Montrose is the Home Rule Municipality that is the county seat and the most populous municipality of Montrose County, Colorado, United States. The city population was 19,132 at the 2010 United States Census. The main road that leads in and out of Montrose is U.S. Highway 50. The town is located in cardinal-western Colorado, in the upper Uncompahgre Valley and is an economic, labor, and transportation waypoint for the surrounding recreation industry. It is also the home of a few major engineering projects, namely the Gunnison Tunnel.
Montrose was incorporated on May 2, 1882 and named after Sir Walter Scott's novel A Legend of Montrose by Oliver D. "Pappy" Loutzenhizer and Joseph Selig. The Denver & Rio Grande railroad was built west toward Grand Junction and reached Montrose later in 1882, and the town became an important regional shipping center. A branch railroad line served the mineral-rich San Juan Mountains to the south.
In 1909 the U.S. government completed construction of the Gunnison Tunnel, which provided irrigation water from the Gunnison River in the Black Canyon to the Uncompahgre Valley, helping turn Montrose into an agricultural hub. The Uncompahgre Project is one of the oldest of those in the area by the U.S. Bureau of Reclamation.
