History

General

The motorway is a new building, which was started in 1996 with the main portion Erfurt -Schweinfurt as part of the German Unity Transport Project No. 16. It is, apart from a brief slope section between the tunnel and Behringen Ilmenau -Ost, going through four lanes (plus emergency lane, outside the tunnel ) and has a standard cross-section (RQ ) of 26 m width. With about ten million euros per kilometer, the track is one of the most expensive streets that were built in Germany. The first section of Erfurt Bindersleben to the temporary connection Traßdorf 1998 was opened to traffic in 2001 was followed by the section to Ilmenau -Ost and the section between junctions Oberhof and Suhl / Zella- Mehlis.

In December 2002, Section Suhl / Zella- Mehlis to Meiningen - North has been released. In the summer of 2003, the stretch of Erfurt was in operation until Meiningen -south. Was on 14 October 2005 in advance of the section between the interchange Werntal at Schweinfurt, where the A71 joins the A70 and the junction Bad Kissingen / Oerlenbach opened to traffic. On 17 December 2005, the section of Meiningen -South followed - Bad Kissingen / Oerlenbach, so the 1.6 billion € expensive and 152 km long section between Erfurt and Schweinfurt was completed. The remaining portion to Sangerhausen to be opened to traffic by 2014. At this time are expected on the day on the new route 35000-45000 cars.

Thuringian Forest Highway

In the section Arnstadt -South North - Meiningen with about 60 km of the highway traverses the Thuringian Forest at its narrowest point and has also the name of the Thuringian Forest Highway. The actual ridge crossing is at 670 m above sea level with a maximum gradient of two percent in almost eight kilometers long Rennsteig Tunnel as the longest highway tunnel in Germany. He is locked for transport of dangerous goods. A release is not foreseeable.

Speed limit

Between the tunnels Old Castle and mountain goat, there are over a length of about 18 kilometers an indicated with traffic signs speed limit of usually 80 km / h, which is monitored by five fixed measuring points in each direction. These lie in the Rennsteig Tunnel at km 117 and 120, between Hochwald tunnel and tunnel Bergbock at kilometer 125 and the tunnel Bergbock at kilometer 128 There is also before the tunnel Ancient castle at kilometer 112 and 113.5 a speed and distance measuring system. Here is an unapproved license plate detection system was tested in 2003. Another distance measuring system is coming just before the tunnel Alteburg from Erfurt. On both systems, the speed is also recorded to determine the safety distance.

Restructuring in existing road network

After the construction of the A71 some parallel main roads were closed or downgraded:

  • The B 4 was graded between A 71 -AS Erfurt- Coburg and Gispersleben to the state road or county road.
  • The B 7 was graded between A 71 -AS Erfurt Bindersleben and Erfurt Linder Bach to the county road. At the same time the four-lane L was 1052 ( eastern bypass Erfurt) from junction Linder Bach to A71- AS Erfurt-Nord rededicated to B7.
  • The B 19 was graded between Meiningen and Muennerstadt and between Euerbach and the A - 70 AS Werneck from national road 3019 ( in Thuringia ) and State Road 2445 ( in Bavaria).
  • The B 86 was in 2013 between the AS Heldrungen and Saxony castle to country road 3086, in Heldrungen for county and township road, downgraded. The section of the AS Heldrungen to A 38 AS Sangerhausen -South is to follow. The Federal Highway 85 and State Road 176 should also be likewise restructured.
  • The B 87 was downgraded in 2013 between the AS Ilmenau Ilmenau -Ost and the location to the highway 3087.
  • The B 88 was downgraded to the country road to the municipal road and between the AS Ilmenau -Ost and AS Ilmenau- West between the AS Ilmenau- West and AS Gräfenroda.
  • The B247 was downgraded between Ohrdruf and Schleusingen for L 3247.
  • The B 280 of Zella- Mehlis to Meiningen was between Zella-Mehlis and Benshausen to B 62, on to the main road to 1131 and County Road 581

The B 19 was newly built and installed in the room Meiningen part. She now leads from Meiningen Meiningen Helba for AS -Nord. From the AS Muennerstadt to the confluence of the B 287 B 19 is replaced by the B 287.

