Interstate 515 overlays 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 accompany 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 refer to the Interstate 515 freeway as U.S. 95, and many business maps, such as those found in newspaper advertisements, erroneously show this road as Interstate 95. I-515 uses the mileposts for U.S. 95, so the exit numbers reference 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 completed by October 2018. I-11 was completed northwest from U.S. 95 to Foothills Drive in Henderson on January 27, 2018. Sign changes already 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. 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 may overlay the remainder of I-515 to Interstate 15 by Downtown Las Vegas. Alternatively the corridor may use the Bruce Woodbury Beltway (I-215) west or a new terrain alignment around Henderson and Nellis Air Force Base to I-15 northeast of Las Vegas.
Interstate 515 was first established by 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.

The turbine interchange joining Interstates 15 and 515 with U.S. 95 (Oran K. Gragson Freeway) northwest to Centennial includes ramps with adjacent Martin Luther King Boulevard. Project Neon through July 2019 reconstructs those connections in addition to the HOV flyover. Photo taken 07/22/17.
Exit 76B follows for the continuation of U.S. 93 north onto Interstate 15 through North Las Vegas. The two overlap to Garnett, where U.S. 93 turns north along Great Basin Highway as I-15 continues northeast to Mesquite and St. George, Utah. Photo taken 07/22/17.

Interstate 15 curves northward ahead of the off-ramp (Exit 41B) for SR 159 (Charleston Boulevard) west on the one mile approach to I-515 south, U.S. 93 south and U.S. 95 (Oran K. Gragson Freeway). Photo taken 07/15/17.
Exit 42A constitutes separate flyovers for both U.S. 95 (Oran K. Gragson Freeway) northwest toward Summerlin and Centennial and parallel Martin Luther King Boulevard just to the west. U.S. 95 extends the freeway north from I-515, 17 miles to SR 157 (Kyle Canyon Road). Photo taken 07/15/17.
Passing over Alta Drive and Bonneville Avenue, Interstate 15 north separates with Exit 42A for U.S. 95 north. The Project Neon project adds HOV ramps departing from the inside lanes at this location to a new flyover linking I-15 with U.S. 95. Photo taken 07/15/17.
Exit 42B carries two lanes of traffic from I-15 north to Interstate 515 & U.S. 93-95 southbound as they wrap around the north side of Downtown Las Vegas. Photo taken 07/15/17.
