Future

An additional extension—which included widening the existing roadway from four to six lanes from Shader Road to the U.S. 441/Orange Blossom Trail intersection, constructing two new overpasses and completing a new 1-mile alignment extension to Forest City Road/S.R. 434 at the intersection with Edgewater Drive/S.R. 424—was completed in 2013. Benefits of the extension include a direct connection between John Young Parkway and SR 434 and a much-improved alternate route to serve commuters during I-4 Ultimate construction. Future improvements include widening John Young Parkway from SR 50 to Shader Road from four lanes to six lanes. This capacity improvement project will also improve the level of service and enhance safety. Design is expected to be complete in Spring 2015. Construction is currently not funded; the duration is anticipated to be 24 to 30 months.Florida Department of Transportation
