Cantilever and overhead sign bridges for signing and toll infrastructure

Hello everyone.

Not sure if this forum is the right place to formulate this question, but I did not find another one where it could fit better.

I need to perform the 3D model of the cantilever and overhead sign bridges for the signing and the toll infrastructure of a project. They consists of concrete or steel vertical towers supporting steel horizontal trusses, where the sign panels are placed.

May it be modeled using OBM?

Thank you very much.
