The Vienna outer ring expressway S 1 is an expressway in Austria and an important part of the regional ring around Vienna . When completed, it should lead around the federal capital in an eastern semicircle and relieve the city motorways.

The south and north bypasses, which opened between 2006 and 2010, are currently in operation. The southern part connects the A 2 south autobahn and the A 21 outer ring autobahn from the Vösendorf junction with the A 4 east autobahn at the Schwechat junction . The northern section begins at the transition from Vienna's north edge expressway S 2 at Süßenbrunn and leads via the Eibesbrunn junction with the A 5 north autobahn to the Korneuburg junction with the A 22 motorway on the Danube currently in planning.

In terms of road traffic law, the S 1 has the status of a motorway and requires a vignette or toll . Operation and maintenance is carried out in the Vösendorf - Schwechat section by ASFINAG , and in the Süßenbrunn - Korneuburg section by Bonaventura Straßenerhaltungs-GmbH .

meaning

Proponents hope that the S 1 will greatly relieve the busy Vienna south- east bypass A 23, while the opponents fear a rapid increase in transit on adjacent motorways. Nature conservation organizations tried again and again to delay the construction through legal proceedings and appeals .

In fact, traffic on the tangent has decreased significantly since the opening of the first section of the S1 between Vösendorf and Schwechat. Since then, up to 60,000 vehicles or a third of the trucks have been on the A 23 less. Especially for west-east traffic, the S 1 is a significantly faster connection than the A 23 and the Vienna city area.

Along the S 1 there are nationwide driving bans for trucks over 3.5 tons on low-ranking roads in order to ban transit traffic from the towns and to prevent toll refugees.

Route sections

Vösendorf – Schwechat (southern bypass)

The 16.2 km long route between the Vösendorf junction (A 2, A 21) and the Schwechat junction (A 4) was originally planned in the 1940s. But only with the construction of the A 21 , the new planning as "B 301" started again. In the meantime, large parts of the original route had already been built, so that not only had numerous plots to be redeemed, but also underground tunnels (e.g. in the Rannersdorf area ).

On October 25, 2001, construction work finally began on the 16.2 km long “S 1-Süd” from the Vösendorf junction to the Schwechat junction . The route runs alternately in the area of Vienna and Lower Austria , leads through five tunnels and is connected to the subordinate road network via eight junctions.

On December 10, 2004, the first section between Schwechat-Süd and -Est could be released, on March 4, 2005 the section to the Schwechat junction followed. The Vösendorf – Schwechat line was fully approved on April 28, 2006.

Is the between junctions Leopoldsdorf and Rannersdorf Raststation Schwechat .

In 2014/15 the junction for the Inzersdorf freight terminal (4) was built.

Schwechat – Süßenbrunn (eastern bypass, in planning)

The S 1 is to be extended from the Schwechat junction (A 4) north to the Süßenbrunn junction (S 1) . This part is also known as the “northeast bypass” and was previously planned as the B 305 . There were several variants to choose from. In March 2005, the decision was made to run the S 1 under the Danube into Lower Austria and further along the city limits from Vienna to the north.

The planned route runs east of the Freudenau power plant under the Danube and under the Donau-Auen National Park through an 8.2 km long two-tube tunnel. Each of the two tubes, each 15 m in diameter, is to have two lanes and a hard shoulder. The bottom of the tunnel will be about 50 m below the surface and thus below the gravel layers in the silt . Insofar as tunnel construction is carried out using the mining method , special "closed tunnel boring machines " are intended to prevent drainage or contamination of the groundwater. The tunnel sections to be constructed using the open construction method will be carried out in sections in closed, sealed construction pits in order to keep the lowering of the groundwater level as low as possible.

To increase traffic safety, the tunnel tubes will have cross- passages that can be walked on at intervals of 500 m and cross-passages that can be driven over at intervals of 1000 m , and a general speed limit of 80 km / h will apply. Since no technical buildings are allowed to be erected in the area of ​​the nature park, the tunnel is ventilated at its portals.

The construction will take place in two sections from Süßenbrunn to Groß-Enzersdorf and from Groß-Enzersdorf, crossing the Lobau and Danube , to the Schwechat junction . The construction of the section from Süßenbrunn to Groß-Enzersdorf is to begin at the same time as the first section of the Marchfeld expressway . If the original start of construction was planned for 2014 and completion in 2016, the second half of 2016 was announced as the new construction start in July 2014, and the completion date in 2018.

The second section between Groß-Enzersdorf and Schwechat is to begin in 2018 and could be completed in 2025. After an appeal was lodged against the approving decision in the EIA procedure on March 27, 2015, it was tried again before the Federal Administrative Court . According to EIA law, the building project was approved again in May 2018. Tunnel opponents appealed against this decision to the Administrative Court , the procedure is still open (as of August 2019). A nature conservation organization also lodged a complaint against the nature conservation law approval notification from the City of Vienna, which the Federal Administrative Court must now decide on.

There were also considerations of building a cheaper bridge over the Danube instead of the Lobau tunnel.

