The Lewisville Lake Corridor is approximately 13.8 miles and creates an east-west connection between Interstate High-way (I) – 35E and the Dallas North Toll-way (DNT). It includes improvements to the portions of roadway that follow existing western and eastern arterials near Lewisville Lake. The corridor is divided into eight sections, with Sections 4, 5, and, 6 designated under the current TxDOT FM 720 project.
FM 720 is a suburban road that begins at US 380 just west of the Lincoln Park town limits. It travels southward, through Oak Point, before turning to the southeast and entering Little Elm. It merges onto east-bound El Dorado Parkway, while the Parkway westbound connects with the Lewisville Lake Toll Bridge and the city of Lake Dallas. The route continues northeast and east, as the main thoroughfare through Little Elm. In eastern Little Elm, Eldorado Parkway branches off to the north, while Little Elm Parkway (FM 720) continues east to its terminus at FM 423. A map of project limits can be viewed on Page 8 and 9.
