Starting tonight, Edens Expressway users will now get a taste of what the Dan Ryan commuters have been going through, as work begins this evening on a concrete patching project on the Edens from Lawrence Avenue to Lake-Cook Road. The project, which will cause a series of weekend and overnight closures on the Edens, runs through mid-November, so start getting used to having only one lane open on the Edens on the weekend. (As a reprieve for Northwestern football fans, the closures will not be in effect when NU plays some home games in the next couple of months.)
