Trivia tidbit: I-495 was numbered 95 when I-95 was being rebuilt in Wilmington; I-95 was called I-895 during that construction. Probably because Wilmington didn't want to give up its major Interstate, 95 came back when all was said and done, even though I-495 is by far the better through route.


It's not working here, but I-495 has these variable speed limits, I suppose for some form of inclement weather or collision. There shouldn't be much other reason to lower the speed limit - even during "rush hour", this through route remains pretty much unimpeded.


The front and back of the southbound slatted sign.


And the northbound one. These are up high on a viaduct over the Port of Wilmington, so between the height and proximity of the river, there must be plenty of shearing wind.


And now, a working one. As you can see, it's fueled by solar power during the day, and stores enough power to last the night. (I assume there's some manner of backup system for consecutive cloudy days.)
