Louisville’s Speed Art Museumwill be closed for about three years while the facility undergoes a $50 million renovation. The work will begin in October of 2012. Director Charles Venable says the decision to shut down the museum for that long was a difficult one but made in the interest of public safety."We’re going to be a pretty complicated place to even be able to get the public into. Our front door is going to be torn down, things like that. It will be very hard to actually welcome people in the building and have them be safe," Venable told WFPL.Venable says the Speed will continue its outreach and other community programs during the shutdown.The renovation project will double the museum’s overall square footage and create new galleries, an education center and sculpture plaza.
