bridge and inline structure between same cross sections?

[crode]

Is it possible to model both a bridge and an inline structure (weir) inbetween the same cross sections? The model i am working on has a "perched" bridge with a lower approach highway which is overtopped during flooding events greater than the 25 year event. I am trying to determine the flow accross the roadway because this flow enters another tributary above a junction point instead of re-entering the same reach. Any thoughts or other a ideas on how to model this?

Try the multiple opening analysis. The hydraulic ref manual or ? gives guidence on a perched bridge scenario.
