The east bound bridge, which dates to the 1930's, is now scheduled for replacement in 2016. There seems to some sort of paranoia about the resemblance between this bridge and the I-35W bridge in Minnesota.
Now a paired bridge over the Wabash River, US 52 (Sagamore Parkway) crosses from the west bluffs to the built up roadway on the east flood plain.
