Here are two medians at the gate as you exit Liberty in Historic Roswell. I've been completely puzzled (annoyed) at the presence of the median sign on the second of the two medians. I'm not sure why one of these has the median warning sign and the other doesn't. However, there's one thing I'm absolutely sure of and that is that the one there is WHOLLY UNNECESSARY. The only people that would ever hit that median are people turning around at the entrance gate and they wouldn't see it anyway.
These signs are suited for medians in environments where cars are going 45mph+ or where there is a visibility problem. NOT in a spot where the posted speed limit is 13 mph and certainly not where it is virtually impossible for a driver to hit the median. Stop putting up ridiculously unnecessary signs and pull the pointless ones down already!!!
