The 1.7-mile bridge connects I-35E at Swisher Road to the Dallas North Tollway at Eldorado Parkway. In addition to providing an east-west connection to destinations in Denton County, the Lewisville Lake Toll Bridge serves as a visually unique landmark. It features a signature arch, spanning 360 feet near the center of the bridge. The LLTB opened to traffic in 2009.
