It was a busy weekend for McHugh Construction and the giant red Stevenson crane (we call it “Steve” around here) at the Jane Byrne Flyover. One more section of girders was added west of the Halsted Street bridge, leaving a void only the width of Halsted Street to be spanned. If you’ve got a jumping bus like Sandra Bullock drove in Speed, go ahead and see if you can shoot the gap. Otherwise, you’ll have to wait for one more weekend of work. But don’t forget, there’s no ramp to the ground on the west end of the Flyover yet, either, so check your brakes.
