Any large, solid, immobile block that can be moved only with heavy machinery or great effort. They are typically placed by humans for stopping larger vehicles – but they can also be placed by natual processes. They are usually concrete structures, natural stone boulders or rocks, but also other objects like metal cubes are possible.

How to tag

Case where natural boulder qualifies for barrier=block

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 block of a group 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

access=permissive + motor_vehicle=no or

maxwidth:physical=1.9 (or maxwidth=1.9, if you don't want to distinguish between legal and physical restrictions).

The tag barrier=block is not only used for barriers, but also for fixing guys of masts, bridges, etc.
