Interstate 515 (I-515) was a 20.54-mile-long (33.06 km) spur route of I-15 in the US state of Nevada that ran 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. The freeway connected traffic headed from Boulder City and Henderson to Downtown Las Vegas via a direct, high-speed route, and it ran concurrently with, US 93, and US 95 along its entire length.

The I-515 designation was first approved in 1976, but construction did not begin until 1982, and was constructed in stages until it reached its former terminus north of Railroad Pass in 1994, when signs of the designation finally were put up. I-515 was built to bypass Fremont Street and Boulder Highway, both of which were former alignments of US 93, US 95, and US 466, and provide a direct freeway connection with Henderson.

In August 2017, the segment of I-515 between the I-215 interchange and the southern city limits of Henderson was redesignated as I-11. The Nevada Department of Transportation announced in 2022 that part of the preferred alternative for the future northward extension of I-11 would follow the remainder of the I-515 alignment. Signs for I-11 along I-515 and US 95 north of I-15 began to go up in 2024, and the I-515 designation was decommissioned in May 2024.^[4]^[5]
