The only cases where I would question the efficiency of use of resources are the first two, since the exact same signs could be just as easily supported by two single-support overhead sign structures, in both cases.  But as for the other examples, I wouldn't consider them wasteful at all, because the width among the signs is clearly enough to warrant a double-support overhead sign structure, and the only reason they span as much space as they do is that either there is insufficient space in the median to install a support structure, or there is no median at all.

I would think by the time 2 structures are built next to each other for a single sign, you're putting more effort into it than a single structure across the entire road.  Thus, I think the 1st 2 are fine as well.  The only thing that could be added is a pull-thru sign, but other than being a bit unusual due to the left exit, I think they are good.

That sign is now on a full sign bridge that carries a VMS.  The little sign almost gets lost next to the much larger VMS, which is further to the left than it otherwise would be in order to accommodate the little sign needing to be over the #3 lane.

As I recall, that particular sign (installed in the 2002-03 replacement on I-76) never had its lighting turned on.  Seems like a tiny little sign like that would be more important to make conspicuous.
