The eastbound lanes on the Rickenbacker Causeway Miami, the only route onto Key Biscayne, have been completely reopened after being closed since before dawn Friday morning.
Cops were dealing with an armed man who fired a shot, police said, but wasn't a danger to anyone but himself. During the incident, the eastbound lanes of the Rickenbacker and, early in the day, parts of Brickell Avenue were shut down. Various Key Biscayne businesses either never opened or worked with a short staff.
The police got the call about the man at 4 a.m. on Friday, according to Miami Police Spokeswoman Kenia Fallat.
