LYNDON — The Sanborn Covered Bridge will belong to the town. The Select Board on Monday entered into a purchase-and-sale agreement with Arthur and Jeanne Elliott to buy the historic bridge and 1.5 acres of abutting land for $10,000. It was approved by a 3-0 vote. The acquisition brings all five of Lyndon’s covered bridges under town ownership and allows the town to proceed with plans to turn the bridges into tourist attractions and cultural hubs. The Sanborn Bridge will be key to those efforts. Located downtown and closed to traffic, it can be paired with parking, retail, tourism info, community events, and pedestrian amenities. Built around 1870, the Sanborn Bridge is the last of the Paddleford truss bridges that once crossed the Passumpsic River. The others were destroyed by the 1927 flood.
