Happy 70th Birthday, U.S. Interstate System! 🥳 🛣️

On this day in 1956, President Dwight D. Eisenhower signed the Federal-Aid Highway Act, officially ushering in the Interstate era.

From the very first project in Missouri to the massive network we rely on today, we are proud to celebrate seven decades of progress, connectivity, and innovation.
