| Tools for this tag |
Use bridge:support=* to indicate the position of the abutments and piers which support a bridge from beneath. The tag can also be used to map abutments and piers which remain after the span(s) of a bridge have been removed.
The simplest way to map these is to create a node along the way tagged with bridge=* centered on each pier. In cases where the pier has a significant footprint, this tag might be applied to an area enclosing that footprint, or to a way in the case of piers that are wide but thin (such as Error creating thumbnail: trestle bents).
Use this tag judiciously. The placement of piers may be useful in precisely indicating obstruction to ways and areas beneath the bridge, but when the piers are very closely spaced, mapping each one may make it difficult to work with the associated way. In such cases, simply tagging with bridge=trestle may be sufficient.
