Addison Airport Toll Tunnel (AATT)

 

The Addison Airport Toll Tunnel expands traffic capacity and eases congestion in the northern sector of Dallas and Addison by serving as an east-west route between the Dallas North Tollway and I-35E under the Addison Airport runway. The tunnel provides this through passage on Keller Springs Road, which once ended on either side of Addison Airport, as an alternative to Belt Line Road or Trinity Mills Road. It is a two-lane tunnel, approximately 1,600 feet in length, with a total roadway length of 3,700 feet. The tunnel opened to traffic in February 1999.
