A zone entirely or mostly covering a bridge.
A bridge is a structure built to span physical obstacles without closing the way underneath such as a body of water, valley or road, for the purpose of providing passage over the obstacle.
The zone must be possible to take in a safe and secure way from the bridge, but may also be possible to take from under the bridge.

Only one zone per bridge can have this attribute.

There are 5492 zones of this type.
