Idaho Department Of Transportation

Idaho Department Of Transportation is a U.S. state government entity that receives federal transportation formula grants as the state's designated recipient and administrator, distributing funding to sub-recipients across Idaho's transportation network. The agency acts as a prime grant recipient (100% of awards) with no subcontractor role, delivering highway infrastructure, transit services, and safety programming on behalf of the Federal Highway Administration, Federal Transit Administration, and National Highway Traffic Safety Administration.

The agency's federal grant portfolio is overwhelmingly dominated by the Federal Highway Administration, which issued 18,512 awards (98% of award count) across multiple federal grant programs. Representative work includes a $841,000 Bridge Formula Program grant on August 31, 2026, to replace the Whiskey Jack Bridge over Boyer Slough in Bonner County; a $6.827 million Buses and Bus Facilities Formula grant on August 24, 2026, to purchase replacement and expansion buses for five rural and urban transit sub-recipients statewide; a $34.06 million Formula Grants for Rural Areas grant on July 15, 2026, supporting nine sub-recipients delivering operating assistance, preventive maintenance, and intercity bus services; and a $2.207 million Enhanced Mobility of Seniors and Individuals with Disabilities grant on July 15, 2026, providing transportation services for elderly and disabled persons in rural Idaho communities through four transit service sub-recipients plus four senior centers. Idaho DOT also received $1.08 million in Highway Safety Improvement Program funding on October 30, 2025, for behavioral safety initiatives, and $7.843 million on October 23, 2025, for statewide bridge inspections and load rating analysis. The National Highway Traffic Safety Administration awarded multiple safety-focused grants in October 2025, including $2.923 million for State and Community Highway Safety programming, $1.485 million for Impaired Driving Countermeasures, and $401,260 for traffic safety data system improvements.

Customer concentration sits entirely with the U.S. Department of Transportation and its modal administrations. The Federal Highway Administration accounts for the overwhelming majority (18,512 awards, $25,000 combined potential value, though the magnitude notation reflects a data anomaly in the source), followed by the Federal Transit Administration (174 awards) and National Highway Traffic Safety Administration (133 awards). All work is performed in Idaho, with administrative oversight at headquarters in Boise. The agency passes through Infrastructure Investment and Jobs Act formula funding under the Surface Transportation Block Grant Program (CFDA 20.287), Bridge Formula Program (CFDA 20.263), Highway Safety Improvement Program (CFDA 20.272), Railway-Highway Crossings Program (CFDA 20.285), and related categorical programs to metropolitan planning organizations, local governments, local transit operators, Idaho State Police, and federal land management partners including the Bureau of Land Management and U.S. Forest Service.

Activity has declined from a peak of 845 awards in 2022 to 126 awards year-to-date in 2026 (as of August 31), suggesting either a shift in award bundling practices at FHWA or reduced granularity in reporting. The recompete window shows 525 awards reaching ultimate completion within twenty-four months, representing substantial pipeline work across pavement preservation, bridge rehabilitation, pedestrian and bicycle infrastructure, transit capital, and safety programming. Idaho DOT's role is fundamentally administrative stewardship and direct execution of state-level transportation projects rather than competitive procurement; the agency does not compete for federal contract work through traditional vehicles or set-asides.
