A ford is a small part of a highway where a waterway runs over it.

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 in addition or instead of the highway.

Tags

Tag	Description
ford=yes	General purpose value
ford=stepping_stones	See Step-stone bridge on Wikipedia
ford=boat	A boat or ferry provided for fording

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.

Deprecated Tags

• highway=ford

If you know places with this tag, verify if it could be tagged with another tag.
Automated edits are strongly discouraged unless you really know what you are doing!

The way should carry the importance of the road (e.g. highway=tertiary), thus ford=yes is used to provide further details. When ford=yes is used on a node, don't use highway=*.

See Also

• Proposal (never voted on)
• flood_prone=* unlike fords are likely to be dangerous to cross if there is water across the roadway.
• intermittent=* used to indicate that a waterway (river, stream, etc.) does not have a permanent flow, so the ford may also be dry at times.
