Patricia Hayes’s Traffic and Safety Engineering experience spans 30 years with the Colorado Department of Transportation (CDOT), in the design, preparation and oversight of traffic control plans. She served 13 years in the CDOT headquarters Staff Traffic Branch before transferring to CDOT Region 1 (formerly Region 6) where she led one of two traffic design squads under the Region Operations Engineer. Patricia later assumed the duties of Assistant Access Manager and then Access Manager. Her work resulted in hundreds of successful developments and modifications to businesses along state highways, long-range access control plans, and a multitude of corridor, traffic and environmental studies.  

 Patricia’s expertise in CDOT design details and functions includes: signing and signal plans, overhead sign structures, striping, delineation, roadside safety treatments and lighting. She has reviewed and approved MHTs (Methods of Handling Traffic) and CTCPs (Construction Traffic Control Plans), as well as specifications, contracts, permits, and work orders for local agencies. Patricia assisted in the selection process of roundabout designs, TREX construction plan review, and light-rail committees for agreements, contracts and specifications, in addition to phasing for plans on freeways, expressways, and rural highways. 

Patricia has also served on committees for the environmental planning processes, IGAs (Inter-Governmental Agreements), and defining Access and Traffic control plans. Throughout her career, she collaborated with consultants, government agency representatives, various stakeholders, and nearly every section of CDOT, resulting in a unique understanding of the CDOT Region and Headquarters office structures, as well as the network of CDOT personnel statewide. 

Patricia’s career was shaped by her curiosity, tenacious ambition, and by the strong support she received at CDOT. Few women existed in the technical and professional engineering field when she first started with CDOT. She was empowered by this challenging yet nurturing environment, and advanced because of her motivations for success. With 30 years of experience in traffic engineering, Patricia would now like to help others succeed on CDOT projects.

Patricia is available for consulting through the Denver Metro SBDC in downtown Denver, as well as by virtual appointment statewide.
