MIAMI BEACH (CBSMiami) – If your travels take you to Miami Beach late Monday into Tuesday, there is a traffic advisory you need to be aware of.

At 10 p.m., one eastbound lane on I-395/MacArthur Causeway Bridge from 200’ west of I-395 to Biscayne Boulevard off ramp will be closed followed with the full eastbound closure between 1 a.m. and 5 a.m

Drivers trying to get to Miami Beach during the closure will be detoured via I-395 eastbound to Biscayne Boulevard off ramp to I-195 eastbound (Julia Tuttle).  All westbound lanes will remain open at all times.

The lanes will reopen Tuesday at 5 a.m.

According to FDOT, the full lane closure is necessary for safety reasons while they put up a sign structure and panels for the Port of Miami Tunnel  project.

Scheduled to open to traffic on May 2014, the $1.2 billion project will provide a direct access between the Seaport, I-395 and I-95 by creating another access to PortMiami besides the Port Bridge, which is currently the only connection to the mainland.

Drivers may call 511 before they drive or log on to to get real- time traffic and lane closure information.
