Idaho Department Of Transportation

Idaho Department of Transportation, a U.S. state government entity and a division of the State of Idaho, receives federal formula grants from the Federal Highway Administration, Federal Transit Administration, and National Highway Traffic Safety Administration to deliver highway and bridge pavement preservation, safety improvements, multimodal transportation planning, and statewide transportation infrastructure assessment and maintenance services to Idaho's transportation network.

The agency operates exclusively as a prime recipient of federal grants—it holds no federal contract prime awards and pursues no contract work. Its federal grant footprint centers on transportation infrastructure preservation and public safety. Recent representative work includes a $5.53 million Surface Transportation Block Grant Program (CFDA 20.287) award to conduct a feasibility study on US 93 third river crossing options in Twin Falls; a $1.58 million Surface Transportation Block Grant award (CFDA 20.287) for pavement preservation improvements on Discovery Way in Boise, with ADA sidewalk compliance; a $420 thousand Highway Training & Education award (CFDA 20.294) to operate Idaho's Local Technical Assistance Program Center through August 2029, delivering training and technical support to local road agencies; and a $185.8 thousand Bridge Formula Program award (CFDA 20.263) for replacement of the Three Mile Creek Bridge in Idaho County. Other active work spans highway safety improvement programs (milling and overlay work, turn bay construction, rumble strips, dynamic curve warning systems), bridge inspection and load rating analysis, pavement condition surveys, traffic count collection, intelligent transportation system operations and maintenance (cameras, road weather sensors, electronic message signs), and planning coordination across Idaho's five metropolitan planning organizations.

The agency's customer concentration is extremely narrow and static. The Federal Highway Administration accounts for 18,357 of the 18,736 awards in the source data—97.97% by count—with a combined potential value of $25 thousand. The Federal Transit Administration and National Highway Traffic Safety Administration round out the active federal agency set, with 171 and 133 awards respectively. This concentration reflects Idaho DOT's statutory role as the state's designated recipient for federal transportation formula grants under the Infrastructure Investment and Jobs Act and prior authorization. The agency does not bid competitively for contracts and does not pursue work outside its transportation infrastructure management mandate.

Activity volume has declined year over year, dropping from 835 awards in 2022 to 52 awards in the calendar year through June 2026—a pattern consistent with the shift from discrete project-by-project awards to multi-year formula grant cycles that bundle funding across multiple activity types and completion dates. Within the next twenty-four months, 343 awards reach ultimate completion date, signaling significant recompete and renewal activity across the portfolio. The agency's role is administrative steward and project executor for federal transportation funding, not a competitive vendor. Federal grants flow through Idaho DOT to sub-recipients including metropolitan planning organizations (COMPASS, Bonneville, Kootenai, Lewis and Clark Valley, Missoula Valley MPOs), local transit operators (Lewiston Transit, Valley Regional Transit, Treasure Valley Transit, Greater Idaho Falls Transit), Idaho State Police (for work zone patrols), local governments, and federal land management partners including the Bureau of Land Management and U.S. Forest Service. The agency also acts as pass-through recipient for the State and Community Highway Safety Program (CFDA 20.600), distributing behavioral highway safety funding to local law enforcement and community safety partners. Recent cooperative agreements include a five-year Good Neighbor Authority pact with the BLM for noxious weed management and hazardous tree removal across ten counties in District 3, and a $247 thousand Federal Aviation Administration project grant to update Idaho's Statewide Airport System Plan. As a U.S. government entity, Idaho Department of Transportation is not a vendor to federal contractors and does not sub on prime contract awards; it is a grantor and sub-grantee distributor within the federal transportation assistance framework.
