There were covered bridges in Keene, but details on them are difficult to find. It's known that early bridges spanned the Ashuelot River at West Street and Winchester Street, and the Branch River at Marlboro Street. Also, a covered bridge was framed in 1838 by William Willson, a well-known local mechanic, to span the Ashuelot River on West Street. This was built in about the same location where Dale's Fordway had crossed the river and replaced the bridge that the first settlers voted to build in 1757. A walk on the north side was added in September 1868 to accommodate pedestrians traveling to and from the Wheelock Park Fair Grounds. It was removed on July 11, 1900, and replaced with an iron span.
The Winchester Street covered bridge was built between 1837 and 1840, and was replaced in 1910 by a steel one. This 1880's circa photo of the Winchester St. bridge is on file at the Historical Society of Cheshire County on Main St.
The bridge at South Keene on Marlboro Street over the Branch River was built so low that men complained their loads of wood could not pass through it, and the floor was lowered by the men of the town. In 1863 this bridge was rebuilt higher and wider.
No covered bridges exist in Keene today.
