Interstate 515 (I-515) is a spur of Interstate 15 in Nevada that runs from the junction of I-15, US 93 and US 95 (the Las Vegas Spaghetti Bowl Interchange) in Downtown approximately 20 miles (32 km) southeast to just north of Railroad Pass in southeastern Henderson.
I-515 exists concurrently with U.S. Routes 93 and 95 along its entire length.
The freeway, which began construction in 1982, is a continuation of the Oran K. Gragson Freeway (named for the former Las Vegas mayor who advocated for the construction of the then Las Vegas Expressway) which ran primarily along the former West Fremont Street alignment between Las Vegas Boulevard and Rainbow Boulevard. The spur was completed southeast to Charleston Boulevard (SR 159) in 1984, to Tropicana Avenue (SR 593) in 1986, to Russell Road in 1988 and to Lake Mead Parkway (SR 564), at the time known as Lake Mead Drive (SR 146 west and SR 147 east), in 1990. In 1994, the entire freeway was completed to Boulder Highway, just south of Wagon Wheel Drive.
