context_page_description: Interstate 580 is a 35.187-mile Interstate Highway in Western Nevada. It runs concurrently with U.S. Route 395 from an intersection with US 50 near the southern boundary of Carson City to the Reno Spaghetti Bowl interchange with I-80 in Reno. The freeway provides a high-speed direct route between Lake Tahoe and Carson City to Reno and I-80.
  Construction on a freeway between Carson City and Reno was planned since 1956, but construction did not occur until 1964. The freeway opened in sections, with the final section opening on August 2, 2017. The I-580 designation was approved on October 27, 1978, but the freeway was not signed as such until the portion between Reno and Carson City was completed following the opening of the Galena Creek Bridge in late August 2012.
context_section_description: I-580 runs from an intersection with US 50 in Carson City to an interchange with I-80 near downtown Reno. The only portion remaining to be constructed is the interchange at the freeway's southern terminus. Within Reno, the freeway is designated as the Martin Luther King, Jr., Freeway. Within Carson City, the freeway is designated the Carson City Deputy Sheriff Carl Howell Memorial Freeway, in honor of a sheriff's officer who was shot to death while attempting to rescue a victim of domestic violence from her house.
  The freeway begins at the junction of US 395 with the Lake Tahoe leg of US 50 and follows the eastern edge of Eagle Valley, where most of the population of Carson City resides. The highway loosely follows the former alignments of Edmonds Drive and Lompa Lane along the eastern half of the city, which were relocated or truncated to make room for the freeway.
  After rejoining the original alignment of US 395 at the Carson Tahoe Regional Medical Center, the highway crests Lakeview Hill to enter the Washoe Valley. The portion of I-580/US 395 and US 395 Alternate through Washoe Valley are prone to high crosswinds and, as such, the highways are frequently closed to high-profile vehicles. During prohibited times, trucks are rerouted to Eastlake Boulevard and US 395 Alternate (US 395 Alt.), which is the old route of US 395. The high wind area ends near the Bowers Mansion interchange near the northern end of the Washoe Valley.
  Unlike the old US 395 which ran along the valley floor of Pleasant Valley, I-580 is routed in the mountains overlooking the valley. While traversing Pleasant Valley, the highway crosses the Galena Creek Bridge, the largest cathedral arch bridge in the world. Upon the descent from these mountains the highway cuts through the center of one of the largest geothermal power plants in the United States, Ormat Industries' Nevada Power station, just before entering Reno.
  At the extreme southern edge of Reno, the highway has a junction with the Mount Rose Highway (SR 431) and Geiger Grade (SR 341), which connect the freeway with North Lake Tahoe and Virginia City, respectively. Upon entering Reno, the freeway proceeds in a generally northern direction, crossing Virginia Street, the old routing of US 395, several times. Along the way the freeway passes to the side of The Summit mall, Meadowood Mall and Reno–Tahoe International Airport. The elevated freeway also passes over a bus garage used by RTC Washoe, the local bus agency. The I-580 designation ends at the Reno Spaghetti Bowl where the highway crosses I-80; however, the freeway continues on only as US 395, heading towards the north valley neighborhoods of Sun Valley, Lemon Valley, Stead, Cold Springs Valley and Bordertown (which are all entirely part of the City of Reno) before eventually crossing the California state line.
