2020 CDOT Lighting Design Guide

The CDOT Lighting Design Guidelines represent the current recommended practices for roadway lighting and includes criteria for typical applications found in the State of Colorado. This guideline should be used for all CDOT owned and maintained lighting installations. For lighting projects with CDOT oversight, the designer should first consider the lighting requirements, both criteria and equipment, of the entity that will be owning and maintaining the lighting equipment. If this guide is more stringent than the controlling entity, this guide should be followed. For instance, if the entity has high or no glare criteria, the design should follow this guide for minimizing glare. This design guide may also be used in the absence of lighting criteria or lighting equipment requirements.
