UDOT Library
Library Services
Employees can access a growing digital library featuring mostly AASHTO publications, hosted on UDOT’s Learning Portal. A small hard-copy collection of UDOT design and construction standards and legal reference books is housed in the Lester Wire Memorial Library at UDOT headquarters. Expanded access to materials is available through Interlibrary Loan, in partnership with the Utah State Library and other lending libraries across the US. This service allows us to receive digital copies of journal articles within a day or two of request. Finally, as part of UDOT’s Research and Innovation Division, employees may ask the library for assistance with literature searches.
A variety of free publication sources are linked in the Publications section below.

Publications
Digital Library
The digital library is comprised mainly of complimentary publications released by AASHTO along with those we have purchased. You can browse the AASHTO Bookstore for other available publications. If you need an AASHTO publication that is not in our digital library, please contact the librarian to see if funds are available to buy it. Making one purchase for the library instead of multiple purchases of the same item for different groups in UDOT saves money. Join the AASHTO publications mailing list to receive their catalog and alerts about new releases.
We also have a few UDOT, FHWA (i.e., the current MUTCD), ITE, and TRB publications available in the digital library.
