Its big, unique, and it will be an impressive structure on your railroad. Wood bridges of this type arrived during the mid to early half of the 20th Century and survive in many rural areas today. This bridge is tall enough for a double stack container train and wide enough for double tracks to pass through. Every board, railing, support, and pier in this kit is made of laser cut basswood or micro plywood. Included are "photo" directions which make each step very easy to understand and construct without hours of reading and analyzing. Just follow the pictures to completion. Also included in the kit are signs for the road overpass and railroad warning signs for the bridge.
