The Northern Arizona Intergovernmental Public Transportation Authority (NAIPTA), is making several service changes and updates to the Mountain Line Ride Guide to better serve transit riders. 

The changes, which will go into effect on Jan. 10, are designed to be a mid-year service update to the Mountain Line Ride Guide that was launched in August. NAIPTA typically debuts major service changes and new Ride Guides in August to coincide with the school year, and makes smaller updates in January to fine tune the schedule.
