The Mühlkreis Autobahn A 7 is a motorway in Upper Austria and part of the Europastraße 55 . It runs from the Linz junction on the West Autobahn (A 1) through the city of Linz northwards into the Mühlviertel and ends after 28 km in the Unterweitersdorf municipality at Kalchgruberweg, where it merges seamlessly into the Mühlviertler Schnellstraße (S 10).

history

In the first draft of an Austrian trunk road network by Leopold Oerley , professor at the Technical University of Vienna , from 1936, a connection ( Prague - Budweis -) Freistadt - Linz was considered for the first time . The press officer of the German HaFraBa association , Kurt Kaftan, also envisaged the Prague - Budweis - Linz route in his study "Europe needs motorways". A year later, August Schmöller's draft, later head of the regional office for regional planning for the Upper Danube region in the Third Reich, also contained a connection from Linz to the Czech border near Unterwald , a town in the Windhaag community near Freistadt . Alfred Sighartner's road map from the same year also provided for a route from Prague via Budweis to Linz, but not as a motorway.

After the German army marched into Austria in March 1938, neither the plans of March 13, nor of December 15, 1938 contained a motorway connection from Linz via Budweis to Prague. Even if the route has been worked on by planners since the annexation of the Sudetenland, it is not yet included in network plans from 1939/40. In June 1940 there was a plan that would branch off the West Autobahn at Ebelsberg and route the route past Weikerlsee over a bridge over the Danube, Gallneukirchen , Alberndorf in Riedmark , Ottenschlag in the Mühlkreis , Schenkenfelden , Reichenthal , Stiftung bei Reichenthal on to Budweis provided.

While this stretch, which the Autobahn led past Linz to the east, was no longer approved for construction, a feeder route was intended to connect the city of Linz to the West Autobahn . This should branch off from the Salzburg - Vienna motorway from today's Linz junction and lead on the current A 7 route to the level of the Linz-Hummelhof junction. After all, the line should flow straight into Wiener Straße at Blumauer Platz at Linz Central Station. From the Linz junction to Salzburger Strasse, the feeder should be designed as a motorway, and then be laid out as a monumental road 65 to 105 meters wide. The construction of ten bridges began in the section between the Linz junction and AS Salzburger Straße, but these were never completed.

Between 1954 and 1956 it was examined again how the city of Linz could be connected to the West Autobahn . The decision was finally made to resume construction work on the feeder. This first large section from the Linz junction to the Salzburger Straße junction (AS Linz-Süd) was opened on October 24, 1964.

The section between the Hummelhof junction and the Urfahr AS was initially intended as a motorway-like expressway in the general traffic plan of the city of Linz from 1957. Realization began in April 1961. Between 1962 and 1979, these parts of the motorway in the city of Linz were opened to traffic.

It was not until the amendment to the Federal Roads Act in 1968 that the Mühlkreis Autobahn to the Czech border, then known as the Pyhrn Autobahn, was included in the motorway plans of the Republic of Austria. Accordingly, the continuation of the motorway from AS Urfahr was included in the overall traffic plan of the city of Linz in 1972. Between 1974 and 1982 the construction of the motorway between AS Urfahr and today's end of the motorway took place shortly before Unterweitersdorf . The end of the autobahn was rebuilt several times, as the original three sharp bends were the undoing of some trucks. From the continuation, the earth wall to the center of Unterweitersdorf is still preserved, but this has been recultivated in the meantime.

In the 1970s the Mühlkreis Autobahn was planned over the area west of Neumarkt im Mühlkreis and Summerau (west of Freistadt) to the state border, but was discarded for ecological and hydrological reasons ( Gusental along the former horse-drawn railway). In 1983 the A 7 between the end of the autobahn at Unterweitersdorf and the state border was deleted from the federal highways law. Instead, a "Mühlkreis Schnellstraße" (S 21) should be built. The background to these changes were traffic forecasts for the section, which did not justify the construction of a motorway. In fact, financial reasons also played a role. With the amendment to the Federal Roads Act in 1986, the section was finally downgraded for execution as B 125 “Prager Strasse”.

With the political change in the Czech Republic and the opening of the borders, the volume of traffic in the section on the existing federal road increased significantly. In 1993, the Czech Transport Minister Jan Stráský also announced the construction of a motorway from Prague via Budweis to the border at Wullowitz. In 1999 the route was therefore included in the Federal Roads Act, Directory 3 (Federal Roads) as the B 310 "Mühlviertler Strasse", according to which "connections to public roads and paths [...] in the open air were only allowed in the form of special junctions". In 2002 the B 310 was transferred to Directory 2 - Federal Highways - of the Federal Roads Act as S 10.

Work on the Mühlviertel expressway (S 10) for the section from Unterweitersdorf to Freistadt-Nord began in 2009. These were completed in autumn 2015. An extension to the state border is currently being planned; the remaining 15 km to the border are currently via Mühlviertler Straße (B 310). On the Czech side, the Dálnice 3 will close the Prague - Linz axis (and thus Berlin - Venice over the Pyhrn ).

With an average of 63,790 vehicles per day, the A 7 is one of the busiest road sections in Upper Austria in the urban area of ​​Linz. In order to reduce the noise pollution for the neighbors, it was enclosed in the area of ​​the densely populated districts of Bindermichl , Spallerhof and Niedernhart . Since November 2005, traffic has passed through two tunnels with a length of 1062 and 580 meters respectively, which were built in just under two years and which were controversial due to their high costs.
