The Port of Miami tunnel is now expected to open a day earlier than expected.
Port officials say fire marshal inspectors have given them the thumbs-up to open the tunnel Sunday at 10 A-M.
It was originally supposed to open Monday following a more than two month delay.
The $1-billion project has been plagued by problems like exhaust fans malfunctioning.
The delays costing the construction company some $9-million-dollars in late fines.
The tunnel should ease traffic by pulling thousands of cars a day off Miami's downtown streets and routing them onto the MacArthur Causeway.
