Low Impact: New Design for Short-Span Bridges

In Japan, due to its mountainous topography, engineers have always experienced problems in road building, which relies on constructing numerous tunnels and bridges. This article discusses how Japanese engineers have addressed this problem through the development of a new method for building composite truss bridges using suspension systems. The author notes that this construction method allows for the possibility of building a single-span composite truss that does not need either temporary supports or falsework. Moreover, use of this method has seen a reduction in construction costs and increased sustainability. It has also been reported that this method requires less excavation work, which has ultimately served to minimize the environmental impact. The author discusses the new method in detail and offers examples, including the Seiun Bridge in Yamashiro (a highway bridge spanning the Yoshino River) and the Ganmon Bridge (a pedestrian footbridge with a deck).
