Enhance any HO scale scene by combining roads and rails with the Cornerstone Urban Road and Rail Overpass kits. These highly - detailed HO structures, typical of designs from the 1900s onwards, were built as auto traffic increased, making them a great replacement for grade crossings. Many of these structures are still in use today. This overpass is a realistic addition to commercial, industrial, and suburban areas. It's also easy to pair with the Cornerstone Asphalt, Brick, and Concrete Street System kits (sold separately). Each model comes with detailed plastic parts molded in concrete and dark - gray colored plastic. The Urban Concrete Overpass Kit has several great features. It represents the more ornate concrete overpasses built for residential and suburban areas since WWI. It allows you to build a double - track railroad ballasted deck - bridge with a two - lane roadway below. There's a 14' (4.2m) clearance between the roadway and the bridge deck. The kit includes ornate concrete panels and walkway railings, along with arched column supports. The separate wing walls can be installed for straight or angled setups. Overall size with wing walls is 12 - 3/8 x 9 - 1/4 x 3 - 1/16' (31.4 x 23.4 x 7.7cm). The bridge and abutments only measure 8 - 1/2 x 5' (21.5 x 12.7cm), and the track height from the street is 2 - 5/8' (6.6cm).

Using this Walthers HO scale urban concrete overpass is a breeze. First, find a suitable spot in your HO scale scene, whether it's a commercial, industrial, or suburban area. If you have the Cornerstone Asphalt, Brick, and Concrete Street System kits, you can easily integrate them with this overpass. When assembling, start with the main bridge and abutments. Then, attach the ornate concrete panels and walkway railings. The arched column supports should be installed next. For the wing walls, you can choose to install them straight or at an angle according to your layout. As for maintenance, since it's made of plastic, you can gently clean it with a soft, dry cloth to keep it looking good. Avoid using harsh chemicals as they might damage the colored plastic. If you notice any loose parts, you can use a suitable plastic glue to re - attach them. That's all there is to it, and you'll have a great - looking overpass in your HO scale world.
