The Jomo Electric Railway Kasukawa Bridge was registered as a structure that contributes to the historic landscape of the country. The Agency for Cultural Affairs values it as a modern bridge that supported local transport.
What to Look For
The Kasukawa Bridge carries a single track on a four-span deck girder of 30-foot steel plate girders (Agency for Cultural Affairs). According to the Jomo Electric Railway, it is 42.1 metres long and 2.1 metres wide, with 95 sleepers.
The piers and abutments were rebuilt in reinforced concrete after Typhoon Kathleen in 1947 (Agency for Cultural Affairs).
