Lewisville Lake Toll Bridge
The Lewisville Lake Toll Bridge (LLTB) is a 1.7-mile (2.7 km) tied arch bridge crossing Lewisville Lake in Denton County, Texas, USA. Operated by North Texas Tollway Authority (NTTA), the four-lane toll bridge connects Swisher Road in Lake Dallas to Eldorado Parkway in Little Elm. It is one segment of the 13-mile (21 km) Lewisville Lake Corridor, which connects Interstate 35E and Dallas North Tollway.

The bridge is the second-longest bridge in the North Texas area. Only the State Highway 66 bridge over Lake Ray Hubbard, which connects Rowlett and Rockwall, is longer.

Toll rates across the bridge are $1.32 for TollTag customers and $1.98 for ZipCash drivers.

Design

Bridge archway in April 2010

The bridge is 60 feet (18 m) above the normal water level to allow clearance for sailboats.

At the center of the bridge is a 360-foot (110 m) steel arch that rises 60 feet (18 m) above the road deck. The arch's design resembles the arch on the Pennybacker Bridge in Austin. At night, the arch is illuminated using LEDs, making the structure visible from the surrounding shores of the lake.

History

A bridge previously connected Little Elm and Lake Dallas, but it was removed in the 1950s when the United States Army Corps of Engineers expanded Lewisville Lake. The old bridge provided a vital transportation link between Lake Dallas and Little Elm.

On August 1, 2009, a 5K charity run crossing the completed bridge was held. The run, which served as a fundraiser for local food banks, was the only time pedestrians will ever be allowed to cross the bridge. The bridge opened to vehicular traffic after the event was completed.

Project Costs

  • Project Cost Estimate: $220 million (entire corridor)
  • Estimated NTTA Cost: $122 million (toll bridge only)

Corridor

The Lewisville Lake Corridor is approximately 13.8 miles long and is divided into eight sections constructed by Denton County, NTTA, the Texas Department of Transportation, Little Elm, and Frisco. NTTA funded and constructed the toll bridge, while the other partners funded improvements to the roadways approaching the bridge. Only the bridge itself is tolled.
