The Fiscal Year (FY) 2023 Omnibus Appropriations bill that passed on December 23, 2022, includes funding to kick-start the Active Transportation Infrastructure Investment Program (ATIIP).

The bill includes $45 million for the program. While short of the $200 million ATIIP authorization in the Bipartisan Infrastructure Law and the $500 million that RTC and Congressional champions called for in proposing the Connecting America’s Active Transportation System Act, this funding is critical to launch the program and demonstrate that connectivity investments are in high demand across the country.

Now that it is funded, the program will establish competitive grants that strategically invest in projects that connect active transportation networks and spines, accelerating local and regional plans to create safe and convenient walking and biking routes to everyday destinations and to fill gaps in trails between communities.

This unique program will enable communities to build from existing infrastructure for walking and biking to safely connect people to the destinations they travel to routinely, while also creating opportunities for sustainable transportation and recreation.

The US Department of Transportation has not yet released information on the application timeline or directions on how to apply, but RTC will continue to update this page as information is available.


Advocating for FY24 ATIIP FUNDING

RTC is now advocating for funding for the program in the Fiscal Year 2024. USDOT is developing its budget proposal for FY24, and RTC sent a sign-on letter with the support of 24 organizations to the administration requesting this funding. We will continue to make the case for the program to key decisionmakers ultimately responsible for the development of the next federal budget with a goal to fully fund the program.
