使用 bridge:structure=* 描述各个桥梁跨度的承重结构。（跨度是桥梁在两个支承之间的一段。）简单的桥梁可能在两端所搁置的桥台之间只有一个跨度；其他桥梁可能有多个跨度和许多支承。有时一座桥梁在其长度上会有不止一种跨度类型。在这些情况下，可以在跨度类型发生变化的支承处拆分路径，并为每一段标注不同的 bridge:structure=* 取值。

|---|---|---|---|
arch
|
In an arch bridge, the span is supported by a curved arch, which transfers some of its weight into horizontal thrust against the abutments. | 
|
|
beam
|
In a beam bridge, the load is transferred entirely to a span resting on a support at either end, without additional reinforcement. | 
|
|
truss
|
In a truss bridge, the span consists of a series of interlocking triangular units which bear the load. | 
|
|
floating
|
A bridge whose load is supported by floating on water, rather than resting on fixed supports. Typically a pontoon bridge. | 
|
|
suspension
|
A bridge where the load is supported from a cable under tension, attached to anchorages at each end of the bridge. In most, but not all, suspension bridges, the cables are suspended between towers near each end of the bridge. | 
|
|
cable-stayed
|
A bridge where the load is supported by cables radiating from the tops of towers resting on supports along the line of the bridge. | 
|
|
simple-suspension
|
A simple hanging bridge construction, also referred to as swinging or hanging rope bridges. Bridges requiring special skills may be additionally tagged with sac_scale=*, those requiring special equipment with highway=via_ferrata
|
|
|
humpback
|
An arch bridge with significant vertical elevation changes of the bridge deck along the arch, also called moon bridges in Asia. | 
|
|
clapper
|
Stone bridge made from horizontal slabs resting on vertical slabs or piers. |

多结构桥梁
对于单一类型的桥梁，例如拱桥，在整座桥的轮廓（man_made=bridge）上添加 bridge:structure=* 可能很有用。尤其是当单座桥梁有大量标注了 bridge=yes 的路径时——多条人行道、车行道，可能因不同属性变化而被拆分。对于多种类型的桥梁，标注情况尚不明确，需要进一步细化[1]
