Upgrade your HO scale model streets and highways with the Cornerstone Modern Steel and Concrete Highway Overpass with Pipe Railings kit! This kit is jam - packed with realistic details and is a breeze to construct. The prototypes are commonly seen along slower - speed routes that offer pedestrian and bicycle access, as well as in scenic areas. Key features include: it represents pre - stressed concrete highway overpasses commonly found across North America; it suits highway scenes from the 1960s up to now; it comes with round and square support columns in short and tall styles to clear the railroad or highway below; you can build it as a single or double span and easily combine multiple kits (sold separately) for a larger setup; it's easy to install in new or existing layout scenes; it has detailed abutments with molded cut lines for easy customization; the parts are molded in concrete gray.

Using this HO scale highway overpass is easy. First, pick the right support columns (you have round and square, short and tall styles) based on whether you need to clear a railroad or a highway below. You can build it as a single - span or double - span structure. If you want a larger assembly, just combine multiple kits (each sold separately). When installing, it can fit nicely into new or existing layout scenes. For customization, use the molded cut lines on the detailed abutments. As for maintenance, since the parts are molded in concrete gray, keep them away from sharp objects to avoid scratches. If they get dirty, gently wipe them with a soft, dry cloth. Don't expose the overpass to extreme temperatures or high humidity, as this could damage the parts.
