Enhance your HO scale scene by combining roads and rails with the Cornerstone Urban Road & Rail Overpass kits. These HO structures, detailed to perfection, represent common designs from the 1900s. As auto - traffic grew, grade - crossing replacements became a smart choice, and many of these overpasses are still in use today. They're a realistic addition to commercial, industrial, and suburban areas and can be easily paired with Cornerstone Asphalt, Brick, and Concrete Street System kits (sold separately). The Urban Steel Overpass Kit features parts molded in concrete and dark gray plastic. It's typical of steel overpasses built in industrial and commercial areas since the 1920s. It builds a double - track railroad ballasted deck - bridge with a 2 - lane roadway below, offering a 14' (4.2m) clearance between the roadway and the bridge deck. The girders, beams, and columns are highly detailed with scale rivets in medium gray. The separate wing walls can be installed for straight or angled setups. Overall size with wing walls is 12 - 3/8 x 9 - 1/16 x 3 - 1/16' (31.4 x 23 x 7.7cm), bridge and abutments only measure 8 - 5/8 x 5' (21.9 x 12.7cm), and the track height from the street is 2 - 5/8' (6.6cm).

Using this Urban Steel Overpass Kit is easy. First, take out all the detailed plastic parts from the package. Start by assembling the bridge and abutments according to the basic structure. Then, add the double - track railroad ballasted deck - bridge on top and place the 2 - lane roadway below. You can adjust the separate wing walls to fit either a straight or angled installation in your HO scale scene. When handling the parts, be gentle as they are quite detailed and can be fragile. Avoid dropping or applying too much pressure. For maintenance, keep the overpass away from direct sunlight and high humidity to prevent the plastic from warping or discoloring. If it gets dirty, you can use a soft, dry cloth to gently wipe it clean.
