Toll Bridge Project 90% Complete

The Lewisville Lake Toll Bridge (LLTB) project is moving closer to completion now that the final large pieces of the arch have been installed.  Staff and contractors are now working to complete the next steps in the LLTB project, such as placing the steel runners that provide the base support for the decking, finishing the deck placement, installing the steel pieces that will connect the two arches, and stringing the cables between the arches and the base.

The 360-foot long steel tied arch is located near the center of the bridge, where the 8-foot thick bridge sits 52 feet above the Lewisville Lake spillway elevation. The lighted, semicircular arch is tied together 58 feet above bridge traffic, spanning all four lanes of the bridge. The top of the arch soars more than 100 feet above the lake surface. The arch is comprised of weathering steel that has a galvanized surface to prevent corrosion, adding to the bridge’s durability.

Installation of the arch began in late December 2008 when the first corner piece was set in place. All four corner pieces were in place by late January 2009 and the arch ribs began to take shape in March 2009. The bridge is expected to open to traffic in August 2009.

The NTTA is responsible for the design, construction and operation of the toll bridge. Upon completion, the LLTB corridor will open a new east-west connection between Interstate Highway 35E and the Dallas North Tollway, transforming Denton County’s infrastructure and providing more mobility options for area residents.
