Re: [mapserver-users] Ideas about how to render over/under roadways/bridges in maps?
wow, really cool project and interesting configuration, thanks for sharing!

Check out our MAP files for the City of Amsterdam reference map at https://github.com/Amsterdam/mapserver/blob/develop/kbk50.map for the 1:50K map. The GROUP "lijnen" is the one you are looking for: it renders all casing from streets to regional thoroughfares, followed by the fills for the same lines. We then render all railroads and then the highways come last: again, we render the casings for all lines and then we finish with the fills in its own layer. This dataset doesn't contain an attribute for z-ordering unfortunately. For the 1:5K and larger, there is the https://github.com/Amsterdam/mapserver/blob/develop/bgt.map MAP file that does have an attribute for z-ordering that we use to create views per z-level, e.g. "bgt.wegdeel_vlak0" for z-level 0. Results can at https://data.amsterdam.nl/. Hope these MAP files give you some ideas how to go about rendering transportation networks.

Most of the battle is identifying the over/under in the data. Have you got that figured out? Id think it would be a matter of sorting: under, neither under or over and then over.
