Ramp closures begin Tuesday night as major work begins to build a new connector from the inbound Dan Ryan Expressway to the Eisenhower Expressway. The new connector will be under construction until summer 2016.
Starting Tuesday at 10 p.m., the ramp from Roosevelt Road to the Eisenhower (I-290) and Congress Parkway will be closed, as will the ramp from Taylor Street to the inbound Dan Ryan, IDOT said. Detours will be posted directing motorists in both locations.
Staging work will continue on the Dan Ryan (I-90/94) on Wednesday and Thursday night, and several other closures and changes will take affect by 5 a.m. Friday, IDOT said. Those include:
The ramp from the inbound Dan Ryan to inbound Congress Parkway will be closed and a detour will be posted.
The inbound and outbound ramps from the Stevenson Expressway (I-55) to the Dan Ryan will be reduced from two lanes to one.
The right lane of the inbound Dan Ryan from the Stevenson to Roosevelt Road will be closed.
The ramp from the inbound Dan Ryan to the outbound Eisenhower will remain open, but will be shifted to a temporary roadway. The four lanes from Roosevelt Street to Van Buren Street will be narrowed.
The new flyover bridge will replace the existing single-lane ramp for motorists heading from the inbound Dan Ryan to the outbound Eisenhower, IDOT said. The current connector begins south of Roosevelt Road and sweeps over Harrison Street and the spaghetti-bowl interchange before connecting to the outbound Eisenhower near Morgan Street.
Officials say the new connector will open in summer 2016, and will improve efficiency and traffic flow.
The project is part of a $475 million overhaul of the Jane Byrne Interchange that is scheduled for completion in 2018.
The project as a whole aims to reduce interchange congestion by half. About 400,000 cars travel through the interchange every day.
