Hochbrücke Freimann, Highway bridge in Schwabing-Freimann, Germany

The Hochbrücke Freimann carries the A9 autobahn over the U6 metro tracks, a footpath, the Max-Valier-Straße and the Frankfurter Ring in Munich's Freimann district. The prestressed concrete hollow-box bridge stands on rows of four slender piers, replacing the earlier pairs of two, and bears two- to eight-metre acrylic-glass noise barriers on steel posts. The Frankfurter Ring junction lies on the bridge itself.

The bridge was built from 1958 to 1960 as part of Munich's planned outer ring road, which was only partly realised; the A99 now performs that role. Salt-laden water through defective drains corroded the concrete and prestressing steel, and after a trial repair of one span in 2002 proved uneconomical, a rebuild was decided in 2004. From 2007 to the end of 2010 the bridge was sawn lengthwise, the eastern half replaced while traffic used the western half, then the western half rebuilt.

The bridge's nickname Tatzelwurm comes from a legendary creature, a reference to its long, segmented shape. The name is used in Munich alongside the official name Hochbrücke Freimann. The areas around the bridge are currently unused open spaces, and a site for subculture is planned there.

The best time to view or photograph the bridge is early morning or late evening when traffic is lighter. The top of the structure is not open to the public, but it remains visible from various vantage points in the surrounding neighborhoods.

The new bridge, built from 2007 to the end of 2010, carries noise barriers two to eight metres high made of acrylic glass on steel posts, with steel-box absorbers on the inner side to prevent multiple reflections. It stands on four piers per row instead of two, and the thinner piers make it look less bulky than the old structure.
