The Spanish Civil War broke out in 1936, and the Bridge witnessed the cruel events which affected the surrounding residents. It was hit during various bombing raids although without suffering fatal damage.
In the end, in June 1937, faced with the imminent arrival of the national troops, the Northern Army’s Engineers Battalion received orders to destroy all of the means for crossing the Nervión so as to hinder the advance of Franco’s troops. In the early morning of 17th June a massive explosion fatally wounded the Vizcaya Hanging Bridge and its crossbeam fell into the water. Paradoxically, on the 22nd June, five days later, the war ended on the Bilbao Front.
