Summerlin Parkway is a freeway in the western portion of the City of Las Vegas, Nevada, connecting U.S. Route 95 (US 95) to Clark County Route 215 (CC 215). Summerlin Parkway serves the master planned community of Summerlin.
Summerlin Parkway begins at its junction with the Las Vegas Beltway (CC 215). The road quickly becomes a divided highway with two lanes in each direction as it heads east from the intersection. At Anasazi Drive, Summerlin Parkway becomes a full freeway and maintains this status as it heads eastward through Summerlin and Las Vegas. The freeway terminates at the interchange with Rainbow Boulevard (SR 595) and US 95, locally known as the "Rainbow Curve" interchange.
Summerlin Parkway was initially constructed by the developers of Summerlin through the Summerlin Homeowners Association. The first construction along the parkway consisted of rebuilding the US 95 interchange and a divided highway west to Town Center Drive. Later projects funded by the Regional Transportation Commission of Southern Nevada brought freeway interchanges to Buffalo Drive in 1992 and Rampart Boulevard in 1994.
By 2000, Summerlin Parkway was built up to expressway standards to a western end at Anasazi Drive, and by 2004 the expressway terminated at the Las Vegas Beltway. A half-interchange was added at Durango Drive by 2005, and the Anasazi Drive intersection was converted to an interchange by 2006. Also in 2005, the Nevada Department of Transportation had reconstructed the US 95/Rainbow Boulevard interchange as part of its US 95 widening project (including a new direct connection from eastbound Summerlin Parkway to US 95 north which was not constructed in 1989).

The City of Las Vegas and the Regional Transportation Commission of Southern Nevada are currently proposing to improve Summerlin Parkway. Some of the proposed improvements include adding one additional lane, adding a new managed lane in each direction, adding auxiliary lanes, and aesthetics improvements along the entire parkway. No timetable for these improvements has been established.
An HOV flyover has been constructed in order to facilitate HOV movements between Summerlin Parkway and US 95 heading to and from downtown. The direct connection ramps opened in July 2012, even though Summerlin Parkway does not yet have HOV lanes.
