Skewed culvert XS

[Uzy]

Hi,

I have to model skewed double barrel culvert and not sure how to place XS approaching and leaving culvert (XS 2 and 3). I am assuming they need to be parallel to the culvert inlet/outlet (perpendicular to river centerline) but not sure to cross the road with XS or not. Please see attached photo, white lines presents draft XS.

Any input from experienced RASsers would be appreciated.

Thank you,
Uzy

Any suggestion please. I am quite confused with this one skewed XS with culvert. I understand skewed bridges, our bounding cross sections should be parallel to the bridge and we can skew these cross sections and bridges. But with this one I am not sure, since section 2 and 3 has to be perpendicular to culvert in/out ; culvert is not skewed just road. Should I cross road with section 2 and 3 and just skew road?

Any help appreciated.