On the other hand, several major road projects for the hinterland connections of A 71 are planned, under construction or implemented:

  • In Artern a bypass (L 1172 ) was to improve the accessibility of the eastern areas around Roßleben to the motorway.
  • Heldrungen also received a bypass (L 3086 ), which improves the binding of Bad francs Stockhausen.
  • Also in Sömmerda a bypass (B 176) was constructed, which improves the traffic from the A71 to the west. In further stages of construction here is the road network to Weissensee and Straußfurt be reorganized (with new bypass of B 4).
  • In Erfurt the east ring road was built ( now part of the national highway 7) of the Erfurt new ring from the A to the B 71 to 7 in the direction of Weimar.
  • Between Straußfurt and Bad Langensalza the federal highway 176 was laid on a route further south from Andisleben to improve access north-west of Thuringia to the new highway and the state capital.
  • In the area Traßdorf a new connection point for the federal highway 90n is planned, which should than 14 kilometer new line connect the space Saalfeld / Rudolstadt.
  • In Ilmenau the federal highway 88 was given a new track alignment with bypass for the city and Long Meadows, which improves the connectivity of the Thuringian Slate Mountains to the motorway.
  • Geschwenda received a bypass ( B 88 ), which improves the adhesion of the area Ohrdruf on the A 71.
  • Between Zella-Mehlis and the federal highway 19 in Wernshausen the existing national road is to be incremented to the highway 62 and provided with bypasses to open up the space Schmalkalden in an easterly and westerly direction better.
  • The B 19 is extended between Meiningen and the room and bathroom Salzungen receives bypasses.
  • Between Fulda Meiningen and the main road is to be built 87n to improve the connection of the Rhön and to close the gap between the A 71 at Meiningen and the A66 at Fulda in the federal trunk road network. Due to their high costs and environmental risks, this route is controversial and a construction can not be foreseen.
  • Mellrichstadt received a ring road ( Federal Road 285 ) to help to bind the places of Streutals to the A 71.

Closing the gap with the Federal Highway 38

The northern section of the A71 between AS Sömmerda and the AD Suedharz with the A-38 will be completed in sections. The 7.7 km long section of the AS Heldrungen to provisional attachment of the federal highway 85 to the 1725 m long Schmücketunnel was passed after three years of construction on 12 December 2008 the traffic. For December 2012, the route transfer from AD Suedharz was planned to provisional attachment of the federal highway 85, the opening took place but because of a complaint against the award of the guardrail installation only on 29 April 2013.

For the rest of the route of the AS Sömmerda east to the provisional attachment of the federal highway 85 is construction law since November 2009. With the official start of this section on 23 June 2010, initially a dynamic intensive compaction of the soil was carried out ( the section performs a Erdfallgebiet with numerous underground cavities ) before the haul and Verkehrsflächenbau was taken in March 2013. The bridge was completed in August 2013. Work on the tank and Rastanlage Leubinger prince hills were in October 2012 in the preparation of the tender by the DEGES. The opening of this last section of the A 71 is expected in late 2014. In the course of the section of Heldrungen for temporary connection of the B 85, the bypass Heldrungen was built. Furthermore, it was built as a feeder for the future AS Kölleda a bypass around Dermsdorf.

Northern extension to the motorway A14

An extension to the A14 at junction Plötzkau as connecting with Erfurt, Magdeburg was considered the beginning of the design for the A71, but ultimately not included in the mandatory planning. For spatial planning securing the route corridor this extension was added in 2003 in the national development plan Saxony- Anhalt. The re-elected black - red state government of Saxony -Anhalt has decided in its coalition agreement of October 2011, to register the northern extension of the A 71 to A 14 of Sangerhausen for the next Federal Transport Infrastructure Plan. The existing federal highway 86 in 2010 showed only a moderate traffic load of about 8,000 vehicles per day on the corridor between Sangerhausen and Hettstedt, as well as the federal highway 180 between Eisleben and Aschersleben. Both highways were at least already traced out new in its southern portions between the A 38 and the space Hettstedt and provided with bypasses. However, there is still no efficient road link between Hettstedt and the A 14; here so far, only the state roads 72, 74 and 152 are available. The sharp decline in population in the Mansfeld region, traffic tends to decline. The extended A 71 would the distance between Erfurt and Magdeburg, about 30 kilometers (or 20 minutes) decrease (compared to the route via the - unfinished - Federal Highway 143). In the spring of 2013, the state of Saxony- Anhalt announced the northern extension to the federal motorway 14 for the Federal Transport Infrastructure Plan 2015 ..

