Pfaffendorf Bridge

The Pfaffendorf Bridge (German: Pfaffendorfer Brücke) is the oldest bridge over the Rhine at Koblenz in the German state of Rhineland-Palatinate. It carries federal highway B 49 over the Rhine and connects central Koblenz with the suburbs of Pfaffendorf and Ehrenbreitstein. The first bridge was completed in 1864. The current bridge was built in 1953 after this bridge was destroyed in the Second World War.

A column on the Rhine shores (opposite the Weindorf Koblenz restaurant) commemorates the original construction of the Pfaffendorf Bridge between 1862 and 1864. According to the inscription on the front of the column, the foundation stone was laid in the reign of King William I on 11 November 1862 and inaugurated on 9 May 1864.

It was initially just a railway bridge over which the trains of the Rhenish Railway Company ran to Oberlahnstein, connecting the left and right bank lines. It had three spans constructed of wrought iron, each 97 m long, across the Rhine. The height of the arch was 3.14 m. It had two 10 metre-high towers at each end of the bridge, which had iron bars that could be used to seal off the bridge in the event of war. In addition, the right bank was protected by the Horchheim Gate Fortress (Horchheimer Torbefestigung) built between 1864 and 1867.

The bridge was built as the result of negotiations between Prussia and the Duchy of Nassau. Prussia wanted a line from the existing left bank line to connect with the eastern hinterland of the Rhine that would not be quickly interrupted by enemy advances in case of a war with France. Nassau, however, advocated a line along the right bank of the Rhine. On the other hand, Nassau was looking for an opportunity to link the left bank line to its own rail network. Under the agreement signed in 1857, Nassau granted a concession for the building of the Lahn Valley Railway via the Prussian cities of Gießen and Wetzlar through Nassau territory to Koblenz, on one hand, and the construction of the Pfaffendorf Bridge on the other hand.
