Hello everyone! Brendan Keefe here.
It was pretty scary -- just don't look down!
239 feet above the Little Miami River to be exact. Wow, what a feeling!
Good question. Structurally deficient refers to the overall condition and safety of the bridge. Some engineers say such a bridge has already technically failed, because it can no longer carry the load it was designed to handle. Functionally obsolete refers more to the capacity fo the bridge (number of vehicles), meaning its lanes are too few or too narrow.
Do you mean on the catwalk?
Sure. It's fairly dangerous, but we were wearing safety gear. I did bump my head a lot, but the hard hat helped.
I don't wear earrings so the subject never came up.. now about bridge safety....
Another good question -- Ohio has 27,403 bridges under ODOT control. 23% are "deficient" That's about average.
Ohio inspects EVERY BRIDGE EVERY YEAR, while federal guidelines require inspections only every other year.
30% of Kentucky bridges are deficient. A little bit higher.
We were surprised to find so many bridges being replaced across the Tri-State -- it looks like the tragedies of the past combined with the recession to provide both the demand and the funding for new bridges.
Jon, it certainly makes me more aware. There was no clue driving over the Morrow bridge/I-71 that it was in such poor condition underneath.
Some inspections are done with a pair of binoculars, but fracture critical and structurally deficient bridges get an up-close inspection annually.
The video is from a GoPro camera mounted on my hard hat. It does amplify the sense of vertigo. There were good handrails and a steel-mesh "floor" so I felt fairly safe. I'm not afraid of heights, but I have a respect for them!
The 9 On Your Side archives are extensive. All the video came from our tape room. The film of the 1967 Silver Bridge collapse was transferred to digital video by Al White, one of the original employees of WCPO
ironmaiden, you must be proud of your father's work. The bridge has stood for 50 years!
We've got another five minutes on the chat....
We've got raw film of the Silver Bridge on the web story. Amazing.
The new Morrow bridge is a very interesting design -- something you see more down south. Officially it is "concrete box girder cast in place cantilever with steel post-tensioning"
We've got a pretty interesting story next Monday on protecting yourself against credit card theft/fraud
They usually do recycle the steel. The Morrow will be taken down piece by piece over the river, the rest can be imploded
If you've got more questions, I'll stay on a bit longer. Fire away....
ironmaiden, that's a good point. The contractor on the new Morrow is a company called Kokosing. Their trailer is down the acc
ess road from the northbound rest area just south of the bridge.
Any other questions before I sign off?
