It is also concurrent with I-515 and US 93 between Henderson and Downtown Las Vegas. It crosses I-15 at the Spaghetti Bowl, where I-515 ends here and US 93 continues north on I-15. The highway continues as a freeway for several miles until again becoming a divided highway at Corn Creek Road northwest of the Las Vegas Valley. Shortly after entering Nye County, US 95 becomes an undivided two-lane highway past the Mercury interchange, as it meanders northwestward through the state, roughly paralleling the California state line. Along this route it runs through the Amargosa Valley serving Beatty before heading north into Goldfield and Tonopah. The highway is concurrent with US 6 for several miles north of Tonopah before it then heads north towards Hawthorne, Schurz (where it meets US 95 ALT which heads northwest towards Yerington, Carson City (via US 50 west), Reno (via Ramsey Weeks Cutoff, US 50 east, SR 439 north and I-80 west) and Fernley) and Fallon. North of Fallon it meets and runs concurrently with I-80 for 93 miles (150 km), from Exit 83 west of Lovelock to Exit 176 at Winnemucca. It then heads north to the border with Oregon at McDermitt, a distance of 73 miles (117 km). In Oregon, US 95 is an undivided two-lane highway in the sparsely populated high desert in the southeastern corner of the state, running completely in rural Malheur County. From the Nevada state line at McDermitt, the highway heads north and gradually climbs to its crest at Blue Mountain Pass, at an elevation of 5293 feet (1613 m) above sea level. US 95 descends to Basque Station (webcam) and Burns Junction at 3960 feet (1207 m), then eastward down to Rome (3390 ft, 1033 m) and up to Jordan Valley (4389', 1338 m) (webcam). The highway heads north-northeastward to the Idaho state line, entering southwest of Marsing in Owyhee County. The speed limit on US 95 in Oregon was 55 miles per hour until March 2016, when it was raised to 70 miles per hour in order to match the speed limits set by Nevada and Idaho. US 95 is designated the I.O.N. Highway No. 456 (see Oregon highways and routes), with the I.O.N. for Idaho–Oregon–Nevada.
