station it crosses under I-215 and then continues down the median of Old Highway 186 as that road splits from West North Temple Street and heads southwest towards I-80. Just after crossing South 2400 West, the Green Line crosses to the north side of the road as Old Highway 186 continues southwest to I-80. The tracks continue on the north side of the I-80 right-of-way, crossing over the Surplus Canal, until Old Highway 186 curves north again just east of the I-80/Bangerter Highway (SR-154) interchange and then merges with Terminal Drive as that road heads northeast and then north to the Salt Lake City International Airport. The tracks parallel the east side of Terminal Drive until it reaches the Airport Station, which is located immediately south of Terminal One. There is direct access to the terminal from the north end of the platform. Park and Ride Many TRAX stations include free Park and Ride lots, with some lots having as few as six parking spaces and others having nearly 1200. However, there are certain restrictions for all lots (for example, no 24-hour parking). Free Fare Zone UTA currently has a Free Fare Zone in Downtown Salt Lake City for transportation patrons that both enter and exit bus or TRAX service within the Zone. The Zone covers an area of approximately thirty-six city blocks and the boundaries are roughly North Temple, 200 East, 500 South, and 400 West. TRAX stations within the Zone include Arena, City Center, Courthouse, Gallivan Plaza (mistakenly identified as "Gallivan Center Station" on the Free Fare Zone map), Planetarium, and Temple Square. In addition, the Free Fare Zone also includes the area of the State Capitol (north to 500 North), the bus stops on 400 South between 200 East and 300 East, and three additional TRAX stations: Library, Old GreekTown, and Salt Lake Central. In June 2012 UTA revealed plans to eliminate the Free Fare Zone, but by September 2012 it announced that it would continue the Zone, but with some minor adjustments, including when and how fares are collected. Airport extension Construction began on October 22, 2008 on an extension to the Salt Lake City International Airport. The extension included six new TRAX stations. In addition to the Airport Station, five new stations were constructed along West North Temple Street (West 100 North), including one on top of the newly built North Temple Viaduct bridge. The
