The Colorado Department of Transportation (CDOT) makes these documents available on an "as is basis". All warranties and representations of any kind with regard to said documents are disclaimed, including the implied warranties of merchantability and fitness for a particular use. Under no circumstances will CDOT, or any of its officers or employees be liable for any consequential, incident, special or exemplary damages even if appraised of the likelihood of such damages occurring.

Standard Plans

Standard Plans are separated into two categories; Miscellaneous (M-Standards) and Safety (S-Standards). The latest published version of the M&S Standard Plans is dated July 31, 2019. S-Standards contain details common for safety, such as delineators, lighting, signs, sign supports, traffic signals and accessories, pavement markings, and traffic control. Electronic files for the 2019 S-Standard Plans are available in English units only. Please visit the M-Standards page for details relating to guardrail, box culverts, roadway, super-elevation, and pavement.
