Hello,
Thanks for your comment.
Address updated.
(I reused the old tag of the previous restaurant without checking address details...)
I've kept the tag tho because the restaurant doesn't have the same address as the rest of the building.

My bad. They're still 70 signs in the tunnel. I reverted the speed limit according to that.

Hello.

You're right, it must be a mistake.
I just modified a tag without checking the address. I suppressed the address tag as I don't know which is the correct number

Hello,
I went through the tunnel a few days ago and took a note saying the speed limit on my GPS / OSM was wrong there. Now you put me at a doubt. As I didn't recorded any images, I'm gonna check that carefully on my next trip there.
