AASHTO Subcommittees

AASHTO Subcommittees are specialized groups within the American Association of State Highway and Transportation Officials, each focused on specific aspects of transportation—such as highways, bridges, safety, or environmental issues. They bring together experts from various states to develop standards, share best practices, and coordinate policies. These subcommittees help ensure that transportation projects are safe, efficient, and consistent across the country. By working collaboratively, they support the overall mission of improving transportation systems for all users.
