Kasern valley crossing

The Kasern valley crossing is a 143 m long and 17 m high bridge on the Austrian A1 western motorway in the area of ​​the city of Salzburg . The original building from around 1940 was rebuilt in 2011/2012. The bridge is part of the Salzburg-Nord motorway exit .

Location and construction

The bridge is located 3.6 km north-northeast of Salzburg's old town and immediately west of the Kasern motorway service station at motorway kilometer 289.0. It lies in the border area of ​​the Salzburg districts of Kasern in the north and Itzling in the south. The Kasern valley crossing belongs to the eastern part of the Salzburg-Nord motorway exit. It connects the lower slope of a Plainberg foothills on the west side with the first hill of the Nussdorf hill in the east and therefore does not represent a really distinctive valley crossing due to the terrain .

The bridge construction consists of four individual structures, two for the main lanes of the motorway and two for the exit routes, with a total of nine lanes. It crosses several traffic routes:

Around 85,000 to 90,000 vehicles use the Kasern valley crossing every day (as of 2011/12).

history

This section of the Westautobahn including the bridge was built from 1938 as part of the former Reichsautobahn , which was supposed to continue from Munich to Vienna. Inmates of a nearby labor camp of the National Socialist Reich Labor Service in Bergheim were used to build the road . The work came to a standstill due to the war conditions in 1941. The bridge, which remained unfinished in the superstructure, was only completed around 1950. The two supporting structures for the lanes of the exit were created more recently and in the course of the redesign of the Salzburg-Nord motorway exit in the 1980s.

Instead of a general renovation of the original bridge with the one-way lanes, which had become due, the structure was rebuilt between March 2011 and August 2012 after an interim renovation in 2009: first the one-way lane Vienna (opened on November 27, 2011), followed by the one-way lane Munich (opened 9 September 2012). The old 1200 ton steel structure and 1850 m³ of concrete were removed and a new steel frame of 950 tons was built. In the course of the redesign of the bridge, two kilometers of the adjoining carriageway to the east towards Vienna to the Söllheim valley crossing were also completely renovated. The work was carried out by Teerag-Asdag , a Porr company .

As is well known, the Kasern valley crossing has served several times as a residence for people without a permanent residence, including in one case for a whole family, most recently for homeless beggar migrants. In such cases, ASFINAG, as the maintainer of the bridge, will clear the bridge.
