Who is responsible for the silly signage posted on the entrances

North Wildwood - Who is responsible for the silly signage posted on the entrances to the highway into and out of North Wildwood that cautions drivers about the turtle crossings on that four lane highway. A turtle can't possibly cross that highway with the almost four feet high solid concrete barrier separating the eastbound and westbound lanes. Do the right thing, put up ground screening along the highway to prevent the terrapins from attempting to cross the busy highway where they are being slaughtered and causing potential accidents and deaths.
