Bridge and Lock Tenders
Transportation and Material Moving
The work is running the machinery that opens and closes canal locks, dams, and railroad or highway drawbridges so vessels can pass. That means watching approaching boats for size and speed, listening for whistle signals, and directing them with signals, telecommunication equipment, or loudspeakers so lock and bridge space is used well. Levers also set traffic signals, navigation lights, and alarms for road and rail traffic. The same work covers logging vessel names and destinations, water levels, and weather, plus writing maintenance requests. It suits people who like close observation, timely decisions, and steady record-keeping from a fixed post.

AI & the future of this role
Remote sensors and automated controls may take over more routine bridge and lock sequences over time. On-site oversight for unusual traffic, emergencies, and safe passage still matters, though demand for constant human tending could ease.
