According to Amasya municipality page, the bridge was constructed by Sadgeldi, the governor of Amasya between 1360 and 1382 who soon declared independence from the Eretnids.
[1] During the Ottoman Empire era the bridge was damaged in the 1824 flood and in 1825 earthquake.
It was repaired in 1828 by Hacı Yusuf, the ayan of Amasya (governor).
During the Turkish Republic, it underwent maintenance in 1940.
According to Fügen İlter, the bridge although constructed in 14th century, is quite different from the other bridges built in the post-Seljukid era.
