What's really scary is some of the double level roads in cities. If there is a problem with the top, what's the alternate? Drive under the one that is falling apart? :realcrazy: There usually are plenty of other roads in that case, but they can't handle even close to the normal traffic volume. The real problem is our whole 'commuter' lifestyle that forces most people to drive distance for any meaningful employment. Don't see that changing any time soon...
