Colorado's Early Roads

If you have ever crossed the Arkansas River in Pueblo, Colorado, you are crossing over one of Colorado's first road projects dating back to the 1860s. By the 1880s Colorado gave the green light for Otto Mears to begin building his "Million Dollar Highway" through the San Juan Mountains. Otto's project was one of Colorado's first highways but it was still a dirt road. Colorado's first paved road wasn't far behind.

Colorado's First Paved Roads

It's an interesting coincidence that the art of pouring concrete roads in Colorado would begin in a place that would later be known as one of Colorado's popular art districts in the Denver Metro. Colorado's Santa Fe Drive, also known as U.S Route 85, ran from Littleton to Denver. The road was built as part of the Federal Highway Act of 1916 which generated $73,939 to build the first paved road in Colorado just 2 years later.

Colorado's Santa Fe Drive Today

Here is what Colorado's first paved road looks like today as you drive from Littleton to Denver. Like the rest of Colorado's original six federally funded highways, these roads were built by prison inmates between 1905 and 1926. Colorado's original 1916 highway plan included:

  • US 85: Denver-Littleton, $73,939.
  • 1-25/US 85: Pueblo-Trinidad, $261,191
  • US 24: Granite-Twin Lakes, $37,089
  • SH 13:  Rifle-Meeker, $79,082
  • SH 145: Placerville-Norwood, $7,408
  • US 287/385: Lamar-Springfield, $10,030
