Complete collection guide available below. Canyon Echos newsletter debuted in April of 1976 as a citizen-directed/centered informational letter concerning the upcoming and ongoing efforts of construction in Glenwood Canyon. The newsletter was published and distributed by Colorado Department of Highways. Construction to begin extending Interstate 70 through Glenwood Canyon was first approved on February 20, 1976. Over the next decade, a myriad of construction and impact-mitigation would take place throughout the canyon to better accommodate an influx of traffic, visitors, and workers. Part of the project also included extending Interstate 70 west of Eagle, Colorado, creating a major highway through the entirety of the Eagle & Roaring Fork Valleys. Canyon Echos is evidence of a concerned citizenry throughout the project. A Citizens’ Advisory board and the Colorado Department of Transportation held meetings with the public to discuss the project and its many facets, including travel impacts, timeline, updates, changes, as well as the study and science that went into this expansive engineering project.
