Most movable bridges in modern infrastructure are already remotely operated or automated. Canal and waterway lock systems are following the same path. The tenders who remain oversee safety-critical infrastructure where automation failure demands human backup, or work historic sites where manual operation is maintained by regulation. Here is what the research says about the bridge and lock tender profession in 2026, and what you can do about it.

Bridge tenders operate movable bridges — bascule, swing, lift, and drawbridges — to allow watercraft to pass through waterways. Lock tenders operate navigational locks on canals and rivers, managing water levels to move vessels between different elevations. Both roles involve monitoring traffic (vehicle and marine), operating heavy mechanical systems, and ensuring the safe transition of watercraft. Automation has been the defining trend for this occupation for decades. Modern movable bridge systems are designed with remote operation capability: the Florida Department of Transportation, the US Army Corps of Engineers, and many coastal state DOTs have implemented centralised control centres where a single operator monitors and controls multiple bridges remotely, replacing the on-site tender. Camera systems, sensor arrays, and automated traffic barrier systems allow remote operation. The Panama Canal Authority has steadily modernised lock operations. The Tennessee Valley Authority and Army Corps of Engineers have automated many river lock operations. What keeps humans in the loop: emergency situations where automated systems fail during active operation — a vessel stuck in a lock, a bridge that fails to re-seat after opening, a sensor malfunction during high traffic. Federal regulations (Coast Guard and Army Corps) require operator accountability for bridge and lock operations. Some historic bridges (swing bridges on the National Register, early bascule designs) are maintained with on-site operators by regulatory or preservation requirement. The marine pilot coordination function — communicating with approaching vessels, coordinating high-traffic periods — is a human task. BLS projects significant decline for this occupation through 2032. The automation of bridge control infrastructure is ongoing.

Centralised remote bridge control is already operational in multiple states and is expanding. Lock automation at Army Corps of Engineers facilities is ongoing. The occupation is contracting.
By 2028, the majority of US movable bridges on active waterways will be remotely operated from centralised facilities. On-site tenders will primarily remain at structures with mechanical limitations on remote operation or those serving unusually high commercial marine traffic.
By 2031, on-site bridge and lock tender positions will be concentrated at a small number of complex, high-traffic, or historically significant structures. The occupation is substantially smaller than today. Workers in this field should consider adjacent roles in marine traffic coordination, waterway infrastructure maintenance, or public works operations.
Yes, significantly and steadily. Centralised remote operation centres now control multiple bridges from a single location, eliminating on-site tender positions. Army Corps of Engineers lock automation is ongoing. This is not a future risk — it is the current trend that has been reducing the occupation for decades.
The US Coast Guard administers the Drawbridge Operation Regulations (33 CFR Part 117), which govern how movable bridges must respond to vessel traffic. Bridge operators must comply with these regulations, and failures can result in significant penalties. The US Army Corps of Engineers governs navigational lock operations on inland waterways. Operators must hold USCG-required qualifications for facilities on navigable waters.
Marine traffic coordination and port operations — the human judgment in vessel traffic management is more durable than the mechanical bridge operation itself. Infrastructure maintenance roles in state DOT bridge divisions. Waterway operations supervisor roles at Army Corps of Engineers facilities. Commercial maritime licensing (USCG Operator of Uninspected Vessels) opens charter, tour, and water taxi work. Public works operations roles in local government.
No. BLS projects decline through 2032. The automation of bridge control infrastructure is an ongoing capital investment programme by state DOTs and the Army Corps of Engineers. Positions that remain tend to be at complex structures or those with mechanical limitations on remote operation. New entry-level positions are not being created at historical rates.
