Eldorado Parkway Alternatively known as the "main street" of Little Elm, this six-lane thoroughfare passes through the center of town and provides connections to Lake Dallas, Lakewood Village, Denton, Frisco, Plano, and McKinney. It also runs as different farm to market roads, and the LLTB. It starts off in Lake Dallas as the
Lewisville Lake Toll Bridge coming in from Swisher, and bears northeastward through Lewisville Lake. Upon reaching land, it curves north and continues upon that direction. After approaching a middle school, it starts curving again as it enters Oak Grove, as it becomes
FM 720. It continues as it curves and then heads southeast into the lake again in another chunk of land. It does a curve a bit more and goes northeast. Once it intersects with Hart Rd. Upon intersection, it heads east, and as it goes around
Villages of Woodlake (Little Elm community), it curves northeast. While headed northeast, FM 720 splits off and becomes Little Elm Parkway, and Eldorado continues said direction until intersecting with Walker Lane. Once it reaches that street, it continues east and past FM 423 it stays east heading into Frisco and the DNT.
Woodlake Parkway/Witt Rd This street is primarily a north–south thoroughfare which primarily runs through Little Elm, that also provides access to Frisco via the south side of Witt, and Panther Creek Pkwy which runs after the end of Woodlake. Along with Frisco, it also provides a way of transfer for those in Hackberry, along with McKinney if the City of Frisco expands it to SH 289. It begins at FM 423 as Woodlake Parkway, and the street before that is Panther Creek Pkwy in Frisco. It begins westward, but almost immediately starts curving through the Sunset Point neighborhood. Once finished, it intersects with Walker Ln and continues south. It continues as so for most of the route with some slight curves here and there. South of Eldorado is known as Witt Road. Once reaching Old Witt Rd, it exits Little Elm and enters Frisco.
Walker Lane This street is an east–west road that connects the High School to the rest of town and Eldorado Parkway. It is entirely within Little Elm. It begins at Eldorado Pkwy, and continues west towards Eldorado West. It slights north and continues west right after. After passing by LEHS, it stays west until approaching Hart Road, when it goes northwest as Stardust Trail.
