Map making question-ravines

[dita]

Hi,

A quick question concerning bridges. Are you able to create a bridge that goes over something other than water? I`m playing around with the editor (by the way, the CD version editor makes all this experimenting alot quicker and easier-thanks!) and I can only seem to send them over water.

I`m trying to make a dry river bed, with a bridge over. I`ve tried creating the river, with water in it, then "removing" the water, needless to say, that doesnt work.

Any suggestions? Thanks
