​The Miami Science Museum released renderings of its proposed $275 million new building this week, in addition to announcing a new timetable for the construction. Gillian Thomas, president and CEO of the museum, said the building, originally set to open in 2011, is now on course for completion in late 2013. With another six to nine months required to build out the interior, the earliest the museum could open would be 2014."The process has taken longer than we originally thought," Thomas says.
