Celebrating a Century of Cooperation

The American Association of State Highway and Transportation Officials (AASHTO) will have its one hundredth anniversary on December 12, 2014. Since it was established, AASHTO has helped shape highway legislation, policy, and standards across the United States transportation network. It was founded in 1914 as an organization for state highway officials and has, since then, worked to improve transportation across the nation. AASHTO’s projects over the years includes developing a State-Federal partnership, numbering interstate highways to make them easily identifiable, standardizing highway signage, and helping states design their roads. AASHTO has spent the last century improving transportation in the United States and looks to the future to continue to do so.
