Any of you engineer types ever heard of a newly


May 29, 2021, 9:43 PM

constructed bridge failing inspection and being torn down? One between Newberry and Winnsboro was almost finished when Covid hit and I didn't go back that way until last Fall, expecting the new bridge to be open but it looked just as it did in March. No workers were around for months and when they came back, they started tearing the deck off and this week some of the spans were removed. How expensive was that for the company involved? ( Not nearly as much as the halted nuclear plant in the same county that lost 10 billion).

Clover, I’m a ME grad born and raised in Newberry. What bridge are you referring to? Not the one over I-26 I hope!

It is on Highway 34 crossing Little River

in Fairfield County ( that is the fourth named Little River I know of in SC). Last March, it looked like all they needed to do to finish the project was to complete the concrete rails on one end of the bridge and pave the new lanes onto it. Whatever the problem was , I am glad they found it before tearing the old bridge down - would have been a major detour I imagine ( not real familiar with the side roads in that area).

Could be a couple of things, or more

We had a massive seismic retrofit program near me and after completion, a junior engineer found a design flaw that required everything to be redone, or, I think the seismic zones have just been updated. Charleston is a big one, diminishing as you radiate our from the city, but reaching all the way into the upstate. If the bridge was designed under the old criteria it would have to be redone, or, the contractor cut a few too many corners and got caught. Might be any of those.

you may be conflating the I-40 bridge in Arkansas

from 2021 with the Wando bridge from back in 2018 or so.

I saw that video in one of my first classes at Clemson. I think it was a Physics class. It is an amazing and eye opening video.

From a materials point of view that is amazing. You just

don't want to see concrete do that. In fact, under enough stress concrete will explode. Dr. Book in structures class taught us all about it. The replacement bridge has open trusses below it to eliminate the wind force that caused that.

I like this too. Steel vs heavy timber in a fire
