Local bus routes are provided between the Dartmouth-Hitchcock Medical Center, Dartmouth College, the city of Lebanon, New Hampshire, and the towns of Hanover, New Hampshire, and Hartford, Vermont, including the unincorporated village of White River Junction.

Advance Transit was created in 1981 following the failure of the for-profit Tri-Town Bus Company.

In 1977 the Upper Valley Lake Sunapee Council (now the Upper Valley Lake Sunapee Regional Planning Commission) completed a Transit Development Plan for a non-profit public transportation system covering a larger service area.

The Plan was endorsed by the State of New Hampshire, and Advance Transit was then formed as a program of the Upper Valley Senior Citizens Council.
