Yeah, it looks like they forgot to take the sign-writing class. Everyone think they can write a sign until they try it. It’s a simple skill, but it’s not entirely without skill.
Anyway, the handwriting on the sign says “50% off select merchandise. Price will scan at register. Final sale.”
The picture of the “Chinese 50 lane road” was an internet hoax. It wasn’t a road. It is a toll gate, and it also only has 25 lanes.
The Katy freeway that OP posted has 26 lanes and is considered the “largest” road. The picture doesn’t really show it that well, and I’m also not sure if the feeder roads ought to count. It “only” has 6 ordinary lanes in both directions but a lot of entryways, exits and other designated lanes.
According to Guinness Book of Records, the widest road is in Brazil and is 250 meters wide. However this is also just a technicality, because it is also a 6 lane road with a really really wide median strip.
