Separate plate girder bridges span between each pair of abutments in order to allow for expansion joints between the spans. Concrete is commonly used for low piers, while steel trestle work may be used for high bridges.

Slopes in the clear zone should be at most 1:4, and should typically be 1:6. Curbs: No curb is to be placed nearer to the roadway than the outside edge of the paved shoulder. Any curb is ...
