Pierre Pflimlin bridge

From Wikipedia, the free encyclopedia

The bridge being built over the Rhine south of Strasbourg.

The Pierre Pflimlin bridge (Pont Pierre Pflimlin in French) is a 957 m long (main span 205 m) motorway bridge over the river Rhine between Germany and France, south of Strasbourg / Kehl. It is named after Pierre Pflimlin, a french politician, and was opened in 2002. The funding for its construction was provided to 55.5% by France, 38.6% by Germany and 5.9% by the European Union. ^[1]

[edit] Construction

Planned for several decades, it was built during the late 1990s / early 2000s by the construction companies Bilfinger Berger and Max Frueh. ^[2]

The central segments (located over the river) were built in balanced cantilever, cast-in-place fashion, extending outwards from each of the two pylon islands constructed in the stream. A concrete volume of 18.000 m3, 760 t of prestressing steel, and 2.700 t of reinforcing steel were used in total. ^[3]

The pylons were constructed on caissons floated into place and secured with 50 m deep foundation piles, and are designed to withstand earthquakes and ship impacts.

The approach bridge on the French side was built in segments, and then pushed horizontally onto the approach pylons, while the approach bridge section on the German side was built by another German company and was cast in place with standard formwork.

The hollow construction of all bridge segments has both pre-stressed and post-stressed components, realized by the French specialist construction company Freyssinet. The formwork was provided by Peri.

[edit] Function

The bridge carries two traffic lanes and two pedestrian / cycle routes. Its main function is to reduce pressure on the only other close-by Rhine bridge, the 'Pont Europeen'/ 'Europabruecke' at Strasbourg-Kehl to the north, by connecting the motorway Lauterbourg/Strasbourg-Saint-Louis/Basle from France to the A5 Hamburg/Frankfurt/Basle motorway in Germany.^[1]
