Bunzlau viaduct, Poland

This is 490 metres long (some sources say 450 metres), built 1844-1846 over the Bober River, about 75 km south of Hirschberg, see earlier post.

After Stalin's border changes of 1945, Bunzlau found itself in Poland, renamed Boleslawiec (roughly pronounced Bola-slav-ee-ets).
