Torrence Avenue Bridge Demolition - Alternate View
Illinois Department of Transportation
Apparently an element of IDOT's decision to replace this bridge, instead if fix it, was that the waterway underneath it is no longer considered navigable. It is closed even to small pleasure boats. Therefore the greater clearance over the water provided by a truss bridge was no longer necessary. So down it came, with a big ka-boom. The replacement bridge will be much lower, not to mention boring.
A few interesting notes about this bridge. First, this bridge has been "doomed" for some time, the recent inspection merely accelerated pre-existing plans for destruction. Second, the approach spans for this bridge are not original and in fact these pre-stressed approach spans as I recall were one of the most deteriorated elements on the bridge. Thirdly, on this same road and exposed to similar traffic is the City of Chicago's lift bridge. The City instead however rehabbed their bridge, indicative that this type of work could have been done to this truss as well. Simple fact is that IDOT hates truss bridges, and even worse, they don't even consider this bridge to be historic.
This incredibly complex Pennsylvania truss bridge was closed for emergency repairs after an inspection in May 2015 found deterioration in a major structural member. When work commenced, it was decided it was beyond repair, so it was announced today that it will be demolished and replaced starting immediately. If you want to take a picture, hurry!
A practically identical Pennsylvania truss bridge over the Cal Sag at Archer Avenue is in much better condition, despite carrying heavier traffic including more trucks, and in fact was just repainted. See "Related bridges" above. One must wonder if this bridge at Torrence Ave had been maintained as well as its twin at Archer Ave has been, it would still be in good condition.
