There's news but I can't post link. They have opened the northbound underpass to I24 or will shortly The southbound overpass on I75 will have one lane opened tonight but...the Construction people will be working, starting tonight, on a temporr4y wall. Don't remeber exactly if they did some alteration work during the time from 64-65 when the completed that section of Interstate or not but don't think so.
Engineers last year, according to news gave the overpass a fair rating with concerns about tree near it growing roots into the bridge and wall gap.
I am not sure there was any rebar from roadbed or support into the wall.
