Drivers eagerly awaiting the reopening of the reversible center lanes on the Kennedy Expressway will have to wait a little bit longer. Reopening the express lanes, and the conclusion of the second of three years of construction on the highway, has been pushed back to January. Though lane closures began weeks earlier than usual this spring and work was initially slated to wrap up in the fall, integrating the technical components of the access system to the reversible lanes proved to be more complicated and time consuming than expected and pushed back the reopening date, officials with the Illinois Department of Transportation said. “The remaining work, which includes the configuring and connecting of the individual components to the overall system, is currently being completed behind the scenes,” said Jonathan Schumacher, IDOT’s bureau chief of construction.
