Austria. It's one of the most beautiful countries on the planet, yet someone in Austria's autobahn department seems determined to hide its lovely scenery from motorists. Where a year ago you could see a castle, now the view is of a wall. Such walls are common in Austria and most are without windows. While no one wants residents to suffer with roadway noise (assuming that's the reason for them), there are studies saying shrubs are effective for sound attenuation. Austria, tear down those walls!
