Engineering expert discusses next steps after fire closes bridge
UC College of Engineering and Applied Science professor discusses bridge repairs
WLWT-5 turned to an engineering professor at the University of Cincinnati to explain what inspectors would be looking for to assess fire damage on the Daniel Carter Beard Bridge.
The bridge was closed to traffic in both directions early Friday morning after a fire erupted under the span on the Cincinnati side at Sawyer Point's 1,000 Hands Playground.
Nobody was injured in the blaze, but the southbound span was substantially damaged, officials said. The northbound span reopened to traffic on Friday night.

UC College of Engineering and Applied Science Associate Professor Gian Andrea Rassati spoke to WLWT5's Ashley Kirklen and Sheree Paolello about what engineers look for to determine if the span's steel or concrete sustained structural damage.
Rassati teaches in UC's Department of Civil and Architectural Engineering and Construction Management. He said inspectors will examine the structural integrity of the steel members.
“They're looking at which members will need replacing. And based on the pictures I've seen, there are several that will need replacement,” Rassati said.
“And they're also looking at the concrete deck, the roadway and all the ancillary structures like the signs,” he said. “So there's a lot to do.”
A fire caused by a truck crash damaged and closed the Brent Spence Bridge in 2020. That span was closed to traffic for six weeks.
Rassati said the fire captured on video Friday morning looked much bigger than the fire that damaged and closed the Brent Spence Bridge.
“That's the million-dollar question: how hot did that fire burn?” he said.
“Depending on the temperature and time of exposure, some steel members might be OK. And others that look OK might need to be replaced because of the temperature they reached in the fire,” he said.
Rassati said bridge repairs can be done more quickly than most people realize.
“It's suprisingly fast. The fabricators, erectors and design engineers know what to do. A lot of them were trained by our program,” he said.
“It's shorter than you think, but it's still going to be a little painful. It's not going to be days. It will probably be weeks or months.”

A formerly rare strain of COVID, BA.3.2, now is showing up in Ohio and 24 other states. Experts say so far it hasn't caused illness any more severe than other strains, but it might be somewhat more resistant to vaccines, as 91.7 WVXU News recently reported. Scientists have nicknamed the variant "cicada" due to its former low profile and current resurgence.
