Not only have I updated more than *30* locations, I've added a number of new ones, including this one, looking east on Potomac at South Capitol (which will change pretty substantially once again when the new traffic oval arrives).

So go browse through the Slider Gallery to spend untold hours controlling the slide line yourself, going back and forth and back and forth and back and forth.... (and don't miss the "Browse Older Sliders" link to see the others that didn't get updated this time around.)

Working on these has really gotten me thinking about doing more with them, like allowing you to choose which photos of that view you want to slide between, etc. But these aren't auto-generated--every time I update them, I have to go find a new photo that at least sort of matches the original one, then crop it so they align as much as possible. So I might keep thinking on this for a while longer.

(In the meantime, try not to be mesmerized by the animated GIF. Watch the smokestacks at the far end of the street.)

PS: I've now created one additional slider, thanks to a reader request. If you scroll down a smidge on the Douglass Bridge project page, you can slide between a satellite view of the existing roadway and the overlay of the new oval.
