The autobahn Südosttangente Vienna A 23 , colloquially known as the Südosttangente or Tangente , is an urban freeway in Vienna and part of the European roads E49 , E59 and E461 . With a length of almost 18 kilometers, it is the shortest autobahn , but with an average frequency of 170,000 vehicles per day, it is the busiest road in Austria . The name is derived from the role of the connecting road between the south motorway (A 2) and the east motorway (A 4).
location
The motorway runs from Altmannsdorfer Straße in a south-eastern tangent around the city center and then swings north where it joins the Vienna Nordrand Expressway at Hirschstetten . It crosses the south , east and Danube bank autobahn . The Prater Hochstraße runs in an elevated position through the recreational area of the Wiener Prater , the subsequent Prater Bridge crosses the Danube as one of the 12 Viennese Danube bridges . As is customary on motorways in Vienna, there is a speed limit of 80 for passenger cars and a limit of 60 km / h for trucks over 7.5 tons on the entire A23 .
history
On December 19, 1970, the first section between the Inzersdorf junction and the Vienna- Favoriten junction was opened, three days later the section between the Kaisermühlen junction and the Prater junction.
The other sections between Favoriten and the Prater junction and the Altmannsdorfer Ast followed by 1978 . On June 29, 1993, the so far last section between the Kaisermühlen junction and Hirschstetten as well as the Viennese north edge federal road B302 to Wagramer Straße , which adjoins the A23 , was opened. Since 2002, this street has been called the Wiener Nordrand Schnellstraße S2. In 2009, this level was expanded and extended to the Vienna outer ring expressway S1 near Süßenbrunn .

As early as 1979 there were plans to connect the A23 with the North Autobahn via a “north-east bypass ” A24 . This road has nothing in common with the later planned and abandoned A24 .
Traffic importance
The Vienna Südosttangente is the busiest road in Austria and one of the busiest in Europe. Due to the high volume of traffic and frequent truck accidents, there have been long traffic jams in the past . That is why it is often jokingly referred to as the largest parking lot in Austria . With the opening of the Vienna outer ring expressway S1 in May 2006, the A23 between the Inzersdorf junction and the Prater junction was significantly relieved. The section from the Prater junction to the Kaisermühlen junction, which is not relieved by the S1, is currently the most frequented section of the road in Austria as the bottleneck , as all long-distance traffic from south / east to north rolls over this route and this is particularly true despite four lanes in each direction causes delays in rush hour. The further expansion of the S1 from Schwechat to Süßenbrunn would be an alternative to this section, especially for long-distance traffic to and from the A5 north motorway.
General
The fly-over was developed and successfully used for several years in order to be able to repair the expansion joints on the bridges that had become damaged during the years of heavy loading without a total lock . Capacity expansions are also ongoing. In 2005, the A23 between Sankt Marx and the Prater junction was expanded to four lanes in each direction.
The A23 is not always equipped with hard shoulders. In the Kaisermühlen – Hirschstetten section, there are no emergency lanes, there are only a few breakdown bays .

Seestadt Aspern section
It was planned to connect the Seestadt Aspern in the 22nd district via the A23. From the end of the autobahn at Hirschstetten , the south- east bypass should be extended along the Marchegger Ostbahn to the planned Vienna outer ring expressway S1 at Raasdorf .
In November 2010 it was announced that only the section from the Raasdorf junction (S1) to the Heidjöchl junction will be implemented as part of the S1 between 2015 [obsolete] and 2017 [obsolete] . The Heidjöchl – Hirschstetten (A23) route is being expanded as a four-lane city road by the municipality of Vienna . The federal government grants special grants to the City of Vienna for the construction as a state road, due according to the progress of construction.
Video surveillance
Since December 12, 2007, a so-called “Automatic Vignette Control” (AVK) has been taking place on the Vienna Südosttangente by means of video surveillance ; it is the first such facility in Austria. According to the operating company ASFINAG , their location should change regularly in the future following a sample plan.
