where does the light rail go in phoenix
Valley Metro Rail 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.[28] 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.
Traffic light On 9 December 1868,[7] the first non-electric gas-lit traffic lights were installed outside the Houses of Parliament in London to control the traffic in Bridge Street, Great George Street, and Parliament Street.[8] They were proposed by the railway engineer J. P. Knight of Nottingham who had adapted this idea from his design of railway signalling systems[9] and constructed by the railway signal engineers of Saxby & Farmer. The main reason for the traffic light was that there was an overflow of horse-drawn traffic over Westminster Bridge which forced thousands of pedestrians to walk next to the Houses of Parliament.[10] The design combined three semaphore arms with red and green gas lamps for night-time use, on a pillar, operated by a police constable. The gas lantern was manually turned by a traffic police officer with a lever at its base so that the appropriate light faced traffic.[11] The signal was 22 feet (6.7Â m) high. The light was called the semaphore and had arms that would extend horizontally that commanded drivers to "Stop" and then the arms would lower to a 45 degrees angle to tell drivers to proceed with "Caution". At night a red light would command "Stop" and a green light would mean use "Caution".[6]
