I found this damage interesting because
- There are high winds here (coastal area) but the frontal area of a sign seems pretty small
- I thought they would make signs out of more corrosion resistant materials
These are only a few of tens if not hundreds of downed signs in the area
I would imagine that at some point we went from highways agency signage that was made to a standard to outsourcing to the cheapest bidder. There is also a possibility that signs can't be too rigid so they don't cut vehicles in half?
Very good points!
