Interstate 515 Nevada
Interstate 515 overlaid the Las Vegas Expressway / Oran K. Gragson Freeway south from I-15 and Downtown Las Vegas to Henderson. U.S. 93 and U.S. 95 accompanied the commuter route from I-11 and I-215 (Bruce Woodbury Beltway) northward on the Henderson bypass to the Spaghetti Bowl interchange with Interstate 15. The Oran K. Gragson Freeway continues west toward Summerlin and north to Centennial in Las Vegas as U.S. 95.
Traffic reporters in Las Vegas generally referred to Interstate 515 as U.S. 95, and many business maps, such as those found in newspaper advertisements, erroneously showed this road as Interstate 95. I-515 used the mileposts for U.S. 95, so the exit numbers referenced the distance from the California border, south of Searchlight.
Formally established by Congress in 2012, the Interstate 11 corridor joining the Phoenix and Las Vegas areas overlays U.S. 93 northwest from the Mike O’Callaghan – Pat Tillman Memorial Bridge by Hoover Dam to the Boulder City Bypass, which fully opened by October 2018. I-11 was completed northwest from U.S. 95 to Foothills Drive in Henderson on January 27, 2018. Sign changes subsequently renumbered the southernmost extent of I-515 as I-11 following the opening of the new southbound lanes at Railroad Pass on August 15, 2017. The American Association of State Highway and Transportation Officials (AASHTO) approved the establishment of Interstate 11 from the Arizona state line to I-215 on May 29, 2014.
The continuation of Interstate 11 north from Henderson replaced the remainder of I-515 to I-15 by Downtown Las Vegas. Alternatively the corridor could have used the Bruce Woodbury Beltway (I-215) west or followed a new terrain alignment around Henderson and Nellis Air Force Base to I-15 northeast of Las Vegas. AASHTO approved the northward extension of I-11 to SR 157 (Kyle Canyon Road) in northwestern Las Vegas in October 2022. The remainder of Interstate 515 was decommissioned as a result.

Interstate 515 was first established by the American Association of State Highway Officials (AASHTO) on July 13, 1976 for a short stretch of the Las Vegas Expressway (U.S. 95) linking I-15 east with U.S. 93 (Las Vegas Boulevard) at Downtown. The route was however not signed, and remained on paper only as the Las Vegas Expressway was lengthened further south toward Henderson. Signs were observed for Interstate 515 and the Oran K. Gragson Expressway by site contributor Cary Todd in 1993. The Henderson bypass portion of I-515 was finished in 1995.

I-515 concluded just ahead of the Paradise Hills Drive underpass. U.S. 93/95 used to downgrade into an at-grade highway, but 2017 construction of I-11 upgraded the southbound roadway into limited access standards to Railroad Pass Hotel & Casino. I-11 opened from Railroad Pass east to a new parclo interchange with U.S. 95 south to Searchlight on August 15, 2017. 07/21/17
