Any large, solid, immobile block that can be moved only with heavy machinery or great effort. Typically big solid things made of concrete for stopping larger vehicles. Sometimes natural boulders are used for the same purpose.

How to tag

Start by placing a tag


on a node that's part of an existing way to indicate where the barrier is. No need to tag each lump of concrete if they're closely spaced. It's a good idea to also state which kinds of traffic are allowed to pass, and which are not, for example:

Concrete blocks are not only used as barriers, they are also used for fixing guys of masts. These blocks are also marked as barrier=block.
