" Bundesstraße 14n " was the temporary name of the new section of Bundesstraße 14 from the Winnenden junction to Winnenden-West / Leutenbach , which was partially released on November 27, 2006 after several years of construction. The actual B 14 continued to run through Winnenden. The further section through the Leutenbacher Tunnel to Nellmersbach was released on September 21, 2009, whereupon the now completed bypass road was rededicated to the B 14. The previous B 14 through Winnenden and Hertmannsweiler was downgraded accordingly.
Funding has already been made available by the federal government for the further expansion of the B 14 to or in Waldrems. Construction was supposed to start at the beginning of 2010, but the start of construction was postponed indefinitely due to cuts in federal funding for the construction of highways. For the rest of the expansion of the section between Waldrems and Backnang, u. a. With a new route between Maubach and Heiningen through, the funds are currently lacking.
Start of planning
The first plans for the bypass around Winnenden had been in existence since 1957, and the route has been changed again and again since then. Initially, the planning was closely linked to the Neckar-Alb motorway . However, these were abandoned in 1979. Since 1979, the plans for the motor road have been referred to as the new section of Bundesstraße 14. In 1986 it was divided into a northern and a southern construction section. The traffic load in the through town was approx. 30,000 vehicles / day, the traffic load on the new B 14 will be approx. 35,000 vehicles / day predicted, 2015 approx. 40,000 vehicles / day. The current route was finally determined on June 5, 1999, the length of the construction route is approx. 5.3 km, plus branch lines of approx. 2.8 km in length. On December 27, 1996, approval was given by the Federal Ministry of Transport . The new line primarily serves to relieve traffic in the large district town of Winnenden, which hopes that the bypass road will reduce the previous through traffic to a quarter. A large part of the Winnender traffic also affected Hertmannsweiler.
Course of construction work
First section 2006
Construction of the first 1.5 km long section of the southern construction section began on July 23, 2001, and the approval was given on November 27, 2006. Around 2.0 km of secondary line were built as feeder and exit roads, including the K 1898, In the course of the first part, the erection of five structures was necessary:
-
Transfer of the B 14n via the north-west ramp of the B 14 (Winnenden-Süd junction)
(August 2003 to November 2005) - Bridge over a farm road
(December 2001 to March 2003) - Bridge over the Waiblingen – Schwäbisch Hall-Hessental railway line
(October 2003 to October 2005) -
Bridge over the Zipfelbachtal (465 m)
(August 2002 to March 2006) - Bridge of the L 1127 over the B 14n
(July 2001 to July 2003)
Second section in 2009
Construction of the second, approx. 3.8 km long section began with the preparatory work for the 1080 m long Leutenbach tunnel , which crosses under the Hungerberg. In order not to cut up the clay pit of the adjoining Pfleiderer brickworks, the tunnel was built longer than originally planned.
It was planned that the Pfleiderer company would contribute around 15 million marks (as of 2001) to the construction costs for the tunnel extension. This assumption of costs was reversed after Etex AG took over the brickworks. The brickworks were shut down in 2009 because the clay pit is exhausted or the delivery of clay is no longer profitable.
The earthworks on the route began in November 2005, construction of the tunnel began in spring 2006. The first tunnel breakthrough was celebrated on September 4, 2007, and on February 26, 2008, after eight months of construction, the second tube was ceremoniously pierced. The two ramps in the tunnel each have a gradient of approx. 4% when they exit.
North of the Hungerberg, the route runs parallel to the Murrbahn line through the Rotbachtal. A new bridge there leads a dirt road over the B 14 and the railway line. The further course of the route swings away from the railway line to the Nellmersbach junction east of the town's industrial park. North of the junction, the new line joins the existing, two-lane B 14, the further four-lane expansion of which is initially planned to Waldrems. The total length of the branch lines built is around 0.8 km. Construction of the Nellmersbach junction began in autumn 2007, and the route itself had been under construction since February 2008.
Since the beginning of May 2009, traffic in the Nellmersbach area has been routed over the newly built west route, over the ramps at the junction and the bridge. The old section of the B14 north of the former intersection was excavated and replaced about two meters deeper by the last section of the east route. This section, which was last paved, was put into operation at the beginning of August as the first section of the new line, but only on a single track.
On July 11th, 2009, a “tunnel festival” took place, with the routes serving as driveways and parking spaces for visitors. On the morning of September 21, 2009 the tunnel was inaugurated with speeches, music and a vintage car parade. Six days before the federal elections, no fewer than 13 politicians cut the black, red and gold barrier tape into 14 parts with media coverage. District Administrator Fuchs postulated a time saving of 15 minutes per passage, or 110 hours per year, as well as a saving of 15 to 20% CO 2 , several 10,000 tons per year. Farmers demonstrated next to the new road with burning bales of straw against low milk prices and shed 40,000 liters of milk. Cyclists were able to explore the tunnel and route while the final work on the barriers was being carried out. In addition, the southern section (B14n), on which the overtaking lanes had been closed since 2006, was completely closed. The actual traffic clearance did not take place until the afternoon, although after 4 p.m. the vehicles waiting in the backwater in front of Winnenden-Süd were initially allowed to drive northwards in two lanes behind police cars. Half an hour later, the barriers at Nellmersbach were removed, and traffic was also directed south in two lanes and released.
