Reno sits in the Truckee Meadows on the eastern edge of the Sierra Nevada, and its freeways follow the river and the valley. I-80 runs east-west through the city just north of downtown, heading west over Donner Pass toward Sacramento and east through Sparks toward Salt Lake City. I-580, signed together with US 395, runs north-south through the city, heading south toward Carson City through Washoe Valley and north toward Susanville as US 395. McCarran Boulevard loops around the city, Virginia Street is the main north-south street through downtown and Midtown, and the Mount Rose Highway climbs southwest toward Lake Tahoe.
The Spaghetti Bowl interchange where I-80 and I-580 meet is the city's main bottleneck, and South Virginia, Kietzke Lane and McCarran back up at rush hour. Breakdowns pile up there and on the mountain routes. In winter, chain controls on I-80 over Donner Pass and on the Mount Rose Highway can bring traffic to a crawl, and cars that weren't ready for the mountains often end up stranded. The Mount Rose Highway climbs steeply above South Reno, and its summit is among the highest year-round crossings in the Sierra.
Reno-Tahoe International Airport sits southeast of downtown, close enough that its lots are a common place for a no-start after a trip. City buses connect downtown, the university and the main shopping areas, but most people drive. Weekend trips to Lake Tahoe and the ski areas add mountain miles even for in-town commuters.
Reno's neighborhoods climb the hills on all sides, from the Northwest and Somersett to Caughlin Ranch and the South Reno subdivisions, so many driveways sit on slopes with views across the valley. Those hillside streets hold snow and ice longer than the flats below.
