Earthwork Quantities at Bridge locations

Dear All, I want to calculate volume of earthwork for a corridor. I have created the design surface by using roadway designer with defined roadway templates. I got the total volume of earthwork for the complete corridor. Job is done.

But a major bridge is proposed at a particular location within the corridor. Here the total earthwork quantity is inclusive of major bridge. My problem is, the earthwork should not come in that particular bridge location. How can i overcome this problem.

Also I want to display the Bridge in Plan as well as in 3D. Can it be done with Bridge Tool? If so how can i do? Is there any learning video to do this.

Please help me in this regard.

Thanks & Regards,

Santosh
