Accessibility Tools Public transportation in the Upper Valley area is becoming more accessible to persons with disabilities. Thanks to the Americans with Disabilities Act (ADA), improvements in accessibility make traveling on fixed route buses easier for all riders. Advance Transit also provides ACCESS AT, a service for individuals with disabilities who are unable, because of their disability, to use fixed route buses. Rides on all Advance Transit buses are FREE. You can ride any Advance Transit bus as far and as often as you wish without paying a fare.
