The TIDP receives $550 million over five years, or $110 million annually, and funds various transportation and highway research endeavors. The program has existed since 2013, and was continued by the FAST Act in 2016 and the IIJA in 2021.
ADCMS, which pulls from the TIDP’s pot, has $85 million over the next five years, with the current $34 million allocated in FY 2022 and 2023. This means further aid is capped until FY 2024, at which point the program will offer a combined $17 million in grants for new projects each year.
