(passing from West Valley City into South Salt Lake), and then follows along the south side of the 21st South Freeway (SR-201). After passing the Jordan River Service Center (one of UTA's two TRAX maintenance facilities) on the south, the track use a series of viaducts to cross South 900 West, South 700 West, the north end of Union Pacific's Roper Rail Yard, the UTA FrontRunner tracks, and South 600 West before reaching the "Spaghetti Bowl" (the junction of I-15, I-80 and SR-201). From South 600 West the Green Line briefly follows the route of the old Denver and Rio Grande Western Railroad (D&RGW) Sugar House Branch, which goes under I-15/I-80 and then briefly runs along the south side of West Andy Avenue to South 300 West. After crossing South 300 West it continues east until about 220 West where it reaches the Union Pacific right-of-way and takes a sharp turn north as it merges with the Blue and Red lines), before entering Central Pointe, which is just south of West 2100 South (SR-201). Central Pointe to Courthouse Station Central Pointe is the only TRAX station served by the S Line. The S Line platform is situated just southeast of the TRAX platform. (The S Line provides streetcar service east to the Fairmont stop in the Sugar House neighborhood of Salt Lake City.) Upon crossing West 2100 South the three TRAX lines leave South Salt Lake and enter Salt Lake City and continue north as they cross West 1700 South and West 1300 South. Just north of West 1300 South is Ballpark, which provides service to Smith's Ballpark. (Immediately north of this station is a non-revenue track that extends northwest to South 400 West at West 900 South and then north to West 600 South.) After Ballpark the three lines continue north in the center median of South 200 West, crossing under the 900 South/I-15 on and off ramps, until they reach the next station, 900 South. This station, which is just north of West 900 South, is an infill station and the last stop before the TRAX lines reach Downtown Salt Lake City. The three lines continue north in the median of South 200 West, crossing West 800 South, until they reach West 700 South. At West 700 South they turn east and proceed down the middle of that street for two blocks, crossing South West Temple Street (SR-270).
