Welcome to the new CDOT Research Library


CDOT Research Library Online Catalog

The CDOT Research Library makes available relevant and authoritative information resources related to construction, planning, design, environmental impact assessment, engineering, research, policy, and many more. This includes manuals, brochures, technical reports, standards, studies, and materials for loan.

Items are still being added to the library catalog, so it currently contains about half of the items in the library collection.  

The library catalog doesn't contain everything posted on the CDOT website. 
Use CDOT's search box at the top right corner of the page to search the entire website.
