Concrete double tracked bridge spline with concrete piers. Based on a mesh from 'QR Bridge Concrete Track Wood' by Willem2. Willem2 retains all copyrights to his original mesh. My thanks to the original author for his great content item! I have also included all my Blender 2.80 project files for this content item in a sub-folder called 'blender_files'. Before trying to access them be sure to first read the 'instructions_read_first.txt' file in that folder.
