Near the top of the Rocky Mountains west of Denver, as I-70 and US 6 approach the Continental Divide, the historic mining towns of Georgetown and Silver Plume sit separated by just two miles. However, it is an exceedingly tough two miles. So tough that the first railroad crossing, completed in 1884, became an early tourist attraction for its "loop" design, where the track makes a full 360 and doubles over itself, and Devil's Gate High Bridge, considered an engineering marvel at the time. The high slopes of the canyon following Clear Creek west from Georgetown create a transportation barrier. A wagon road between the two towns had interest as early as 1869 to connect Georgetown with mines to the west (14), but it was not completed until 1882 (5), and even then was regarded as dangerous (4).