Süßenbrunn – Korneuburg (northern bypass)

Following the Vienna north edge expressway S 2 near Süßenbrunn , the S 1 was built between 2007 and 2009 to the north motorway A 5 at the Eibesbrunn junction . In between is the Seyring junction , for which a separate feeder road , the so-called Spange Seyring , was built. On the approx. 10 km long route from Süßenbrunn to Eibesbrunn, the S 1 passes under both the Northern Railway and the Laaer Eastern Railway in the form of tub structures . The opening to traffic of this section, which bore the name "S 1-East" during the construction period took place on 31 October 2009. The rest stop German-Wagram was opened between autumn 2010 and June 2011th

Until the opening of the S 1 section between Groß-Enzersdorf and Süßenbrunn, the section between the planned Süßenbrunn junction and the Vienna / Lower Austria border , north of the Süßenbrunn junction , will be part of the S 2 expressway north of Vienna . Since 2014 this street has also been called "S 1".

Following the Eibesbrunn junction , the S 1 leads to the Danube bank A 22 motorway at the Korneuburg junction . This 13.5 km long section runs about halfway in the tunnel and is called "S 1-West".

After the original route ordinance for this area was repealed by the Austrian Constitutional Court due to a formal error in summer 2007, the EIA procedure had to be carried out again. However, since all the reports from the previous procedure were already available, this could be brought about in a much shorter time than usual. Since December 27, 2007, the course of the "S 1-West" has been fixed again by a decision from the Federal Ministry for Transport, Innovation and Technology .

The "S 1 West" is led through three tunnels. The two underground routes, Kreuzenstein and Stetten , were built using the cut- and- cover method, while the Tradenberg tunnel is the first tunnel to be built by miners in the Weinviertel. After 37 months of construction, the S 1-West was opened to traffic on January 31, 2010.

Both sections (S1 East and West) as well as the Northern Highway and the S 2 "bypass Süßenbrunn" as part of the PPP eastern region through a Public Private Partnership model of the Bonaventure Road-GmbH (a consortium of HOCHTIEF PPP Solutions GmbH , ALPINE Bau GmbH and Egis Projects ) and then operated for 30 years by Bonaventura Straßenerhaltungs-GmbH .

Spange Seestadt Aspern (planned)

According to the original plans, the high-level connection to the Seestadt Aspern should have been made by extending the A 23 (south-east bypass) from the Hirschstetten junction to the Raasdorf S 1 junction . Due to an amendment to the Federal Roads Act of July 29, 2011, this was rejected and instead only the section from the Raasdorf junction to the Heidjöchl junction will be built as part of the S1 . The connection S 1 Heidjöchl - A 23 Hirschstetten will be expanded by the municipality of Vienna as a four-lane city ​​street , for which the city of Vienna will receive special subsidies from the federal government. The Spange Flugfeld Aspern will have a length of 4.6 km. The line will run from the Raasdorf junction immediately north next to the Marchegger Ostbahn . A green bridge over the road and railway line is planned between the junction of Telefonweg and Flugfeld Aspern at Cassinonestrasse . The Spange Flugfeld Aspern will be built with structurally separate directional lanes, each with two lanes and one parking lane. The start of construction is planned for 2020/21, the traffic opening for the year 2024, the costs are estimated at 223 million euros.

technology

Due to its equipment, the S 1 is considered the most modernly equipped motorway or expressway in Austria. Overhead signposts in the form of prismatic reversers and LED displays are installed along the entire route , which can use a traffic control system to show the driver different routes, information, speed restrictions and other messages depending on the traffic situation. They are all automatically controlled from the control center in Vienna-Inzersdorf.

Pump systems have been installed in the three tunnels of S 1 South to pump out any rainwater.

criticism

Structural criticism

Schwechat node

Immediately after the opening of the Vösendorf - Schwechat section, there was severe criticism of the connection to the A 4 at the Schwechat junction. The previous Schwechat junction was not expanded in the course of the construction of the S 1 South in order to avoid traffic obstructions on the A 4. The existing junction was designed as a double curve but with very tight curve radii.

Immediately after the opening of the S 1, serious accidents very often occurred at the Schwechat junction. Despite the subsequent decree of the speed limit to 60 km / h, the road users at the Schwechat traffic junction drove too fast for the curve radius there, which resulted in numerous accident victims and ultimately also fatalities. Even roughening the road in the danger area did not help because of the combination of tight curve radii and speeding. After a fatal accident, the original plan was discarded and the renovation began immediately, which was completed in December 2006.

Signage

Another point of criticism is that the signs, especially for speed limits, are very confusing. On the one hand, remote-controlled variable traffic signs are mounted on overhead bridges. There are also restrictions for trucks with additional panels.

Wrong-way drivers

The conversion of both the S 1 and the A 4 led to a record of “ghost” drivers in the first few months after the openings (16 in just four months). The reason given by the motorway police is that most of the "ghost" drivers drive past interchanges due to excessive speed and then turn around or push back on the expressway.

Conservation Concerns

With the planned extension of the S1 in the Lobau area, there are concerns that although the traffic itself runs underneath, the exhaust gases from the tunnel are led out in the middle of the nature reserve.

For these and other reasons there are always citizens' initiatives against the extension to the north. In December 2006, for example, the area where test drilling is being carried out was occupied by demonstrators and construction companies were prevented from drilling. It was only after eight weeks that this could be carried out after ASFINAG threatened to take legal action and a round table had been promised , in which environmentalists should also take part.
