Old Blenheim Bridge was a woodencovered bridge that spannedSchoharie Creek inNorth Blenheim, New York, United States. With an open span of 210 feet (64 m), it had the second longest span of any surviving single-spancovered bridge in the world. The 1862Bridgeport Covered Bridge in Nevada County, California, currently undergoing repairs due to 1986 flooding (rebuild started in 2019) is longer overall at 233 feet (71 m) but is argued to have a 208 ft (63 m)clear span.[1] The bridge, opened in 1855, was also one of the oldest of its type in theUnited States. It was destroyed by flooding resulting fromTropical Storm Irene in 2011. Rebuilding of the bridge commenced in 2017 and was completed in 2018.
A group of local businessmen formed the Blenheim Bridge Company to construct the bridge. Nicholas Montgomery Powers[4][3] was brought in fromVermont to build it. The bridge opened in 1855, and remained in use for vehicles until 1932, when a steel truss bridge was constructed nearby. Since then, the bridge was pedestrian only.[1] It was declared aNational Historic Landmark in 1964 and designated as aNational Historic Civil Engineering Landmark by theAmerican Society of Civil Engineers in 1983.[6][7][8]
On August 28, 2011, record flooding along the Schoharie Creek, due toTropical Storm Irene, resulted in the bridge being washed away and completely destroyed.[9]
There is a great deal of conflicting information, and competing claims, about the Blenheim Bridge.
Many sources simply claimed the Old Blenheim Bridge as the longest surviving single-span covered bridge, which it was believed to be by total length of span. TheBridgeport Covered Bridge in California is longer in overall length. The New York Covered Bridge Society states that Blenheim bridge’s 219 feet (67 m)clear span was 2 feet (0.61 m) longer than "a bridge in California".
A report by theU.S. Department of the Interior states that the Bridgeport Covered Bridge (HAER No. CA-41) hasclear spans of 210 feet (64 m) on one side and 208 feet (63 m) on the other, while Blenheim Bridge (HAER No. NY-331) had a documentedclear span of 210 feet (64 m) in the middle (1936HABS drawings). In August 2003, measurements of post-repair Blenheim Bridge abutments were 209 feet 2 inches (63.75 m) on the upstream side, and 205 feet 6 inches (62.64 m) on the downstream side.[3]
Historically, the longest single-span covered bridge on record was Pennsylvania'sMcCall's Ferry Bridge with a claimedclear span of 360 feet (110 m) (built 1814–15, destroyed by ice jam 1817).[3]
The bridge was destroyed on August 28, 2011, as a result of flooding fromTropical Storm Irene.
A witness saw its roof deposited onto a modern bridge just downstream, when the bridge was swept away at about 1 p.m. Over subsequent months, the Schoharie County Highway Department collected pieces of the bridge up to about 30 miles (48 km) downstream.[10]
On July 21, 2015, National Historic Landmark designation for the bridge was withdrawn and the property was delisted from the National Register of Historic Places.[11]
A replacement for the bridge was built in 2017, exactly reproducing the design of the original. It was built to stand 15 feet (4.6 m) higher to avoid future floods.[12] Plans were for the bridge to "look and feel like it's the old bridge". Plans for replacement of the bridge took much time and effort; funding for reconstruction was at first opposed by FEMA, and the chair of a local committee characterized it as "a battle" to get approval.[13]
The construction cost $6.7 million, funded 75 percent by FEMA and 25 percent by New York State; it was started in early 2017. Preserved pieces of the original bridge were included as a memorial.[14] The construction contract was advertised with bids due in October 2016 by the New York State's Governor's Office on Storm Recovery.[15] On October 3, 2018,PBS broadcast an episode of theNova documentary TV series about the reconstruction.[16]
In 1837, the people of Pittsford, Vermont, contracted 19-year-old Nichols Powers to build a bridge over Otter Creek.
