The Utah Transit Authority provides extensive public transport coverage in Salt Lake City by means of a light rail system called TRAX, and an excellent bus service. One-day passes are available for use on both TRAX and the city buses, and there is an extensive Free Fare Zone for both forms of transport downtown around Temple Square. A one-way fare is $2.50, and a day pass costs $6.25. During the winter a ski bus connects the city to nearby ski resorts. Metered taxis are freely available throughout the city and can be hailed on the street or ordered by telephone. Self-driving in Salt Lake City is fairly straightforward as the city is designed on a grid system with wide streets and a freeway system connecting the suburbs and surrounding areas.
