<P> The design - build contract was awarded to a joint venture of Sundt and Stacy and Witbeck, for the 3.2 mile extension . Construction began in January 2013, with a celebration to mark the laying of the first track section being held in July 2014 . Construction work continued until December 2015, when it was announced the extension would open March 19, 2016 and that testing along the new stretch would continue . </P> <P> This extension is the first to extend light rail within the city of Phoenix . The system continues north from the previous terminus at 19th Avenue and Montebello, along the median of 19th Avenue, to a new terminus and park and ride located on the southwest corner of 19th Ave / Dunlap . The extension features two additional stations, located at Northern and Glendale avenues and is predicted to serve 5,000 riders per day during its first full year of operation . </P> <P> Currently the Valley Metro Rail system consists of one single line serving all 35 stations total, and denoted with a gold - yellow color on Valley Metro publications . The line starts in Phoenix at the 19th Ave / Dunlap station on its own right of way south of Dunlap before turning south on 19th Avenue for four miles . It then turns eastward on Camelback Road for 2 1 / 2 miles, then turns south onto Central Avenue where it continues all the way into Downtown Phoenix . At Roosevelt, the line splits into one - way segments: the Mesa bound portions line runs on First Avenue south before turning east on Jefferson Street; likewise, the Dunlap bound portion of the line starts at 26th Street on Washington Street before turning north on Central Avenue . (Interestingly, between 5th and 26th Streets on the Washington / Jefferson corridors, the Valley Metro Rail has a distinction of running in the middle of one - way thoroughfares .) After both tracks rejoin east of 24th Street on Washington Street, it continues past Sky Harbor Airport (which is connected by the PHX Sky Train to the light rail), then turns southeast ward crossing into Tempe . The line leaves Washington Street and crosses Tempe Town Lake on its own bridge, turns east along Mill Avenue before going into its own right of way near ASU . Going southward, it joins Apache Boulevard going east ward, with Apache changing to Main Street in Mesa where the light rail line ends at Mesa Drive . </P> <P> Service begins Monday through Friday at 4: 30 a.m., while Saturday and Sunday service begins at 4: 50 a.m. Service ends at approximately 1 a.m. Monday through Thursday nights, weekend service ends at 3: 25 a.m. Friday and Saturday mornings, with Sunday service ending at approximately 12: 30 a.m. Monday morning . </P>
