Will AI replace Bridge and Lock Tenders?
AI can do 13% of the work Bridge and Lock Tenders do at least twice as fast. Real use has not caught up: none of their tasks show up in real AI use yet, but AI could speed up 5 of them. Robots can technically handle 9 physical tasks. 4 still need a person.

People already use AI for these tasks in real work, based on Anthropic's analysis of how Claude is used.

AI could do this next5 · 13% of time
AI can speed these up by at least half, but real use has not caught up yet. These are next in line.
- Record names, types, and destinations of vessels passing through bridge openings or locks, and numbers of trains or vehicles crossing bridges.5% of time
- Inspect canal and bridge equipment, and areas, such as roadbeds, for damage or defects, reporting problems to supervisors as necessary.4% of time
- Log data, such as water levels and weather conditions.3% of time
- Write and submit maintenance work requisitions.1% of time
- Prepare accident reports.under 1% of time
Robots can technically do this9 · 62% of time
Physical tasks that today's robots can perform in at least some settings. Robots are cost competitive for very few tasks so far, so this change moves slower.
- Maintain and guard stations in bridges to check waterways for boat traffic.Robots: structured workplaces18% of time
- Control machinery to open and close canal locks and dams, railroad or highway drawbridges, or horizontally or vertically adjustable bridges.Robots: purpose built settings10% of time
- Perform maintenance duties, such as sweeping, painting, and yard work to keep facilities clean and in order.Robots: structured workplaces10% of time
- Clean and lubricate equipment, and make minor repairs and adjustments.Robots: purpose built settings6% of time
- Raise drawbridges and observe passage of water traffic or lower drawbridges and raise automobile gates.Robots: purpose built settings5% of time
- Turn valves to increase or decrease water levels in locks.Robots: structured workplaces4% of time
- Stop automobile and pedestrian traffic on bridges, and lower automobile gates prior to moving bridges.Robots: structured workplaces4% of time
- Move levers to activate traffic signals, navigation lights, and alarms.Robots: structured workplaces3% of time
- Attach ropes or cable lines to bitts on lock decks or wharfs to secure vessels.Robots: purpose built settings1% of time
Still needs a person4 · 26% of time
No real AI use, no proven AI speedup and no robot that can do it yet. This is the part of the job to build on.
- Direct movements of vessels in locks or bridge areas, using signals, telecommunication equipment, or loudspeakers.8% of time
- Observe approaching vessels to determine size and speed, and listen for whistle signals indicating desire to pass.8% of time
- Observe position and progress of vessels to ensure best use of lock spaces or bridge opening spaces.6% of time
- Check that bridges are clear of vehicles and pedestrians prior to opening.4% of time
Your week is not the average
Describe what you actually do and get a personal report: your own tasks, what AI can already do, what stays yours and a 90 day plan.
What this means
Little of this work suits AI. The bigger change here is robots: today's robots can technically do 65% of the working time, though they are rarely cheap enough to replace people yet.
What to do next
- Get ahead on the 5 tasks AI could do next. These move as tools improve, so learning them early pays off.
- Keep an eye on the 9 physical tasks robots can technically do. Cost keeps most robots out of work today, so this shift is slower.
- Build on the 4 tasks that stay human. This is where your judgment, skill and relationships matter most.
