Utah DOT Standard Specifications
UDOT publishes 119 documents in the BuildSpec Utah library: the standard specification book that governs materials, methods, measurement and payment on state-funded highway work, together with the standard drawings, design and construction manuals, and materials/testing references that are administered alongside it. 190 sections across 1 of those document are published here in full and read section by section — free, no download, no account.
Standard specifications are state-authored public documents. BuildSpec republishes them with the canonical UDOT source link on every page, and archives prior editions where UDOT still publishes them — a project bid in a prior year is still administered under the edition named in its contract. Always confirm the edition and supplement date named in your contract, and check UDOT’s own errata for revisions issued after printing.

Federal Standards
8 documentsMUTCD, ADA/PROWAG, NBIS, and other public-domain federal standards
The MUTCD defines the standards used by road managers nationwide to install and maintain traffic control devices on all public streets, highways, bikeways, and private roads open to public travel. It covers signs, signals, markings, and temporary traffic control. The 11th Edition was published in December 2023 with a compliance deadline of May 2026.
