After a visual inspection of the Brent Spence Bridge on Friday evening, the Kentucky Transportation Cabinet and the U.S. Coast Guard have closed the Ohio River to water traffic.
"Advanced steel testing is being conducted and once experts review the testing results we will update the public," Kentucky Transportation Cabinet Secretary Jim Gray said in a release Friday.
A crash on the Brent Spence Bridge Wednesday involving two semis, one carrying potassium hydroxide, caused a fire that burned for hours. The bridge has been closed until further notice, with officials estimating it could be weeks before traffic is allowed back on the bridge.
Engineering experts recently told WCPO such a chemical fire may not melt the bridge's steel tresses, but the 1500-degree flames could change the steel's atomic makeup.
