There was a fatal bicycle accident last night on the Williamsburg Bridge bike and pedestrian path; an initial report tells us that the accident involved "a cyclist vs. a guardrail" and that the cyclist was DOA at the hospital. [Update below.]

Unlike last autumn's death of Sam Hindy, who accidentally pedaled onto the Manhattan Bridge roadway, this incident took place on the designated area for cyclists and pedestrians. But sections of the Williamsburg Bridge path are narrow and steep, particularly the ramp on the south side of the bridge, pictured here. And with last night's rain it's not hard to imagine an accident occurring on the slippery concrete.

UPDATE: The NYPD tells us that the cyclist, a 32-year-old white male, had a seizure while riding over the north side of the Williamsburg Bridge bike and pedestrian path. The unidentified man was pronounced dead at Beth Israel at 8:30 p.m. No criminality is suspected, but police are investigating and a full report from the medical examiner is forthcoming.
