This bridge was modelled in real world scale (approximately 15 meters wide, 194 meters long and 57 meters high). The Alcántara Bridge in Spain was used as inspiration and reference. This bridge was built from 104-106 AD by the romans. There is also a high-poly version available.
All of the textures are included and named locically -same for the UV-Maps.
The scene in the preview image was just made to give an idea of how the bridge could be integrated into the landscape. So I did not put much effort into building and texturing it.
Do not hesitate to ask any questions.
