the Legacy Highway project) which runs from Utah County along the west side of the valley until it reaches I-80. So far only the frontage road portion of the section that runs from Redwood Road (SR-68) at about 16000 South north to 5400 South (SR-73) at 6400 West has been completed. Construction on the section north to 4100 South has begun. However, these frontage roads function as a four-lane divided expressway until the freeway is completed. Another major roadway through the valley is State Street, which is the portion of US-89 that runs due south through the valley from Downtown Salt Lake City to Draper, before connecting with I-15. Public Transit There are several modes of public transportation, nearly all of which are operated by the Utah Transit Authority (UTA). Light Rail (TRAX) TRAX is a 50-station, light rail system (officially called, but rarely known as, "Transit Express") that serves Salt Lake County. In anticipation of the 2002 Winter Olympics, the system was approved in 1995. The first line began service on December 4, 1999 and currently links downtown with Draper, and another line to the University of Utah was completed in 2001, with an extension to the University of Utah Health Sciences Center in 2003. Extensions to West Valley City and to South Jordan were opened in 2011, an extension from downtown to the Salt Lake City International Airport opened in April 2013, and an extension from Sandy to Draper opened in August 2013. There are also eventual plans for a TRAX line to connect the Airport extension to the South Jordan extension, roughly along 5600 West (SR-172). In the far future, light rail might also be extended into southern Davis County and northern Utah County. Commuter Rail (the FrontRunner) The FrontRunner (so named because it runs along the Wasatch Front urban corridor), is a 16-station, commuter rail line that runs from Ogden to Provo through Salt Lake City. By 2040, it is expected to extend from Brigham City in Box Elder County to Santaquin in southern Utah County, the approximate extents of the Wasatch Front. Construction on the first segment, between Salt Lake City and Pleasant View (just north of Ogden) began on August 10, 2005 and was opened north to Ogden on April 26, 2008. The FrontRunner was extended to Pleasant View station on September 29, 2008, offering morning and evening service past Ogden. Although service north
