==History==

Shadow Brook flows under the historic Hyde Hall Bridge, a covered bridge that was built in 1825. The bridge consists of a single {{Convert|53|ft|m|adj=on}} span using a Burr Arch Truss and was constructed by master carpenter Cyrenus Clark with assistance from carpenter Andrew Alden and stonemason Lorenzo Bates. Renovations to the bridge were performed by the State of New York in 1967.{{cite web|title=Hyde Hall|url=http://www.nycoveredbridges.org/hyde-hall/|work=New York Covered Bridge Society|accessdate=16 February 2014}}{{NRISref|2007a}} It is one of 29 historic covered bridges in New York State.
