Apart from this, the bridge would need to have a bend in it, which adds to cost, and several streets (Railway Tce, Morphett Rd (northern part), Addison Rd) would lose their connection to Diagonal Road. The rail bridge makes far more sense to me, although I admit it's a pity the station has only recently been built.
There is no good reason to build it on the western side of Diagonal Road when there's so much free space on the eastern side!
But it's in a primarily residential area, and an overpass (rail or road) would be rather noisy. The station was designed to be compatible with an underpass, and that's what they should build.
Looks like the station wasn't built for either a rail underpass or overpass.
Rail overpass would probably be cheaper and a better option.
