Keniston Covered Bridge #15



Location: South of U.S. Route 4, one mile west of Andover Village on Lorden Road over the Blackwater River in Andover.
Style of Bridge: Town lattice truss
Year of Construction: 1882
Original Cost: $745.57
Structural Characteristics: The bridge is 64'6" long with a clear span of 54'2". It has an overall width of 18'9" with a roadway width of 15'10" and a maximum vertical clearance of 12'0". It is partially sheathed on the sides and has a deep overhang reminiscent of the rakish prow of a ship. The bridge is posted for six tons.

World Guide Number: 29-02-02
New Hampshire Number: 15

Historical Remarks:
The structure of the bridge was built by Albert R. Hamilton. The bridge's name, Keniston, came from a prominent family of that name who lived for many years in one of the old homesteads in town. The bridge has been damaged only once, in 1972, when ice tore off several planks. The bridge was rehabilitated by the town in 1981 at a cost of $80,000. During the rehabilitation process, the bridge was lifted by two cranes and moved to a temporary site only a few feet above the water level. The engineers had to work quickly to make sure the abutment repairs were completed and the bridge relocatd to its proper location before heavy rains and rising waters could carry it away. The Keniston Bridge is listed on the National Register of Historic Places.

And as Wingnut and I saw it on the Rail Trail last summer on our bike ride:

Cilleyville Bog Bridge

The Cilleyville Bog Bridge, built 1887. Andover, New Hampshire

Historical Remarks:
The structure was built by a local carpenter by the name of Print Atwood. He was assisted by Al Emerson and Charles Wilson. Local folklore suggests that during construction, Emerson and Wilson became upset and cut some of the timbers short, causing the bridge to tilt. On the other hand, engineers might suggest that the tilt is caused by the very nature of the Town lattice truss design. The bridge was the last covered, and probably the shortest built in Andover. It was bypassed in 1959 and restricted to foot traffic. Located in the Cilleyville section of Andover, it was originally known as Bog Bridge. A Cilleyville Bridge was nearby, spanning the Blackwater river. After it was torn down in 1908, the original Bog Bridge became known as the Cilleyville Bridge. The roof was reshingled in 1962 at a cost of $600. On March 9, 1982 the roof caved in from excessive snow load. The town repaired it in July 1982 for $3,400. The bridge was the model for the Shattuck murals of typical New Hampshire scenes which were once located in the State House in Concord. The Cilleyville Bridge is listed on the National Register of Historic Places.
