Library Policies

Our Mission

To provide CDOT staff, consultants, local government, and Colorado residents timely access to materials related to planning, designing, constructing, maintaining and operating transportation facilities


We're open from 9 a.m. - 5 p.m., Monday through Thursday. Please call 303-757-9972 or email [email protected] before arriving.


There is a photocopy machine down the hall from the library. Customers should limit the number of copies to 20 pages and are expected to comply with national copyright laws.

Materials for Loan

Colorado residents and CDOT employees may borrow library materials for two weeks, with some exceptions. A core collection of reference materials is for library use only.

The career development and computer resource collections are reserved for CDOT employees.
