highway. The US 50 designation was removed in favor of the new route that traverses the Desatoya Mountains via New Pass Summit, which is 1,100 feet lower with easier inclines on both sides.
