We've Moved!

CDOT has moved its central and Denver Metro area headquarters:

2829 W. Howard Pl.
Denver 80204

Please update this address change in all documents that still have the old CDOT address (4201 E. Arkansas Ave. Denver 80224) All documents with the old address are still official and good to use. Thank you.

Our branch is responsible for the specifications, test procedures, and associated testing of materials to ensure compliance with CDOT standards and Federal Highway Administration (FHWA) regulations. This includes bulletins, manuals, policies, procedures, product approval and testing—as listed in this site's menu.

The branch also provides program services, which include:
