Lewisville Lake Toll Bridge Takes Shape in Denton County Construction is well under way for the Lewisville Lake Toll Bridge (LLTB) in Denton County. Nearing 75 percent completion, the LLTB is expected to open to traffic in the third quarter of 2009. Once finished, the LLTB corridor will open a new east-west connection between Interstate 35E and the Dallas North Tollway, providing added mobility options for area residents.
The NTTA is working cooperatively with Denton County, the Texas Department of Transportation (TxDOT) and the cities of Frisco, Little Elm and Lake Dallas to build the 13.8-mile Lewisville Lake corridor project.
The NTTA’s 1.7-mile toll bridge is a key segment of the project. The NTTA is responsible for the design, construction and operation of the toll bridge.
The toll bridge will feature two lanes in each direction and an all-electronic toll collection (all-ETC) system on the project’s western approach. With all-ETC, drivers will not have to stop or look for change to pay the toll needed to drive over the bridge.
The bridge’s signature 360-foot-long red steel tied arch will begin to take shape over Lewisville Lake in December 2008. The LLTB design boasts a lighted, semicircular arch near the center of the bridge that will be tied together 58 feet above the bridge, spanning all four lanes. Also at its center, the 8-feet-thick bridge will sit 52 feet above the Lewisville Lake spillway elevation, meaning that the top of the arch will soar 118 feet above the lake surface.
The tall arch, coupled with lighted columns approaching both ends of the span will give motorists, area residents and boaters an easily recognizable landmark in southern Denton County.
Willow Grove Park, located in Lake Dallas, offers a great view of the toll bridge for those interested in seeing the installation of the arch or the bridge construction. Work on the arch is expected to continue through April 2009.
