History

Freistadt In the first draft of an Austrian road network of Leopold Oerley, a university professor at the Technical University of Vienna, in 1936 for the first time to connect - (- Budweis Prague) - Linz was intended. The press officer of the German Association HaFraBa, Kurt Kaftan, looking in his study "Europe needs Highways " also, the route Prague - Ceske Budejovice - Linz ago. A year later, contained the draft August Schmöllers, later head of the State Office for Spatial Planning for the Upper Danube in the Third Reich, also a connection from Linz to the Czech border at bottom forest, a town in the municipality Windhaag bei Freistadt ago. Also, the highway plan by Alfred Sighartner of the same year saw a route from Prague through Budweis to Linz before, but not as a motorway.

After the invasion of the German army in Austria in March 1938, neither the plans dated 13 March, nor from December 15, 1938 contained a motorway link from Linz Budweis to Prague. Although the track was edited by planners since the annexation of the Sudetenland, it is not listed in network plans the years 1939/40. In June 1940 a plan was present, further comprising a branch in Ebelsberg of the Western Highway and the leadership of the route on Weikerlsee passing over a bridge over the Danube, Gallneukirchen, Silly village in the Riedmark, Ottenschlag in Mühlkreisautobahn, Schenkenfelden, rich valley, Foundation with the rich valley to Ceske Budejovice envisaged.

During this stretch, the east led past the motorway at Linz, was not released for construction, was thinking of the West highway at a feeder route as linking the city of Linz. This should from today Linz junction of the motorway Salzburg - Vienna branch off and run on today's route of the A 7 to the level of the node Linz- Hummelhof. Finally, the line should result in a straight course during Blumauerplatz on Linz's main train station to the Vienna road. From Linz to Salzburg node of the feeder road should be designed as a highway, to be subsequently applied as a monumental road 65-105 meters wide. In the section between the nodes Linz and Salzburg AS road was begun with the construction of ten bridges that no longer, however, came to completion.

Between 1954 and 1956, it was examined how the city of Linz could be connected to the western highway. The decision was finally made for the resumption of construction work at a feeder. This first major section of the Linz junction to junction Salzburger Straße (AS Linz -Süd) was opened on 24 October 1964.

The section between the nodes Hummelhof and AS Urfahr was first provided in the General Transport Plan of the City of Linz in 1957 as a motorway- expressway. The implementation began in April 1961. Between 1962 and 1979, these parts of the highway in the city of Linz was opened to traffic.

Only with the amendment to the Federal Highway Act in 1968 found the Mühlkreisautobahn highway to the Czech border, then still called Pyhrnautobahn, entrance into the highway plans of the Republic of Austria. Accordingly, the continuation of the highway from AS Urfahr was included in the overall transport plan of the city of Linz in 1972. Between 1974 and 1982 by the building of the highway between AS Urfahr and today's end of the motorway.

In the 1970s, the Mühlkreisautobahn highway across the area west of Neumarkt in Mühlkreisautobahn and Summerau was ( west Freistadt) planned to the state border, but rejected because of ecological and hydrological reasons. 1983 A 7 was painted between the end of the motorway at Unterweitersdorf and the state border from the Federal Highway Act. Instead, a " Mühlkreisautobahn highway " (S 21) was to be built. Background of these changes were traffic forecasts for the section that did not justify the construction of a highway. In fact, financial considerations played a role. With the Federal Highway Act Amendment 1986, the section was finally downgraded to run as a B 125 " Prager Straße ".

The political changes in the Czech Republic and the opening of borders, the traffic volume rose in said section to the existing national road considerably. In 1993, the Czech Minister of Transport in January Strasky also announced the construction of a highway from Prague on the border at Budweis Wullowitz. In 1999, the route was therefore as B 310 " Mühlviertler Street " in the Federal Highways Act, Schedule 3 ( highways ) was added, after which " connections of public roads, [ ... ] to run in the open field only in the form of special connection points " were allowed. 2002 B was 310 in the directory 2 - transferred to the Federal Road Act as S 10 - Federal highways.

Currently lead the remaining 36 km to the border on the Mühlviertler road (B 310). In future, these by the Mühlviertler Expressway ( S 10) is to be replaced, the route runs to the east of Freistadt. With the work on the section of Unterweitersdorf to Freistadt North was begun in 2009 and in September 2012 was the opening to traffic of the subsection 1 at Unterweitersdorf. ( - Venice over the Phyrn and thus Berlin) closed - On the Czech side is then combined with the Dálnice 3 axis Prague Linz.

The A 7 counts in the city of Linz with an average of 63 790 vehicles per day on the busiest sections of road in Upper Austria. To reduce the noise pollution for local residents, it was housed in the densely populated neighborhoods Bindermichl Spallerhof and Niederhart. Traffic has since November 2005 through two tunnels with 1062 and 580 meters in length, which were built in less than two years of construction and were controversial due to high costs.
