Building the Brooklyn Bridge involved documented fatalities and injuries tied to hazards like caisson disease and falls. The most commonly cited estimate for on-site deaths during construction is 20 to 24 workers. This count typically includes documented cases of decompression sickness, known at the time as caisson disease or the bends, accidents involving equipment, and other construction risks. Notably, John A. Roebling died in 1869 after a ferry accident, and his son Washington Roebling was incapacitated for years by caisson disease but survived. The project did not involve widespread public fatalities; impacts were largely limited to the workforce and immediate stakeholders during the 1869–1883 construction period.
Project timeline and context
The Brooklyn Bridge was constructed between 1869 and 1883, following approvals in the late 1860s. It combined wire-cable suspension and structural steel to span the East River between Manhattan and Brooklyn. Engineering leadership passed to Washington Roebling after his father John Roebling’s early death. The timeline includes major masonry assembly, caisson work, and cable spinning. Understanding when specific events occurred helps clarify when and how dangers were encountered and how safety practices compared to contemporary large-scale engineering projects.
Documented causes of death
Key hazards included caisson disease, falling objects, equipment-related incidents, and collapse or misassembly events. Caisson disease resulted from workers breathing compressed air under high pressure in underwater caissons; symptoms ranged from joint pain to paralysis or death. Protective protocols were limited, and medical understanding was incomplete. Other documented causes included scaffold falls, derrick accidents, and masonry injuries. The project’s complexity and new material methods introduced risks that were not fully mitigated by 19th-century standards.
Caisson disease (the bends)
Workers in underwater caissons excavated riverbed foundations while pressurized, making them susceptible to caisson disease. Washington Roebling directed many caisson operations despite becoming debilitated by the condition. The delayed and imperfect understanding of safe decompression contributed to both acute and chronic harm. Although not all cases were fatal, severe instances led to death either during or after the exposure windows.
Falls and object strikes
High work above the river or on masonry and steel elements exposed crews to falls and being struck by loads. Safety nets, then an emerging technology, helped reduce fatalities but did not eliminate risk. Rigging failures and unguarded edges contributed to traumatic injuries. The combination of height, moving loads, and sometimes wet or unstable surfaces elevated the danger level for ironworkers and masons.
Notable individuals and data sources
Key records point to a small number of deaths with clear identification. Washington Roebling’s survival, though physically limiting, underscores that not all high-profile cases ended in fatality. The commonly cited range of 20–24 deaths rests on project reports, newspaper accounts from the era, and later historical compilations. Discrepancies can arise from whether subcontractor deaths or indirect causes are included, but the central estimate remains within that band.

Comparison with other projects
When judged against other late-19th-century infrastructure efforts, the documented 20–24 deaths reflect the era’s limited safety understanding rather than unusual mismanagement. Projects involving tunneling, bridge work, and excavation commonly accepted high worker casualties. Over time, record-keeping improved, allowing more precise accounting for fatalities. The Brooklyn Bridge’s death count is thus consistent with risks of its time and type of work, though every life represents a serious consequence of demanding engineering challenges.
Common misconceptions
Some narratives exaggerate the number of deaths or claim large public casualties during construction. Verified records show no evidence of significant unintentional public deaths tied to active building activities. Other stories suggest far higher unverified counts; these are not supported by contemporaneous logs, inspections, or scholarly compilations. Understanding what is documented helps separate myth from accountable history.
Legacy and lessons
The Brooklyn Bridge stands as both an engineering milestone and a case study in workplace risk evolution. Its construction spurred later attention to decompression protocols and worker protection. Modern large-scale projects apply far stricter safety regimes, informed partly by hard lessons from endeavors like this one. The verified death count informs ongoing discussions about balancing ambition, technical uncertainty, and labor safety.
