# Key:ford

Description v · d · e ford A small part of a highway where a waterway runs over it. Group: highways Documented values: 3 depth=* surface=* Status: de facto More details at taginfo

A is a small part of a highway where a waterway runs over it. A ford can be both constructed (e.g., with concrete) or with the natural creek-bed. It can apply to vehicle roads, or to foot, bicycle or horse paths.

Distinct from a bridge which goes over the waterway, or a culvert where the waterway goes under the highway.

## How to map

• Use a single node ford where a highway crosses a waterway that is mapped as linear stream without riverbanks
• Use the way-method for larger streams with mapped riverbanks

### On a node

The stream and highways should share a node where they cross marked with ford=yes.

### On a way

The highway should share nodes with the riverbanks where it crosses them and also a node with the waterway=stream where they cross. Split the highway between the riverbanks and apply ford=yes to this segment (in addition to all other information pertaining to the highway).

If the approach (up and down to the riverbank) to the ford is much different from the ford itself, it might make sense to split the way and tag them appropriately. (incline=* might apply for example).

You should not tag ford=yes on the waterway node, when used on the highway way.

ford=boat A boat provided for crossing. See the more common tag route=ferry.

## Useful combinations

• surface=* Obvious values here would be concrete, paved, sand, gravel and mud etc.
• depth=* Normal depth you might encounter. Probably deeper during flood or when raining heavily. Perhaps even set to 0 for fords that are dry most of the year.
• layer=* Should be same as crossing road. That is not set in most cases. You are both on the highway and in the waterway, and not separated logically as a stream under a bridge would be.
• tidal=yes Whether the ford is within the tidal range. You can expect the water level of fords within the tidal range to move up and down with the tide.
