Workers were forced to close the eastbound lanes of the PortMiami tunnel for about one hour Thursday morning after a cargo truck broke down on the exit ramp to the port and then a second truck smashed into the gate arm that came down when the facility shut down.
There were no injuries or serious damage at the $1 billion tunnel, said Christopher Hodgkins, Miami Access Tunnel chief executive officer.
It was the biggest incident at the tunnel since it opened Aug. 3, Hodgkins added.
The tunnel’s eastbound lanes were closed for about an hour while the broken down truck was removed.
Never miss a local story.
Workers were expected to close the tunnel’s eastbound lanes overnight to repair the damaged gate arms, Hodgkins said.