Route
Altmannsdorfer branch
The " Altmannsdorfer Ast" is the extension of the A23 from the Inzersdorf junction towards the west, where it joins the Altmannsdorfer Straße (B224) after about 2 km . Together with the B1 and B224, the Altmannsdorfer Ast represents a connection from the Tangente to the West Autobahn to Auhof and an alternative to the Vienna Outer Ring Autobahn (A21).
Inzersdorf node
The Inzersdorf junction connects the tangent with the south autobahn (A2) and is designed in the form of a broken autobahn triangle . The Inzersdorf and Triester Straße junctions are also located within this. The south-west connection of this node belongs to the A2, while the west-east and south-east connections belong to the A23. The Inzersdorf junction is a TOTSO junction. Coming from Altmannsdorf on the A23, you have to turn off in the direction of Favoriten, straight ahead you get to the A2. Coming from the south on the A2, you can also go straight on to the A23 heading north, while the remainder of the south autobahn heading west - including the A2 junction Triester Straße - has to be turned right.
The Inzersdorf node was completely renovated from 2012 to 2018 together with Hochstraße Inzersdorf . Large parts of the route, which ran on stilts, were placed on a newly constructed dam.
Hansson curve
In the section between the Inzersdorf junction and the Favoriten district, there is the “Hansson curve”, a 90 ° curve on which the A23 swings from west to north. Accidents and traffic jams have occurred time and again in the past . The unofficial name known from traffic radio got the curve from the neighboring settlements of the same name, the Per-Albin-Hansson-Siedlung Ost , West und Nord, which were named after the Swedish post-war politician Per Albin Hansson .
This section was extensively renovated from 2011 to 2012 up to the Laaerberg tunnel and the tunnel safety was brought up to date.
Asfinag planned to set up a connecting clasp from the Hansson curve in a southerly direction to the Vienna outer ring expressway (S1). This route was laid down as the Rothneusiedl (A24) motorway link in the Federal Roads Act, but was removed from the Federal Roads Act on July 29, 2011. This should, among other things, relieve the Laxenburger Strasse.
Favorites
After the Hansson curve, the A23 initially ran in a right-hand curve along Saligergasse to Favoritenstrasse, where the Favoriten junction was. After the opening of the Favoriten , the second largest roundabout in Vienna, the old junction was dismantled. A short part of the carriageway of the section opened in 1970 is still there and serves as a storage area.
In the area of the new Favoriten junction, the tangent passes under the Favoriten distribution circuit as part of the Laaerberg tunnel . The main roads B16 and B225 intersect here . The Absberg tunnel is located north of the junction .
Arsenal junction ("closed Simmering exit")
The plans of 1978 envisaged a connection of the southeast motorway (A3) to the tangent in this area . The access and exit ramps had already been set up when this project was abandoned for cost reasons and because of citizen protests and instead the A3 was connected to the South Autobahn ( A2) at the Guntramsdorf junction . In 2005, during construction work on the main carriageway, the northern access and exit ramps served as a diversion route. Later plans envisaged expanding the junction known colloquially as the “blocked Simmering exit” into a junction with Wienerberg Strasse (B 225) by 2007 and, after further delays, until 2011 , but this project was also stopped for budget reasons. The ramps, which have no connection to the subordinate road network, are now used to reverse operations for maintenance, winter service and emergency vehicles as well as for filming. The "closed Simmering exit" will be partially demolished and rebuilt in 2020 as part of the renovation of the lanes. After the renovation, it is available to the emergency services.
Belt / country road
The belt / country road junction was actually designed as a node to which the belt motorway, which was never realized , was to be connected. It is executed in a dissolved form and has two ramps from the belt on the tangent to the north, each of which lead from the left and right onto the A23 and a ramp from the belt to the tangent to the south.
The Landstraßer Gürtel ( B221 ) between the main train station and the Landstraße junction was expanded between November 2010 and March 2013. As part of this construction work, the connection Landstraßer Gürtel - A23 was built level-free , as an underpass . Landstraßer Hauptstrasse (B221) from the A23 junction to Rennweg was also expanded.
