My parents live in a community where one of the roads is named something like "High Street" (not actually that; it's a little road within their development). That sign gets stolen a few times a year by college students from the next town over because it includes the word "high". They have never had a road barrier stolen or meaningfully damaged, though -- they have maybe a dozen in various places. They budget about $50/year to replace the signs. Still much less, even over rather a long period, than the cost of rebuilding a bridge.
