Map with all coordinates: The federal highway 172n (abbreviation: B 172n ) is the southern bypass around Pirna . It has been officially under construction since August 3, 2017.
The aim of the new road is to reduce through traffic in Pirna , bypassing the steep ascent to the plateau near Pirna-Sonnenstein , as well as improving accessibility to the communities of the Elbe Sandstone Mountains along the federal highway 172 .
planning
The first plans for a bypass of the B 172 were already drawn up in the GDR times in connection with the planning of a new motorway from Dresden to Prague (today federal motorway 17). However, at that time only a bypass near the city center from the so-called Feldschlösschen intersection via Einsteinstrasse and Seminarstrasse to the so-called Hanno curve was to be implemented.
In connection with the sudden increase in traffic on the B 172 after 1990, it quickly became clear that only a bypass far away from the city center could really relieve the Pirna city center from through traffic. In the 1990s, different variants were examined, some of which provided for a bypass far to the south of the city near the districts of Rottwerndorf and Neundorf .
From the plans of the DEGES a route of concretized as a preferred variant out that the amount of the individual good Lindigt on Feist mountain from the feeder road of the B172 of Gemarkungsgrenze of Pirna and branches off approximately at the height Zehista the valley of the Seidewitz traversed passed the southern slope of the carbon mountain, in At the height of the barracks area in the southern suburbs , crosses the Gottleuba valley and through the wooded area of the Viehleite reaches the route of the "old" B 172 south of the Sonnenstein district .
This so-called "variant 1A" was confirmed in January 2006 by the Pirna City Council . A connection to the S173 Pirna-Berggießhübel in Seidewitztal is planned. For ecological reasons, however, the Gottleubatal is crossed on a high bridge in order to minimize the encroachment on the forest area of the Viehleite, so that a connection to the S174 in the Gottleubatal is not possible. The Kohlberg is now crossed with a tunnel.
On August 9, 2006 the competition for the bridge construction over the Gottleubatal was decided. A design by the engineering company Schüßler-Plan in collaboration with the Rostock architect André Keipke was selected for implementation.
After objections from the Saxon State Ministry for Economics, Labor and Transport regarding the high costs, the design planning was changed in 2012 from a partial plan-free connection to a traffic light-controlled connection to Pirna-Sonnenstein.
The planning approval decision for the project was issued in December 2015 and became final in March 2016.
After completion, the B 172 will be moved from downtown Pirna to the southern bypass.
implementation
In September 2016, the land acquisition of the land required for the construction and nature conservation compensatory measures began. The archaeological explorations began in October 2016.
In January 2017, the preparatory work on Zehistaer Straße and in Seidewitztal began.
In the summer of 2017, the actual construction work began with the bridge over the Seidewitz and Zehistaer Straße (S 173). The "first groundbreaking" took place on August 3, 2017. It is assumed that the bridge will take 21 months to build. From summer 2018, the construction of the high bridge over the Gottleubatal will take place within 34 months. From the end of 2019, the construction of the Kohlberg Tunnel will take place over a period of 27 months. The entire route is to be opened to traffic in 2022 .
Routing and structures
The southern bypass will be laid out in four lanes (two lanes with two lanes each) between the motorway feeder and the connection to Zehistaer Straße (S 173). Only one lane will be built from the junction with the S 173 to the connection with the previous B 172 south of Pirna-Sonnenstein. Due to the incline in the direction of Sonnenstein, two lanes are created in this direction of travel, but only one in the opposite direction.
The following structures are being built:
- Connection structure to the B 172 motorway slip road
- Bridge over the Seidewitz
- Connection to the S 173 Pirna-Berggießhübel
- Kohlberg tunnel (315 m length)
- High bridge over the Gottleubatal (916 m length)
- Connection structure to the B 172 old south of Pirna-Sonnenstein
costs
The cost of the Pirna southern bypass was put at around € 72 million in 2010. According to the Federal Transport Infrastructure Plan 2030, costs of around € 97 million are currently expected. It is financed by public funds from the BMVBS budget .
Commitment to the southern bypass
The citizens' initiative B172a was founded in 2011 with the aim of completing the southern bypass as quickly as possible. Members include politicians and representatives of the regional economy. The Society for the Promotion of Environmentally Friendly Road and Transport Planning (GSV), a road construction lobby association, has supported the citizens' initiative for many years. Der Spiegel wrote that the GSV itself has already set up the citizens' initiative for road construction.
