Transportation
Further information: List of state highways in Utah and Utah Transit AuthorityI-15 and I-80 are the main interstate highways in the state, where they intersect and briefly merge near downtown Salt Lake City. I-15 traverses the state north-to-south, entering from Arizona near St. George, paralleling the Wasatch Front, and crossing into Idaho near Portage. I-80 spans northern Utah east-to-west, entering from Nevada at Wendover, crossing the Wasatch Mountains east of Salt Lake City, and entering Wyoming near Evanston. I-84 West enters from Idaho near Snowville (from Boise) and merges with I-15 from Tremonton to Ogden, then heads southeast through the Wasatch Mountains before terminating at I-80 near Echo Junction.
I-70 splits from I-15 at Cove Fort in central Utah and heads east through mountains and rugged desert terrain, providing quick access to the many national parks and national monuments of southern Utah, and has been noted for its beauty. The 103 mile (163 km) stretch from Salina to Green River is the longest stretch of interstate in the country without services and, when completed in 1970, was the longest stretch of entirely new highway constructed in the U.S. since the Alaska Highway was completed in 1943.
TRAX, a light rail system in the Salt Lake Valley, consists of three lines. The Sandy line begins in the suburb of Sandy and ends in Downtown Salt Lake City. The Mid-Jordan line begins in the Daybreak Community, a southwestern valley suburb, and ends at the University of Utah. The West Valley Line begins in West Valley ending in Downtown Salt Lake City. The system is undergoing an expansion that will see the completion of 2 additional lines by 2014. The line to the Salt Lake International Airport is especially anticipated.
The Utah Transit Authority (UTA), which operates TRAX, also operates a bus system that stretches across the Wasatch Front and west into Tooele, and provides winter service to the ski resorts east of Salt Lake City. Several bus companies provide access to the ski resorts in winter, and local bus companies also serve Logan, St. George, and Cedar City. A commuter rail line known as FrontRunner operates between Salt Lake City and Pleasant View, and is undergoing an expansion south to Provo. Amtrak's California Zephyr, with one train in each direction daily, runs east-west through Utah with stops in Green River, Helper, Provo, and Salt Lake City.
Salt Lake City International Airport is the only international airport in the state and serves as a hub of Delta Air Lines. The airport has consistently ranked first in on-time departures and had the fewest cancellations among U.S. airports. The airport has non-stop service to over 100 destinations throughout the United States, Canada, and Mexico, as well as to Paris and Tokyo. Canyonlands Field (near Moab), Cedar City Regional Airport, Provo Municipal Airport, St. George Municipal Airport, and Vernal Regional Airport all provide limited commercial air service. An entirely new regional airport at St. George opened on January 12, 2011, replacing the old airport that existed on top of a plateau and had no room for expansion. SkyWest Airlines is also headquartered in St. George and maintains a hub at Salt Lake City. Frontier Airlines recently began daily non-stop service from the Provo Municipal Airport to the airline's hub in Denver. The service has so far been successful with more flights in the works.
