The route changes feature more 15-minute and 30-minute service as well as fast buses that bring commuters directly into Salt Lake City and the University of Utah.
The redesign will run night buses with the same route and route numbers as day service to eliminate the complexity of the former system.
UTA made 55 changes to the 80 routes, backed off some disputed fare increases and allocated an additional $1.5 million to enhance bus services in an effort to alleviate riders' anxiety and confusion.
The route redesign aims to increase efficiency while also attracting new riders by routing fast buses to suburban areas and realigning existing routes to feed TRAX and serve commuters, UTA officials said.
Maps are now available at UTA pass outlets and on buses. Printable versions are on the Web, http://www.rideuta.com. Riders also can call 888-RIDE-UTA (888-743-3882) for help.
