A construction worker at Pier D in the Long Beach Port was taken to a hospital Friday afternoon after a steel frame collapsed at the new Fire Station 20, authorities said.

The incident occurred around 2:12 p.m. when a part of the frame collapsed, trapping the construction worker, Long Beach Fire Department spokesperson Brian Fisk said. When fire personnel arrived, they used a ladder truck to perform an over-the-water rescue and successfully lowered the worker onto the ground.

LBFD personnel transported the worker to a local trauma hospital where his condition is currently not known, Fisk said.

The new Fire Station 20 is still under construction as part of a $109 million project aimed at tackling port-related emergencies. The two-story building includes a fireboat bay enclosure and floating dock. It is expected to be finished by this year.

The investigation into the incident, including what caused the collapse of the steel frame, is ongoing.
