Based on standard-design long steel bridges used coast-to-coast since the early 1900s, this Pratt truss design offers maximum overhead and side clearance — perfect where double-stacks and other tall cars need to pass through. At 15\" assembled, this is the centerpiece span for serious viaducts and crossings.\u003c\/p\u003e\n  \u003cp\u003eLooking for more HO Scale bridges and building kits?
