Relayer2112 Posted March 16, 2018 Share Posted March 16, 2018 I'm no engineer, but can anyone out there explain how this sort of thing can happen in the modern age? All the engineering feats that have been accomplished in this country and a brand new pedestrian bridge collapses, killing six people. It appears that they were trying some new technique where they build the bridge next to the road and then rotate it when it was completed so that the road didn't need to be closed during construction. The bridge was built to withstand hurricane force winds and ends up not lasting more than five days. I just don't understand. Link to comment Share on other sites More sharing options...
Maverick Posted March 16, 2018 Share Posted March 16, 2018 I have no idea. All I know is that there is a very special young woman going to medical school down there (I'm in Virginia,) and I'm just glad that she is ok. My heart goes out to those who lost loved ones. 4 Link to comment Share on other sites More sharing options...

HemiBeers Posted March 16, 2018 Share Posted March 16, 2018 https://www.usatoday...ower/431418002/I'm no engineer, but that design seems way too indulgent for bridge that only carries pedestrians. 1 Link to comment Share on other sites More sharing options...
goose Posted March 16, 2018 Share Posted March 16, 2018 "The $14.2 million FIU bridge was designed under a process called “accelerated bridge construction” that allowed for larger sections to be built and then lifted into place." Seems like a bad idea. 2 Link to comment Share on other sites More sharing options...
Relayer2112 Posted March 16, 2018 Author Share Posted March 16, 2018 https://www.usatoday...ower/431418002/ Wow, it will be interesting to see who gets blamed for this one. Possibly miscommunication between the bridge designers and the group that moved the bridge into place (though you'd think that they would be one in the same).

Seems like a bad idea.It's not. It's actually fantastic applied correctly. We pioneered it here in Utah and have placed many new interstate overpasses and underpasses with it. Beats closing an interstate for weeks. You can do it overnight and not even interrupt one day's commute traffic flow. Link to comment Share on other sites More sharing options...
blueschica Posted March 17, 2018 Share Posted March 17, 2018 Our 6 pm news said that there are several newer bridges around central PA that are a similar design. All of them are now being inspected for safety. Glad to know that ! Link to comment Share on other sites More sharing options...

ABC is not known as risky, and this isn't going to change that for nonlaypeople. From the sounds of things, that engineer should've shut down traffic for that street once this was detected. But perhaps more information will surface. Link to comment Share on other sites More sharing options...

goose Posted March 17, 2018 Share Posted March 17, 2018 But seriously, from what I've read, it seems that this project was pushing the bounds of safe practice in taking a proven method to an extreme. Link to comment Share on other sites More sharing options...
That One Guy Posted March 17, 2018 Share Posted March 17, 2018 This reminds me why I didn't choose the structural engineering realm of civil engineering--because I have no interest in having liability over shit like bridge and building safety hanging over my head. No thanks! 2 Link to comment Share on other sites More sharing options...
