Philadelphia was just a single span long, albeit two bridges involved, for N/Sbound. I'm not personally familiar with either location, but between Google Maps and the article, this is looking like a full elevated viaduct, and more than a single deck span. On the face of it, looks like a MUCH more complex problem to replace than Philly's.
- ls612 3y agoWhen the 35W bridge over the Mississippi collapsed in 2007 it took a year and change to replace it and they paid a premium to make it happen that fast. I don't recall there being any state of emergency declared in the twin cities though.
- bluGill 3y agoThat was a.more complex river bridge though. And the old design was known to not be useful. Replacing with the same design will be cheaper and faster.