26 June 2012 was opened with the "wild goose tunnel" a first section, which traffic from the A23 to Landstraßer main street housed leads. The “Eurogate” underpass from the Gürtel to the A23 was opened to traffic on March 28, 2013. As the last section, the complete renovation was completed on October 29, 2013. The total costs are estimated at 101 million euros, which are provided by the City of Vienna and ASFINAG.
Saint Marx
The area around the Sankt Marx junction was the most heavily frequented section of the tangent until the opening of the Vienna outer ring expressway (S1). The junction leads to the Erdberg industrial area, where the Sankt Marx slaughterhouse was located.
Prater node
The Prater node is designed in the shape of a clover leaf . Here the A23 intersects with the Ost Autobahn (A4). In the course of the knot, the tangent on the Erdberger Bridge crosses the Danube Canal. As one of the busiest bridges in Austria, ASFINAG planned to demolish and rebuild the bridge, as renovation was not an option. At the suggestion of the builder Alfred Pauser , however, the Federal Monuments Office checked whether this bridge should not be placed under monument protection.
After a negative decision by the Federal Monuments Office regarding monument protection became known in January 2013 , work has been going on since March 2014 to erect the replacement bridges, which started traffic while the main bridge was being demolished. These bridges remained after the construction of the new Erdberger Bridge as part of the Prater junction in order to disentangle the traffic. The renovation was originally supposed to be completed by the end of 2017. By using a special ship as a support structure for the parts of the old bridge to be demolished, the time planned for the demolition could be drastically reduced. The new Erdberger Bridge was opened to traffic at the end of August 2016 and all work in the junction area was completed by the end of 2016.
Prater Hochstrasse
The Prater Hochstrasse lies between the Prater junction and the Handelskai junction and crosses the Wiener Prater recreational area . With 171,454 vehicles daily, it is the busiest section of road in Austria. Between 1998 and 2000, this section was completely refurbished, the supporting structures widened and expanded from six to eight lanes and equipped with hard shoulders and the most modern safety devices.
Handelskai
The Handelskai junction leads to Klosterneuburger Straße (B14) and provides, among other things, the connection from the tangent to the exhibition grounds , the Ernst Happel Stadium and the Freudenau harbor .
Prater Bridge
In the course of the Prater Bridge , the A23 crosses the Danube , Danube Island and New Danube . In 1996/97 the Prater Bridge was raised by 1.8 meters due to the construction of the Freudenau power plant and expanded from three to four lanes in each direction.
Kaisermühlen knot
At the Kaisermühlen junction there is a connection from the tangent to the Donauufer Autobahn (A22), to Donaustadtstrasse (B3b) in the direction of Kagran and to Raffineriestrasse in the direction of the Lobau oil port . The junction is set up in the form of a roundabout into which most of the connecting ramps lead. The A23 ended here until 1993, when the extension to Hirschstetten was opened to traffic. Even today, the phrase "tangent towards Kagran" is used in traffic radio.
Stadlau
The semi-junction Stadlau connects the A23 south with the Donau Straße (B3) in the direction of Groß-Enzersdorf . A full expansion is currently not planned, if you want to go from the north to Stadlau, you have to leave Hirschstetten.
The junction is between the Stadlau tunnel and the Hirschstetten tunnel , in the course of which the A23 passes under the Stadlau freight station and the Laaer Ostbahn . Both the exit and the access ramp are located in the tunnel. This section was extensively renovated between 2016 and 2017.
Hirschstetten
The tangent ends at the Hirschstetten junction and joins Vienna's northern edge expressway (S2). The transition is exactly in the middle of the bridge over Hirschstettner Straße, so strictly speaking only the exit and access ramp to the south belong to the A23, those to the north already belong to the S2.
In the course of the originally planned extension of the A23 towards the Seestadt Aspern, a Hirschstetten junction was planned at this point. Instead, according to the planning status in 2018, the city road Aspern should connect the A23 via the Seestadt with the S1 near Großenzersdorf in a similar course.
