How many manhole covers on UK roads?
There are at least as many covers as there are finished manholes. Most manholes are already covered, and there are covers in stock ready to replace them, and covers in the factory ready to ship out.

If you knew the proportion of unfinished manholes to stored and unused covers, you might be confident enough to boil it down to "There are at least as many covers as there are manholes."

Good question...have to use an estimate, because I am sure there isn't nationwide numbers on this. EPA estimates that there is 740,000 miles of public sewer lines in the US* and on average length between manholes on a city street is 300-400 feet. So multiply 740,000 x 5280 / 350 which equals.... 11,163,428 So roughly 11 million manholes in the united states.
