The Eau Rouge ( French for "red water") is a small river in Belgium that flows into the Amel (French Amblève ). The water is named after the iron-rich, reddish water in the upper reaches.
The river also played a role as a border in the past. At the time of the Romans, the Eau Rouge was the border of the administrative units of Tongeren (Civitas Tungrorum) and Cologne (Civitas Agrippinensium). Between 1815 and 1920 the brook marked the border between Belgium and Prussia .
The curve Eau Rouge the circuit of Spa-Francorchamps is named after the river.
Eau Rouge Valley Bridge
The Eau Rouge bridge ( Viaduc de l'Eau Rouge ) leads the A27 (E42) motorway , which runs from Battice to the German border near Steinebrück, in a wide arc over the Eau Rouge valley. Both the width of the valley and the extreme acidity of the soil near the stream are the reasons for the size of the bridge. It is 652 meters long, with the distance between the two central pillars 270 meters. The top of the bridge is 45 meters.
