The feature that he is referencing is just a line segment with an additional
attribute of 'bridge=yes'.
* bridge: yes
* highway: trunk
* layer: 1
* name: Manchester Road
* ref: A56
If you just wanted to use the road data and not create an additional bridges
data set, you would likely need to split up the road features so that the
segment that is a bridge is an individual feature.
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.

Subject: [mapserver-users] Rendering bridges
Hallo list,
how can I render road bridges, like in mapnik?
(Example:
http://www.openstreetmap.org/?lat=53.398022&lon=-2.352222&zoom=18&layers=null)
Which symbol can I use?
Greets,
Tom
