You have received replies already, but there are at least some pieces of non symmetrical infrastructure from that era that remain.
I live in Gothenburg, where trams are still one of the major forms of public transportation. There's at least one (presumably more) stop where the trams turn around that's quite inconvenient because it's built for left side driving:
If you want to board a tram that's turned there and will go back north, you can't do so at the platform where passengers usually wait. You have to cross the street, since the tracks actually don't connect to the main route until after the regular passenger platform.
All in all, things like that are quite rare. I guess a lot of our infrastructure - particularly highways, was built after the switch.
