One eye-witness (a grenadier called Vigo-Roussillon) stated that the Austrians had men attempting to destroy the bridge, but that the French stopped their efforts by bringing up guns to fire along its length. It should have been fairly easy to prevent a French crossing because the bridge was wooden, and could have been burnt. It was about 200 yards long, and was a very simple structure consisting of piles driven into the river bed every few yards, with beams laid to form a roadway.
