Notes:

• Facility served by the bridge closed in 1925 at which time the bridge was likely abandoned. Towers appear to still be standing (in late 2010s).

• A Delaware County Primer complied by Sue Hudson. "West of Cooks Falls and east of Horton, on the O&W. Acid plant built here by Eugene King burned in June 1888, was rebuilt, and was later bought by local entrepreneur, George I. Treyz. Railroad suspension bridge constructed in 1911 by John A. Roebling's Sons Company of Trenton, NJ to connect Treyz's acid factory, saw mill, and planing mill on Russell Brook to the O&W, which ran on the other side of the Beaver Kill."
• Cooks Falls - Colchester Historical Society. "Arthur Leighton and George I. Treyz developed the acid factory industries in Cook's Falls... Treyz had a close relationship with the O&W Railroad, which helped both to prosper. Treyz installed a Roebling suspension bridge between his plant and the O&W Railroad. This siding was known as the Grove Switch. A narrow gauge railway was constructed and ran up Russell Brook to the Russell School. This line carried logs and sawed lumber down to the Treyz plant and the O&W Railroad."
