The Rix Modern Highway Overpass for N & HO scales is modeled after the
bridges built today to span over railroad tracks. This style of bridge is
typical of most new construction and is used all over the country. The Rix
Modern Highway Overpass consist of 50 foot spans which interlock together so
that any length bridge can be built. The piers are designed to be adjustable so
that raising or lowering the bridge for different heights is quick and easy.
