Aso Choyo Bridge
Aso Choyo Bridge

(318) foot span / (97) meter span
The Aso Bridge was a 206 meter long truss-arch that used to cross over the Kurokawa River before a landslide destroyed it during the 2016 Kumamoto Earthquake. The large slide also destroyed a section of route 57 as well as the west side approach spans of the Aso Choyo Bridge and the east side of the historical Daiichi Shirakawa Railway Bridge.
In 2020 an entirely new Aso Bridge was completed 600 meters south of the old crossing with a main beam span of 165 meters on piers as tall as 97 meters. The new crossing is 525 meters long with a span configuration of 3x38 +80+165+100 meters.
Just to the south of these road bridges is the famous and historic Daiichi Shirakawa Railway arch bridge. Completed in 1928 on the Takamori Line of the Minami-Aso Railway, the 152 meter long steel truss arch was also damaged in the 2016 earthquake and is scheduled to reopen in 2022.
