The US Department of Transportation has published the list of local authorities awarded nearly $1 billion in grants under the fiscal year 2025 Safe Streets and Roads for All (SS4A) programme.

The $982 million in funding will be distributed among hundreds of regional, local, and Tribal jurisdictions to support projects ranging from “quick-build” safety improvements to large-scale construction.

The Safe Streets and Roads for All (SS4A) programme is a discretionary grant initiative designed to support the “Vision Zero” goal of eliminating roadway deaths and serious injuries.

Unlike many federal transportation programs that flow through state agencies, SS4A provides direct funding to local governments to develop comprehensive safety action plans and implement evidence-based projects.

The programme follows a “Safe System Approach,” which emphasises redundant safety layers—such as better road design, lower speeds, and enhanced post-crash care—to account for human error and reduce the severity of accidents for all road users, including pedestrians and cyclists.

Among notable awards in the 2025 cycle is a pilot programme in Huntsville, Alabama, which secured funding to deploy AI-based adaptive signal timing along the Meridian Street corridor. This intelligent transportation system (ITS) uses real-time data and machine learning to adjust traffic signals during peak hours, reducing the stop-and-go congestion that often leads to rear-end collisions and pedestrian risks. Other significant grants include a $21 million award for Huntsville to construct a cable-suspended pedestrian and bicycle bridge over Governors Drive, and substantial safety upgrades for school zones in the Matanuska-Susitna Borough of Alaska.

The 2025 awards show an increasing federal emphasis on technology-driven solutions to manage urban traffic density. By prioritising projects that integrate artificial intelligence and “smart” infrastructure, the USDOT aims to prove that digital optimisation can be as effective as traditional asphalt expansion in saving lives. With this round of funding, the SS4A programme has now reached more than 1,600 communities across the United States since its inception in 2022, forming the backbone of the National Roadway Safety Strategy.
