This bridge should be removed and replace by an easier to maintain monument. The cost for maintaining a bridge which is not being used are just to high. The railway running over it has moved into an underground tunnel 30 years ago.
But I do understand the why the bridge is a monument. I do not think the damaged in 1940 was because of the bombing, It was damaged in the battle that was fought over it. Many Marines most new recruits who had not finished there training yet, some just 16 years old , died defending it and stopped the German army from crossing the bridges over the Maas river. Not being able to cross the bridges was the reason why Rotterdam was bombed.
