Hi, if you are adding speed limits, just keep in mind that winter and summer speed limits may differ. I'd leave the winter one as the default one then add something like:

maxspeed:conditional=120 @ (Apr 1-Oct 31) or whatever the dates usually are.

It's probably especially hard to determine the values for roads with dynamic displays instead of signs.

This one probably also needs
maxspeed:variable=yes
