County Road & Bridge Standards

The Summit County Engineering Department, in cooperation with the Road and Bridge Department, is responsible for the establishment and administration of the County’s Road and Bridge Standards, which are found in Chapter 5 of the Code.

These are standards for the design and construction of roads, bridges, recreational pathways and driveways, and for the classification and management of improvements to the existing County road system. Our standards are in general conformance with the following nationally and locally accepted agencies and laws:

• Colorado Revised Statutes (CRS)
• Colorado Department of Transportation (CDOT)
• American Association of State Highway Transportation Officials (AASHTO)
• Transportation Research Board (TRB)
• Institute of Transportation Engineers (ITE)
• Federal Highway Administration (FHWA)
• Colorado Asphalt Pavement Association (CAPA)

These regulations and standards are modified and amended in our Code as deemed appropriate by the County Engineer and the Road and Bridge director to preserve the integrity of the County’s roads and maintain a standard of safety for the users of Summit County's road system, while recognizing the unique challenges associated with design, construction and maintenance in the sensitive yet harsh high alpine environment.
