Not according to the ChicagoLoopBridges site, courtesy of our city's resident bridge fanatics. Apparently this project is pretty far along.
The rehab is estimated to begin this fall; the city has an RFP out for the engineering.

Rehabilitate bridge trusses with selective replacements and/or repairs
Replace floorbeams and gusset connection plates
Replace bottom chord.
Replace bracing.
Replace roadway stringers to support new grating, evaluate the use of concrete-filled on the movable spans and elimination of jack beams
Current non-original railing to be replaced with a historic replica railing.
etc.

It would be great to eventually get a signature modern bridge downtown... but it will probably be the pedestrian bridge at McClurg. There are also new bridges planned for Taylor and Polk, which are also opportunities for high-end design. All of those bridges need to be moveable.
