GLENWOOD CANYON INTERSTATE 70: A PRELIMINARY DESIGN PROCESS THAT WORKED

After nearly 20 years of study and 10 years of controversy and debate about the construction of an Interstate highway through picturesque Glenwood Canyon, the Colorado Department of Highways has developed and implemented a unique design development process that has won widespread public support for the project. The way seems to now be clear for closing one of the last gaps in the Colorado Interstate system. The open planning and design process allowed maximum public participation not only in the identification and preservation of critical environmental and recreational factors but also in the selection of technical design concepts for the highway. The design development process demonstrated how a politically and publicly controversial project received endorsement from virtually all elements of the public. The process is unique in that it used sports enthusiasts, naturalists, artists, and many lay persons to evaluate and decide on highly technical design issues and asked scientists, engineers, architects, and construction contractors to identify and demonstrate environmental, recreational, social, and aesthetic impacts. Modern design tools, including computer graphics, electronic survey instruments, and photo montages, were mixed with artists' drawings, sketches, models, and field mock-ups to suggest final alignments and grades, locate structures, pinpoint roadside facilities, and resolve safety issues. Completion of the design development process has culminated in the holding of a design public hearing, insurance of a design report that has been accepted by the vast majority of interested agencies and individuals, and design approval by the Federal Highway Administration. Use of the methodology developed in this process will provide an alternative to delays, repetitious studies, public and political controversy, increased costs, and litigation.
