Looks like upwards of 100 Jersey Barriers there, not exactly giving me a warm fuzzy feeling about either the bridge or the temporary fix.
I'm aware of that suspension bridge in Indonesia that was asymmetrically loaded during some suspension hanger work and collapsed (several causes for that, BTW) but I'm not too familiar with cable stayed spans and their response to asymmetrical loading.
Presumably they know what they're doing, but the same could have been said about the Indonesian collapse too . . .
