Vermont Route 105 is a state highway located in northern Vermont, United States. The route runs from U.S. Route 7 in the city of St. Albans in the west to the New Hampshire state line in Bloomfield in the east. The road continues across the state line as Bridge Street, a short unnumbered New Hampshire state route to U.S. Route 3 in North Stratford, New Hampshire. As it is not a New Hampshire state highway, the connection is signed with Vermont state highway signage, similar to how connections to Vermont state routes are indicated elsewhere in New Hampshire.
