The 2011 American State Litter Scorecard ranked Nevada (tied with Mississippi) as a bottom-three, "Worst" jurisdiction in the U.S., for overall effectiveness and quality of statewide public space cleanliness—from state and related litter/debris removal efforts.
Amtrak's California Zephyr train uses the Union Pacific's original transcontinental railroad line in daily service from Chicago to Emeryville, California, serving Elko, Winnemucca, Sparks, and Reno. Amtrak Thruway Motorcoaches also provide connecting service from Las Vegas to trains at Needles, California, Los Angeles, and Bakersfield, California; and from Stateline, Nevada, to Sacramento, California. Las Vegas has had no passenger train service since Amtrak's Desert Wind was discontinued in 1997, although there have been a number of proposals to re-introduce service to either Los Angeles or Southern California.
The Union Pacific Railroad has some railroads in the north and in the south. Greyhound Lines provides some bus service.
Interstate 15 passes through the southern tip of the state, serving Las Vegas and other communities. I-215 and spur route I-515 also serve the Las Vegas metropolitan area. Interstate 80 crosses through the northern part of Nevada, roughly following the path of the Humboldt River from Utah in the east and passing westward through Reno and into California. It has a spur route, I-580. Nevada also is served by several federal highways: US 6, US 50, US 93, US 95 and US 395. There are also 189 Nevada state highways. Nevada is one of a few states in the U.S. that does not have a continuous interstate highway linking its two major population centers. Even the non-interstate federal highways aren't contiguous between the Las Vegas and Reno areas.
The state is one of just a few in the country to allow semi-trailer trucks with three trailers—what might be called a "road train" in Australia. But American versions are usually smaller, in part because they must ascend and descend some fairly steep mountain passes.
RTC Transit is the public transit system in the Las Vegas metropolitan area. The agency is the largest transit agency in the state and operates a network of bus service across the Las Vegas Valley, including the use of The Deuce, double-decker buses, on the Las Vegas Strip and several outlying routes. RTC RIDE operates a system of local transit bus service throughout the Reno-Sparks metropolitan area. Other transit systems in the state include Carson City's JAC. Most other counties in the state do not have public transportation at all.
Additionally, a 4-mile (6.4 km) monorail system provides public transportation in the Las Vegas area. The Las Vegas Monorail line services several casino properties and the Las Vegas Convention Center on the east side of the Las Vegas Strip, running near Paradise Road, with a possible future extension to McCarran International Airport. Several hotels also run their own monorail lines between each other, which are typically several blocks in length.
McCarran International Airport in Las Vegas is the busiest airport serving Nevada. The Reno-Tahoe International Airport (formerly known as the Reno Cannon International Airport) is the other major airport in the state.
