The D&RG built west from Pueblo reaching Cañon City in 1874. The line through the Royal Gorge reached Salida on May 20, 1880, and was pushed to Leadville later that same year. From Salida, the D&RG pushed west over the Continental Divide at the Marshall Pass and reached Gunnison on August 6, 1881. From Gunnison the line entered the Black Canyon of the Gunnison River passing the famous Curecanti Needle seen in their famous Scenic Line of the World Herald. The tracks left the increasingly difficult canyon at Cimmaron and passed over Cerro Summit, reaching Montrose on September 8, 1882. From Montrose, a line was laid north through Delta, reaching Grand Junction in March 1883. The line continued building west until reaching the D&RGW close to present day Green River which completed a narrow-gauge transcontinental link with the Rio Grande Western Railway to Salt Lake City, Utah.
