Mohawk Valley
Erie Canal Mapping Project
Rural Grove Area
Heading out from Sprakers up to Rural Grove along one of the loneliest roads in the Mohawk Valley, namely NY 162. Farm country, some amish but a lot of traditional dairy and abandoned farm land.
Lock 9 Bridge Dam
Lock 9 outside in Rotterdam Junction is not only a dam but also a bridge. Not all Bridge Dams though are actual bridges. See this article from the Canal Society, Bridge Dams on the NYS Barge Canal.
I wonder if the state will eventually replace the fairly unique bridge dams on the Mohawk River with traditional dams with tainter gates.

Tainter gates would be better if unpredictable heavy rains become more common during the navigation season and it’s necessary to adjust river levels on an emergency basis but bridge dams are better historically because they cause less problems with ice jams in the winter months as they typically have fewer piers. Tainter gates are generally more reliable. Bridge dams can’t be raised in an flooding emergency, causing flood waters to back up until the panels fail, although the design of bridge dams usually means during extreme flooding only the panels and maybe the panel frames are sacrificial.

Canal Locks and Structures
The locks, bridges, gates, and other structures used to operate the canal system today were built between 1905 and 1918. Many remarkable remains of stone locks, aqueducts and other structures built during the 1800s are also visible along the canals.
