Plaka Bridge

Plaka Bridge is a 19th-century stone one-arch bridge in Greece that collapsed during the floods of 1 February 2015.

It is located at the borders of Arta and Ioannina prefectures, above the waters of Arachthos River. Administratively, it belongs to the community of Plaka-Raftaneon. With its arch of 40 metres width and 17.61 m height, it was the largest one-arch bridge in Greece and the Balkans, and the third largest one-arch stone bridge in Europe. It also had two small auxiliary arches of 6 metres width on its two sides.

It was considered "one of the most difficult, single-arch bridges to construct."The bridge was the starting point for rafting and canoeing on Arachthos River.
