Shifting Gears: Policies for a More Sustainable Highway System

The Environmental and Energy Study Institute (EESI) held a briefing focused on the past, present, and future of the U.S. highway system. Since the end of World War II, Congress has paved the way for thousands of miles of roadways to connect U.S. towns and cities and foster economic activity. But highways have divided us as much as they have connected us. Multilane roads have bisected communities, made it hard to get around without personal vehicles, and even prevented wildlife from moving within habitats. Highways have also come with an ever-increasing price tag, with $62 billion allocated to the Federal Highway Administration for maintenance, repair, and expansion in fiscal year 2025.

This briefing highlighted how the country’s highways can be maintained in the context of a changing climate, from increasing preparedness for extreme weather events to building out electric vehicle charging corridors. Panelists highlighted opportunities for federal policy to help relocate highways to reconnect communities, use cool pavement and climate-smart building materials, and manage toxic runoff from roads. The briefing also identified opportunities to optimize federal funding to improve the way the country’s highways connect people.
