The Steyrtal Straße (B 140) is a state road in Upper Austria . It runs over a length of 25 km through the valley of the Steyr , a left tributary of the Enns .

course

The Steyrtal Straße branches off from the Voralpen Straße (B 122) in Sierning near the town of Steyr and leads to the foot of the Sengsengebirge . In the local "Steinwänd" (municipality of Micheldorf ) it flows into the Pyhrnpass Straße B 138. The road always runs on the left bank of the Steyr and follows the course of the former Steyrtalbahn .

Buildings

The narrow and confusing Ober Grünburger local passage is bypassed to the west by a 1165 meter long tunnel. The north portal is at the bridge over the Harrbach, shortly after the museum station Grünburg, the south portal at the confluence of the Schiefer Landesstraße.

The largest bridge structure is the Steyr breakthrough valley crossing (also Steyr breakthrough bridge), completed in 1969, along the Steyr over the Tiefengraben . The prestressed reinforced concrete structure is 205 m long and 12.66 m wide. The greatest height is 35 m. To the right of it, the Steyrtalradweg leads over the Tiefengrabenbrücke of the Steyrtalbahn, built in 1908. The span of this arch bridge is 80 m, the clear height 40 m.

history

The road was expanded in 1865. The so-called “Roman Bridge” in the Tiefengraben near Steyrbruchbruch dates from this time.

The Steyr- Leonsteiner Landesstraße has been known as the Steyrtalstraße since 1932 , when the beginning between Steyr and Sierninghofen was divided into the Voralpenstraße . After the annexation of Austria , the Upper Austrian road network was reorganized according to the German model. On April 1, 1940, Steyrtalstrasse was declared a state road of the first order and designated LIO 21. The Steyrtal Straße (spelling from 1948) has been part of the network of federal highways in Austria since January 1st, 1950 .

The road section of the Römerbrücke was abandoned when the Steyr breakthrough valley crossing was completed in 1969.

1973–83 the Sierning bypass was built , with the new connection to the Voralpen Straße (B 122). The old beginning in Sierninghofen became obsolete, but the street Neuzeug - Steinfeld - Pichlern is still called Steyrtalstraße today . The new beginning to Pichlern is near Frauenhofen .

Since April 1, 2002, Steyrtal Straße has been under state administration again.

The exploratory tunnel for the Grünburg tunnel was completed in July 2003. Since Obergrünburg is already in the flysch zone , the construction work turned out to be lengthy and complicated. The bypass tunnel has been open to traffic since June 8, 2008.
