General Road and Highway Discussion

Interesting, I never did see that being constructed.  That's a bit surprising as it looked like a proper retaining wall, which I wouldn't think would require mechanically stabilized soil--I see these types of walls simply built to retain existing earthen berms--but I'm not a geotechnical engineer.

They probably want the extra stability because of all the sensitive rail infrastructure.

An asphalt path could probably make do with just a retaining wall, and ground that is prone to a little settling.  The station is going to want things to stay a little more precisely aligned.
