Tube Truss Bridge Free 3D model

This 3D model was originally created with Sketchup 13 and then converted to all other 3D formats. Native format is .skp 3dsmax scene is 3ds Max 2016 version, rendered with Vray 3.00 A style of bridge I thought up while on an offshore oil platform in the Arabian Gulf. The arch trusses are similar to the trusses used on the platform walkways. I don't like the deck truss system I have, but I needed some kind of support system... I'm still thinking of a better way to hold up the deck, maybe a prettier concrete system.
