The Benefits of Membership

TDA instantly connects you to a statewide network of transportation leaders. You’ll have the chance to participate in initiatives that strengthen an integrated transportation system throughout Wisconsin.

TDA provides you with timely, insightful publications that do more than summarize transportation developments. The publications explore and explain how these developments affect you, your business and your community.

TDA is your one-stop shop for information and services related to Wisconsin transportation. Need a speaker? In search of a study? TDA’s full-time staff provides expert membership support.

TDA’s members participate in annual events and help inform state and federal legislators on transportation issues. TDA members play a key role in guiding a more balanced and effective transportation network on behalf of everyone in Wisconsin.
