Happy #LaborDay! Today, we’re celebrating the thousands of workers, past and present, who built our transit system and keep it running 24/7. These photographs from the #NYTMCollection show some of the very hard work that went into transit in #NYC over the years.

#LaborDay: This 1917 photograph from the #NYTMCollection shows a hyperbaric chamber or "hospital lock" used by tunnel laborers in emergencies. Compressed air kept the unfinished tunnels from caving in, but working in it was dangerous and could cause decompression sickness.

#LaborDay: The 1915 diagram from the #NYTMCollection shows the components of a "hospital lock" for tunnel laborers needing help with decompression sickness. Hospital locks were expensive and required specially-trained staff to operate, so only a few were located around the city.

#LaborDay: This #NYTMCollection tunnel laborer's badge from the 1910s was used to communicate exactly where a worker should be rushed in the dangerous event of decompression sickness. At this "hospital lock" he would receive recompression treatment to stabilize his condition.

In 1936, the Triborough Bridge opened, connecting Queens, Manhattan, and the Bronx. This #NYTMCollection photograph shows a 1932 sign announcing construction by Rogers and Hagerty. In 2008, the Triborough Bridge was renamed Robert F. Kennedy Bridge. What do you call the bridge?
