Vermont Route 105 (VT 105) is a 98.135-mile-long (157.933 km) state highway located in northern Vermont in the United States. The route runs from U.S. Route 7 (US 7) in 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 US 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.
