Here's one I found along US 49 near Seminary, MS
See anything odd?
Here's a close-up of across the road
Looks like someone got in too much of a hurry and got the One Way signs reversed! If you're not paying attention, you could be in a world of hurt. For the record, the second photo is correct.
I've dashed off a quick note to MDOT to see if they're aware of this. I wonder if they'll respond?
Follow up: they never responded. Not even a "thank you for your message"
