OScale Bridge and Elevaed Track for Train Set.....Everything I Did

My son has Autism and if you know anything about it you know the kids with Autism love trains so i began research and was finding out things were very very expensive. I ended up designing a large bridge and elevated trestles and using Menards O-gauge O-Scale track. I finally finished it and he loves it so i thought i would share it. this is how it looks https://youtu.be/Tmm2NZ7HWXI
