IN-192 (Cline Avenue) Booboos

Satellite
While studying a map looking for public access to take pictures of some bridges (below right), I noticed there was no bridge over the Indiana Harbor Canal for what seemed like a major highway.

Note that the road map view shows IN-192 as dotted-lines across the canal. I have discovered a video that confirms that a major highway was built in 1982 in East Chicago, IN, and then closed December 28, 2009. It was closed because "corrosion had severely weakened most elements of the bridge, including the bridge piers, concrete, beams and cables."

But building a bridge that did not last very long is not the major booboo documented by the video. The collapse of the bridge during construction, killing 12 workers, is the major booboo. The bridge was a relatively modern post-tensioned, cast-concrete design. The cause of the collapse was that the concrete pads used at the base of the temporary scaffolding evidently did not contain rebar. The pads cracked, the scaffolding buckled, the bridge went down. But not all of the spans collapsed at once. The collapse of the later spans endangered the rescue workers that were already on the scene.

The result of the investigation is that bridge designers are now supposed to be as careful with the design of the temporary supports needed when the concrete is poured as they are with the design of the bridge itself. I found it interesting that the reconstruction used pads made of huge timbers instead of concrete.

Since it was closed less than 7 years ago, I verified that the Bird's Eye View still shows it as intact. It was an impressive monument to stupidity/corruption/whatever. It was torn down in 2012, probably to reduce the visible embarrassment of failure and to get rid of an "attractive nuisance." Some parts used a wrecking ball while other parts used explosives.

I have noticed that Google now has a "3D" option which sometimes works. It allows me to get an "after" image.

On Bing's satellite view, if you turn off the label option, you can see the bridge is gone. But both Google and Bing road maps show the road to be intact. So if someone is planning a trip based on these maps, they could be in for a rude surprise.

Are they finally building a replacement bridge???

[The photo is of the toll gantry over the bridge's entrance.]
"The privately owned toll bridge spans 1.7 miles and rises 100 feet above the Indiana Harbor and Ship Canal. Its made up of 29 cast-in-place concrete columns that support 685 post-tensioned concrete single-cell box girder segments. The two-lane bridge is expected to carry 10,000 vehicles daily. The project took almost three years from the start of construction, and cost United Bridge Partners over $100 million to build. The company will charge drivers of two-axle vehicles with an E-ZPass or I-Pass transponder $2.50, but is waiving all tolls through Jan. 31, and in February, charging transponder users $1."
[So I need to do a field trip this Winter.]
