Old Rhine Bridge

The Old Rhine Bridge at Konstanz spans the Seerhein. It is a combined road and railway bridge. In addition to one track of the High Rhine Railway at kilometer 413.5, it carries the Konzilstraße, the road that connects the borough of Petershausen with the city centre. The road bridge carries two lanes into the city center and three lanes in the other direction. Additionally, there is a bicycle lane in both directions on the left and a sidewalk on the right. In the 19th century, distance markers were placed along the Rhine; they start counting kilometers at this bridge.
