 North of Mojave the alignments of State Routes 14 and 89, and U.S. Route 395 have not significantly changed since first paved, and are called El Camino Sierra. Significant portions have been upgraded to a divided highway; however, most of the upgrades used the same alignment as the old two lane road. The highway cuts across Red Rock Canyon State Park to follow a series of valleys along the crest of the Sierra Nevada. While traversing the Owens Valley, the Sierra Highway passes Mount Whitney, the highest point in the contiguous United States, 10,000 feet (3,000 m) above the highway. As of 2009, the only other signed section of Sierra Highway is a portion of U.S. 395 past the separation with U.S. 6 in Bishop.
