Bernardston to VT line in Gill.
Extension of VT 142. In 1930, the VT side of the route was 101; that number was in use in Massachusetts along what would become US 44. By 1933, Vermont had renumbered to 30, which was also in use in Massachusetts. Between 1946 and 1950, VT renumbered again to 142. It may be that Massachusetts applied the 142 number to the road connecting to East Northfield across the river at that point; no map shows the number in MA until a 1975 state map which shows it on the current route down to Rt 10, staying to the west of the river.
