在橋樑的的兩端將路徑切開，並在橋樑的地方加上 bridge=yes 和其圖層標籤。在一般的情況下，橋樑的起點會離道路的交叉口有一小段的距離，所以請盡量不要將橋樑直接連接到交叉口上；在某些特殊的情況時，道路的交叉口並不是設在地面上，而是整個交叉口都在橋樑上，你可以將實際上是橋樑的位置都標上橋樑的標籤。
橋樑前後端的斜坡處並不屬於橋樑的一部份，大部份的情況下不需要標上橋樑的標籤，重要的話可以加上代表土堤的 embankment=* 標籤，但土堤一般來說不需要設定它的圖層。
橋樑對車輛或行人的通行限制使用 access=* 標籤。
- 如果一個橋樑有使用 man_made=bridge 繪製橋樑輪廓，所有的標籤包括 name=* 和其他參數都應該被加在該圖徵上。橋樑的輪廓以及名字都會被彩現在 OpenStreetMap Carto 上。
- 如果一個橋樑是一個 highway=*，name=* 應該表示路標上寫的內容。一般會有兩種情況：
In case a bridge is represented by several ways or carries additional features there are currently two ways to indicate this:
- With man_made=bridge the outline of the bridge is drawn and the roads/ways passing the bridge are connected to the outline. All bridge-specific attributes like layer, name, reference, etc. can be tagged directly on the outline. In case of bridges with multiple levels the proposed relation bridge has to be used additionally.
- When using the proposed relation bridge all features of the bridge have to be members of the relation and all bridge-specific attributes can be tagged in the relation. In case the bridge has multiple levels only the relation can be used in order to group together all objects of the bridge.
Node-type objects which are part of the bridge-way are commonly considered to be on the bridge, these do not need an own layer tag.
Proposed features/Simplify man made=bridge mapping has some related ideas.
Bridges are landmarks and can pose significant obstacles/hazards for navigability.
|bridge||yes||Non-specific bridge tag, possibly combined with other bridge:* tags|
|bridge||aqueduct||A longer structure for carrying a canal or fresh water. Consider using historic=aqueduct for significant ancient aqueducts.|
|bridge||boardwalk||A plank walkway over wet or otherwise difficult terrain, usually low to the ground and supported by posts.|
|bridge||cantilever||A bridge where a span is supported at one end only. Usually, the free ends of two spans are fastened to one another, giving a longer clear span between supports.|
|bridge||covered||A covered bridge has a roof and fully or partly enclosed sides, usually to protect the bridge deck and members from deterioration. Consider also the combination bridge=*+covered=*.|
|bridge||low_water_crossing||Also known as an "Irish bridge", this is a low bridge which is engineered to carry vehicles above water at low flow levels and survive submersion at high flow levels. Consider also adding either ford=yes or flood_prone=yes on low-water-bridges that will sometimes be flooded on a seasonal and/or intermittent basis (see Discussion page).|
|bridge||movable||Movable bridges contain a span that can be moved up or to the side, often to provide greater clearance for traffic moving beneath the bridge. All such spans should be tagged with bridge=movable. Further information may be provided using bridge:movable=*. The fixed spans should be tagged separately, to make clear which part of the bridge is and is not movable.|
|bridge||trestle||A bridge composed of a series of short spans where each span is supported by a rigid frame, usually called a "bent" rather than a pier.|
|bridge||viaduct||A bridge composed of a series of spans, often short relative to its overall length. The spans may be arches, girders supported by piers, etc. For ways or features that raise a feature above the natural ground on mounds or earth walls, use embankment=*.|
This table is a wiki template with a default description in English. Editable here.
For bridges that are proposed, being constructed, being demolished, collapsed, the usual lifecycle tagging applies to the top-level tag carrying the bridge=yes specification, i.e. the highway=* or railway=* tag.
For construction, the scheme highway=construction + construction=(highway-type) is most common. For all other stages, the Lifecycle_prefixes are suitable. To preserve the OSM object history, do not delete an object that is collapsed if any remains are visible in the real world, and/or the object is being reconstructed.

- Relations/Proposed/Bridges_and_Tunnels. This enables the grouping of several ways using the same bridge. The relation also enables tagging a reference number for the bridge.
- Proposed_features/aqueduct - a proposal for historic aqueducts
- As can be seen in the image below, the primary road stops when it meets the river. So we are going to map the existing bridge over the river on the map below. We are going to attach the bridge segment to the existing road.
- Select the line tool from the top menu.
- Start mapping by using the line tool as follows:
- start on one shore, somewhere on the primary road, but don’t start the bridge mapping at the junction of the roads (the bridge should start/end before the junction)
- drag the line to the other shore, on the primary road, before the other junction of the road
- The bridge in this case is situated on a primary road, so from the “Feature Editor” menu we are going to select “Road Features”, then look for primary road and select it.
- Next we are going to add more attributes to this segment of the road that we are mapping as a bridge:
- Name: is the name of the bridge, in this case the bridge gets the same name as the road that is upon; in other cases the bridge can be “between” the roads (one road at one end of the bridge, another road at the other end of it) - in that situation the bridge can get either of those names, or it can have a specific name
- One way: if the bridge is used just for going one way or the other (this bridge has both ways, so we don’t check this)
- Speed limit: is there any speed limit on the bridge (in this case the road speed limit is in effect on the bridge too, and it’s 50km/h)
- Structure: mapping the structure as a “Bridge”; the layer tag is automatically added with the default value of 1 (typical value for bridges).
- Access: type of access for this bridge (on this particular bridge all type of access is permitted so we leave everything on yes as default)
- Lanes: number of lanes. This bridge has 1 each way, so we set lanes=2
- Surface: choose what type of surfaces is the bridge made of (in this case is asphalt)
- Road Number: the reference number or code of the road; in this case since we are keeping the information for the bridge consistent with the one from the road, we are filling there the national name of the road (DN71).
- All tags: here are presented all the attributes of the newly mapped bridge
- to add a custom tag, click on the plus sign (at the end of the list), type the name of the tag and insert a value.
