The Lewisville Lake Toll Bridge is a 1.7 mile tied arch bridge crossing Lewisville Lake in Denton County, Texas, USA. The North Texas Tollway Authority worked cooperatively with Denton County to plan and design a toll bridge across the northwestern arm of Lewisville Lake. The four-lane toll bridge connects Swisher Road in Lake Dallas to Eldorado Parkway in Little Elm, Texas. The Lewisville Lake Corridor is approximately 13.8 miles long and is divided into eight sections constructed by Denton County, NTTA, TxDOT, Little Elm, and Frisco, Texas. The bridge is the second longest bridge in the North Texas area, behind the Texas State Highway 66 bridge over Lake Ray Hubbard between Rowlett and Rockwall approximately 30 miles to the southeast. Motorists in the fastest growing areas of Denton County and the Dallas-Fort Worth metroplex are able to travel on a new connection between Interstate 35E and the Dallas North Tollway, eliminating the circuitous routes currently required around Lewisville Lake. The conceptual design of the project entailed eight sections that, together, total. Only the bridge over the lake is tolled. The bridge is above the normal water level of 522ft elevation, to allow clearance for sailboats. The "signature" of the bridge, according to the NTTA, is the steel section with arches that rise to above the road deck. The surfaces of this section are lighted with LEDs at night to make the structure visible from the surrounding shores of the lake. The project opened to vehicular traffic on August 1, 2009 after a charity run and walk across the bridge. The NTTA stated that occasion was the only time pedestrians will ever be allowed to cross the bridge. The NTTA funded and constructed the toll bridge while the cities along the corridor, Denton County and Texas Department of Transportation funded improvements to the roadways approaching the bridge. The NTTA toll across the bridge section is $1.32 for TollTag customers and $1.98 for ZipCash drivers.
History
A bridge previously connected Little Elm and Lake Dallas, but 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.
