That overpass is relatively new (or at least recently refurbished) and is part of the new entry into the GE aviation plant on the right side of your screenshot. Notice that it leads into Aviation Way. So, as it is the entrance into the plant, it probably actually is a named overpass.
And yes, the plant and that overpass are in Evendale.
Thanks for posting this, I hadn't seen it yet. Your title says 'prior' to the incident. The linked statement seems to just say they helped them get away safely and organized (and used an elementary school to do so?!) but I don't think it indicates that they helped prepare for the event or anything like that. (Although, I wouldn't be surprised if they did, it just doesn't seem like this info backs that up)
