MIAMI (CBSMiami) – I-95 road closures will be starting Monday night and continue over the next two weeks, allowing contractors to install five overhead sign structures for the $800 million dollar redesign and reconstruction of I-395 in Downtown Miami.

“This is a major closure because these structures span 89 to 119 feet and weigh from 23,000 to 33,000 pounds each, so we have to close the entire roadway,” explained I-395 Design Project spokesman Oscar Gonzalez. “We don’t want cars driving underneath as we install these giant structures.”
