Good idea. The width of the bridge would have to be larger than the road so it sticks out a bit at well...

The bridges layer would have to come first in the mapfile, followed by the road line layer. Christy -- Christy Nieman GIS Technician DM Solutions Group, Inc.

You'll get the lines but you'll also get the line end caps. That's the real trick, turning those off. I'm not sure that you can.

I haven't worked with any shapefile extracts from OSM, so the data may already be like this. Assuming that you have a line shapefile that has a column called 'bridge', you could set up two classes in your roads layer. The first one would have an expression like ('[bridge] = 'yes') and the second class wouldn't have an expression so it would catch the rest of the lines. In the first class, you would stack two lines, the bottom one being the color of your bridge and wider than the roads line that will go on top of it.
