About AASHTO

AASHTO is a nonprofit, nonpartisan association representing highway and transportation departments in the 50 states, the District of Columbia and Puerto Rico.

It represents all five transportation modes: air, highways, public transportation, rail and water. Its primary goal is to foster the development, operation and maintenance of an integrated national transportation system.

AASHTO's mission is to advocate transportation policies, provide technical services, demonstrate the contributions of transportation and facilitate institutional change.

Much of AASHTO's work is done by committees comprised of member department personnel who serve voluntarily. The Association provides a forum for consideration of transportation issues,and is frequently called upon by Congress to conduct surveys, provide data and testify on transportation legislation.

Through its policy development activities, member departments often address federal programs and provide guidance.
