The Transportation Construction Coalition (TCC) is commemorating the upcoming 70th anniversary of the Interstate Highway System and highlighting the need for Congress to pass a new surface transportation authorisation and modernise the network.
The interstate system, which spans nearly 80,000km, remains essential to moving people and goods safely and efficiently across the country. By facilitating the reliable movement of goods at scale, the Interstate Highway System helps keep costs of essential goods down, improving affordability for families and businesses. Adequate maintenance of existing links is as essential as constructing new routes.
“From supporting supply chains to connecting communities, America’s Interstate Highway System has powered economic growth and opportunity in every region of the country for decades,” the coalition said. “As this system ages and demand continues to grow, sustained federal investment through a new surface transportation reauthorisation is essential to ensure it remains safe, reliable, and efficient for the millions of Americans who depend on it every day.”
“Congress must pass the next surface transportation reauthorisation and reinforce the federal commitment that created the interstate system by investing in key initiatives such as major bridge improvements, freight movement projects, and road and workzone safety programs,” the coalition continued. “Advancing a new surface transportation reauthorisation bill by September 30 will support continued economic growth for communities nationwide and keep America moving.”
Interstate 10 serves as a vital Gulf Coast corridor, connecting major economic hubs from Texas to Louisiana and supporting one of the nation’s most important freight routes. Investments along this corridor, including the Calcasieu River Bridge, help strengthen supply chains, reduce congestion, and keep goods moving efficiently across the region while improving safety for regional drivers.
Interstate 70 connects communities and commerce from the Rocky Mountains through the Midwest, serving as one of the country’s most critical east–west freight corridors. Federal funding to modernize key segments of I-70 ensures it continues to meet growing demand, preventing freight bottlenecks and protecting affordability for millions of Americans.
Interstate 90 is a critical artery for New York’s economy, linking upstate communities to national and international markets while supporting freight movement, tourism, and regional development. Continued investment in I-90 and the Castleton-on-Hudson Bridge, which carries drivers over the Hudson River, drives economic growth, enhances connectivity, and sustains long-term economic growth and opportunity across the state.
