The Fixing America's Surface Transportation (FAST) Act, enacted in December 2015, authorized the establishment of a Regional Infrastructure Accelerators (RIA) Demonstration Program to assist entities in developing improved infrastructure priorities and financing strategies for the accelerated development of a project that is eligible for funding under the Transportation Infrastructure Finance and Innovation Act (TIFIA) Program under Chapter 6 of Title 23, United States Code.

The Further Consolidated Appropriations Act, 2020, enacted on December 20, 2019, appropriated $5 million for this Program.

On November 29, 2023, the Bureau held the first-ever RIA Summit in College Park, Maryland. The Summit convened over 70 people, including representatives from 19 of the 21 RIA grant awardees, the Bureau, University of Maryland staff, Global Infrastructure Investor Association staff, and USDOT operating administration staff. To learn more about the event, please read the RIA Summit Summary or watch a video.
