The Cogan House Covered Bridge is 93 foot (28 m) long Burr arch truss covered bridge over Larrys Creek in Cogan House Township, Lycoming County in the U.S. state of Pennsylvania. The bridge was built in 1877, rehabilitated in 1998, and is on the National Register of Historic Places. The bridge is named for the township and village of Cogan House, but is also known by at least two other names.

Despite the 1998 rehabilitation, as of 2006 the bridge structure's sufficiency rating was only 17.5% and its condition was deemed "Basically intolerable requiring high priority of corrective action".

Name
The bridge's official name on the National Register of Historic Places (NRHP) is "Cogan House Covered Bridge". It is the only covered bridge ever built in Cogan House Township and the name comes both from the township and from the village of Cogan House, which is near the bridge. Cogan House Township and the village are named for David Cogan, who settled on Larrys Creek in 1825. Cogan was the one of the few settlers in the area for many years and grew tired of living nearly alone in the wilderness. In 1842 he abandoned his homestead, as did a neighbor named Carter. Their houses were used by hunters and travellers and the name Cogan's House was given to the area. Cogan House Township was formed from parts of Jackson and Mifflin Townships on December 6, 1843.

The covered bridge is at the base of Buckhorn Mountain, and the road to the former village of Buckhorn crossed the creek on it. The mountain and vanished village have given it the name "Buckhorn Covered Bridge", and this is the name used on the official plaque erected by the Lycoming County Commissioners to mark its rehabilitation and placement on the NRHP. This is despite the fact that "Buckhorn" is not the name used on the NRHP, and the Commissioners officially called it the "Cogan House Covered Bridge" as of 1966.

Finally, Landis (1966) refers to it as the "Larrys Creek Covered Bridge", since it crosses Larrys Creek, and says this is the name used by local historians. Larrys Creek is name for Larry Burt, who was the first settler at the mouth of the creek when the surveyors came through in 1769. Landis acknowledges the "Cogan House" name, and says the bridge has also been known by the names of "several tenants who lived in the little farm adjacent" to it. These other names have fallen out out of use, and are not given by Landis.

History
A petition from the citizens of Cogan House Township for a bridge to be built was filed on September 4, 1876.

A major flood on June 1, 1889 washed out every other bridge on Larrys Creek. The Cogan House Covered Bridge was one of the few bridges in Lycoming County to survive this flood (fallen trees upstream formed a dam which helped protect it). The same storm system caused the Johnstown Flood, which killed over 2200 people.

It is one of only three 19th century covered bridges remaining in Lycoming County today (the others are in Jackson Township over Blockhouse Creek and Moreland Township over Little Muncy Creek). The flood also destroyed the West Branch Division of the Pennsylvania Canal at the creek's mouth.
