The Euro Textures for the Avenue Viaducts actually put a physical median in there--these new crossings reference the same textures, so they'll get that, too. As far as other props go, there are T21s for the streetlights (which are messed up, as you can see) and the support pillars, so any additional prop work would need to co-exist/work around them.
Also, this (mostly) works now on the RUL end.