Special

Wind gusts

On the viaducts Reichenbach and Tame Gera several trucks or their trailers since opening in 2003, despite existing drogues already been torn down ( in each case without charge ) by strong gusts of wind. In the sloping valleys to the north it always comes back to the emergence of strong katabatic winds from the crest of the Thuringian Forest. This was already known before the construction of the bridges, but was not considered sufficient. In stormy weather conditions is therefore limited with light emitting variable message signs on a length of three kilometers in the area of ​​viaducts Reichenbach and Tame Gera the speed to 60 km / h and overtaking for motor vehicles with a gross vehicle weight over 3.5 t displayed. In January 2007, there were two closures of the A71 in both directions - from AS Ilmenau- West to AS or AS Oberhof Gräfenroda - in connection with the Storm Kyrill, three years later, because of the storm - Xynthis a lockout over five hours. On the bridges, the subsequent construction of wind barriers with the required height for trucks static reasons not possible. For wind protection, the bridge railing on the south side of the viaduct Reichenbach by a 2.5 meter high windbreak wall with slats made of plexiglass was replaced in the summer of 2009.

Blocking

At kilometer 144, the highway crosses the viaduct Schindgraben a limestone quarry, which has been in operation since 1991. Blasting in the quarry take place every two weeks on Saturdays by 15 clock. During the demolition of the highway police car for about 20 to 30 minutes is blocked by the stone flight risk. Since the explosions are loud zoning decision still permitted from 1999, a line shift due to conservation issues as well as cost reasons was not possible and extend the reserves remain for 50 years, the DEGES tried - so far unsuccessfully - to buy the quarry.

Monitoring

According to the sixth annual report of the Thuringian State Authority for Data Protection are located in the tunnels crossing the ridge and around 280 swiveling cameras without zoom function, serve to monitor the flow of traffic and industrial installations. In addition, there are approximately 250 inductive counting stations for the collection of traffic movement and control of traffic flows. According to the report, neither of the cameras still of the counting stations, personal data are collected.

Buildings in the Thuringian Forest

In the area of ​​forest highway many large engineering structures follow each other, the most notable are listed in the following table.

Records

  • Viaduct Wilde Gera: 252 m span the largest reinforced concrete arch bridge in Germany, which is a road
  • Rennsteig Tunnel: with 7916 m of the longest road tunnel in Germany and after the Gran Sasso tunnel, the Plabutschtunnel and the Seelisbergtunnel the fourth longest two -tube road tunnel in Europe

Animal Crossing Protection

A wild exchange is prevented by bilateral, continuous wildlife fencing on the route between the Wipfratalbrücke and the triangle Werntal. In newly released sections describe the establishment of the Wildlife fence is usually done only after all construction work.

In order to enable a safe game change, ( at km 98) and Ilmenau -Ost and Meiningen North and Meiningen -South ( at kilometer 149 ) and north of Muennerstadt in Germany still rare overpasses, also green bridges were called between junctions Arnstadt -South built. Otherwise, a game trail through the countless field and forest road underpasses of A 71 can take place.

Drinking water protection

South of Muennerstadt crosses the highway for a distance of more than ten kilometers of a water protection zone that serves the drinking water for the cities Muennerstadt and Bad Kissingen. Therefore, there has been sealed by installing an additional ten centimeters thick bituminous sub-base the roadway. Also, were built against the agreement of vehicles from the road instead of guard rails in both the median strip and at the roadside concrete barriers in this section. These provide the same for the derivation of surface water from the road into the drainage system. However, only every 200 m ascent aids are available, so that after an accident the recommendation to leave the vehicle and to go behind the possibly existing guardrail, in the worst case only after 100 meters running at the roadside sequence can be done.
