Traffic Control, Standards & Specification Services

S-Standards & Specifications 

The use of Colorado Department of Transportation standards are required to ensure that all transportation projects are clear, concise, correct, complete and in compliance with Federal Highway Administration (FHWA).

Signing & Pavement Markings 

All signs designed and placed on Colorado State highways must conform to the requirements as outlined in the CDOT Sign Design manual. Colorado Supplement to the MUTCD's Standard Highway Signs, Colorado Special signing cases, and guide sign examples are available for download.

Work Zone Safety 

With all roadway construction comes equipment, works, and daily changes in the road and alignment that may impact the safety and operations of the roads you may travel. As a result, it is critical that we all do a part in creating a safer work zone.

Traffic Documents & Publications 

The design of state highways also rely on traffic guidelines, manuals, and brochures as supplement for the additional elements that may not be covered through standard drawings.
