Historical Remarks:
The bridge name originates from the Slate family who lived on a farm along the river north of the bridge. It is the second bridge on this location, the first having been built around 1800. In 1842 William Wheelock was halfway across the earlier bridge with a span of four oxen when the bridge collapsed dropping both driver and animals into the river. Although no one was hurt, Wheelock engaged an attorney from Keene to seek damages from the town. The current bridge was damaged by a snow plow in 1987 and was repaired at a cost of $2,000. The Slate Bridge was listed on the National Register of Historic Places. On March 8, 1993, the Slate Bridge was destroyed by fire. At the time of publication, the town of Swanzey had expressed the intention to replace the structure with a new covered bridge.
