The Seto Bridge
The Tenryu Hamanako Railway Seto Bridge (天竜浜名湖鉄道瀬戸橋梁) is a reinforced concrete railway bridge of 1938 on the Tenryu Hamanako Railway about 1.5 kilometres east of Kanasashi Station in Hamana Ward, Hamamatsu City, Shizuoka Prefecture, and was registered as a Registered Tangible Cultural Property (structure) on January 26, 2011 (Agency for Cultural Affairs).
The Agency records a three-span reinforced concrete girder bridge 39 metres long with its abutments and piers; registration number 22-0154.
An Ambitious Ministry of Railways Design
The Seto Bridge is a 39-metre, three-span continuous reinforced concrete girder bridge with a long central span of 23 metres (Agency for Cultural Affairs).
Its unusual design fixes the girder to the pier on the Kanasashi side while resting it on movable bearings on the other pier (Agency for Cultural Affairs).
Why It Was Registered
It was registered under the criterion of contributing to the historic landscape of the country (Agency for Cultural Affairs). The Agency notes that it records an ambitious experiment carried out directly by the Ministry of Railways.
What to Look For
Look for the continuous concrete girder with its 23-metre central span and the bearings fixed on one pier and movable on the other (Agency for Cultural Affairs).
Visiting
The bridge is in Nakagawa, Hosoe-cho, about 1.5 kilometres east of Kanasashi Station (Agency for Cultural Affairs), and is in daily railway use. Tickets, fares and the turntable tour are covered on the Tenryu Hamanako Railway page. Do not enter the tracks or railway land.
