FRANKLIN N.H.- The Franklin City Council this week voted 7-1 to rehabilitate the historic Trestle bridge. Built in 1890, the Trestle Bridge carried railroad traffic connecting the Boston, Concord and Montreal Railroad to the Northern Railroad. It became defunct in the 1970s and was listed in the National Register of Historic Places in 1982. According to officials the cost to repair the bridge’s aged wood and instability is estimated at $1 million dollars.
