Dearborn Street Bridges

ChicagoLoopBridges shared
The current Dearborn St bridge was built at the same time as the
"corncobs" (aka Marina City in 1962). This bridge replaced
a Scherzer rolling lift bridge that was built in 1907.

I didn't realize that they were still replacing the rolling bridges until the 1960s. I guess if the foundation was good enough, there was no need to replace it. After all, the Cermak Road Bridge was refurbished rather than replaced.

There is a plaque on the current bridge with this picture and the text "Chicago's first movable bridge was constructed at this site in 1834. The timber span provided only a sixty foot opening for the passage of vessels. So dangerous to ships was this narrow draw, that the bridge was ordered removed by the council in 1839. The present bridge is the fourth at this site.Chicago Loop Bridges features a picture of the plaque.

When I looked at the Satellite image, I noticed some barges parked along side. So I saved a bigger view to record this view of the building of the riverwalk.

Some one stole our bridge! Not really, construction of the new Dearborn St. Bridge went on at the same time as construction of Marina City, on right, 1961.
