Here is a very nice 24" trestle with a walkway on the side. It is 9" wide by 7¼" high to the roadbed and has a 1¼" walkway. It is made from aged red cedar and glued together with waterproof Titebond III wood glue. It was built by a craftsman and is all handmade. It is for G-scale or 1:20.3 to 1:24 scale.
