U.S. Route 50 (US 50) is a part of the U.S. Highway System that travels from West Sacramento, California, to Ocean City, Maryland. In the U.S. state of Colorado, US 50 is a major highway crossing through the lower midsection of the state. It connects the Western Slope with the lower Front Range. The highway serves the areas of Pueblo and Grand Junction as well as many other smaller areas along its corridor. The long-term project to widen the highway from two lanes to a four lane expressway between Grand Junction and Montrose was completed in January 2005. Only about 25% of the remainder of US 50 in Colorado is four lane highway.
