Red images are backimage (the images to be displayed behind passing vehicles) and blue ones are frontimage (to be displayed before passing vehicles).

<WRAP info>If the bridge is one of a way which does not support hard slopes, remove "Ramp2" images to keep consistent.</WRAP>

The images "Image" are the central parts of the bridge which are displayed in the height beneath the bridge is not higher that one unit, otherwise "Image2" is displayed.

Bridges can have snowy images. To define them, a parameter must be added to the name of each image, equal to 0 for normal (summer) view and 1 for snowy (winter) view. Here is an example:

<WRAP box>FrontStart[E]=source.3.7 
 \\ 
 \\ #becomes ...
 \\ 
 \\ #normal view
 \\ FrontStart[E][0]=source.3.7 
 \\ #snowy view
 \\ FrontStart[E][1]=sourcewinter.3.7 </WRAP>