The temporary designation B 14n was replaced by B 14 , although the signs were initially set up provisionally. AS Winnenden was closed for marking work for two days. The former B 14, which had previously crossed Winnenden and Hertmannsweiler, was downgraded to Kreisstraße 1847 or state roads 1120 and 1140, respectively.
Cross-section, drainage and noise protection
The motorway-like route has a two-lane cross-section with an emergency lane for each lane. The width of a one-way carriageway is 7.5 meters, the width of the hard shoulder is 2.0 meters. For drainage of the roadways, three rain clarification basins and three rain retention basins, combined with rain clarification basins, were built along the route. According to previous reports, no noise protection is required to shield the route from the nearby residential areas of the city of Winnenden and the community of Leutenbach , especially since the railway line is in between. However, the railing of the Zipfelbachtal bridge was clad with special glass in the direction of Winnenden. A four-meter-high and 400-meter-long earth wall was also built in the area of the Nellmersbach location, or the roadway was laid correspondingly deep.
Compensation and replacement measures
After the slight relocation of the L 1127 and the creation of two roundabouts , the previous course of the road was renatured. In addition, trees were planted on embankments and in the vicinity of the route. The renaturation of rivers is also part of the compensatory measures. After the opening of the B 14 to Nellmersbach, the Winnenden through traffic was made unattractive for through traffic. This was achieved through dismantling measures and changed traffic light controls.
costs
The total costs for the project are estimated at around 101 million euros, of which 74 million euros are attributable to the eight structures that have been built. The Zipfelbachtalbrücke (structure 4) was valued at around 12 million euros. The 1,080 m long Leutenbacher Tunnel (building 6) is expected to cost 56 million euros. Of this, the shell construction accounts for around 50 million euros, and the technical equipment 6 million euros.
Traffic regulations
Since initially only the first section of the southern construction section was completed and released and the B 14 temporarily ended exactly at the gates of the community of Leutenbach, extensive traffic control measures were taken so that the traffic load in the communities of Leutenbach and Nellmersbach does not increase many times over. This included the narrowing to only one lane, a speed limit of 30 km / h in Leutenbach and the complete closure of the exit in the south direction at the Winnenden-Süd junction and the management of main traffic in the north direction on two lanes into the city of Winnenden. With the opening of the remaining section to Nellmersbach, these measures have become obsolete.
Further expansion projects
The plan approval decision was issued in 2005 for the four-lane expansion of the B14 from Nellmersbach to the motorway feeder road (L1115).
The section to Waldrems is currently being expanded to four lanes on the existing route and will be released at the end of October 2018. With additional federal funding for road construction resulting from the higher truck toll in 2009, the start of construction could be brought forward. The section to Backnang should actually be completed for the 2006 World Cup. On November 23, 2009 the clearing work between Nellmersbach and Waldrems began, the Europe-wide tender was imminent. The road construction of the 1000 m long section to Waldrems could begin in summer 2010 at the earliest, the time requirement was estimated at one year. In addition, the through traffic in Waldrems with traffic lights is to be expanded free of crossings as soon as possible. For this purpose, a semi-connection point with an overpass and a roundabout is to be created. This 900 m long extension with a 135 m long tunnel in Waldrems should take another three years. Total costs of 17 million euros can be expected. At the end of May 2010 it was announced that the expansion had been postponed until further notice due to the reduced allocation of funds from the federal government for highway construction.
A new route is planned from Waldrems to Backnang, which will run further away from Maubach, but also closer to Heiningen. Around Backnang via the Murrtal viaduct, which is currently being converted, to the connection to the L 1115 motorway feeder, the same route will be expanded. According to the Mayor of Backnang, Nopper, “this state road is indeed the busiest route in all of Baden-Württemberg”, but the costs have risen from the originally planned 8 million euros to 48 million euros, so that there are fewer opportunities for rapid implementation.
In the further course of the B 14 along the industrial area Lerchenäcker was expanded over a short distance with separate lanes. An extension of this type of expansion is possible up to the confluence with Sulzbacher Straße or Strümpfelbach.
For the relocation of the through-road from Oppenweiler from the town center to the industrial area parallel to the route of the Waiblingen – Schwäbisch Hall-Hessental railway line, a route had already been established in 1986; the project has been postponed several times as a result of German reunification, but is included as an "urgent need" 23 million euros for a 2.6 km new line in the current Federal Transport Infrastructure Plan 2003 . As part of the appointment of the new mayor Steffen Jäger, District Administrator Fuchs announced the continuation of the planning approval procedure for September 2010 at the beginning of March 2010, as well as initial discussions in spring. On the occasion of the first 100 days in office, Mayor Jäger announced that for "the project of the century" it was assured during a discussion in the regional council that the planning approval for the new B14 route would be initiated in 2011. The northern part of the bypass is to run on the dam of a flood retention basin that is currently being planned for the Murrtal water association .
In Sulzbach an der Murr , the B 14 meets the state road 1066 , which leads traffic in the Lautertal towards Löwenstein, as well as giving right of way in the further course of the Murrtal towards Gaildorf. To follow the B 14 you have to turn left in Sulzbach, because it runs uphill (“Sulzbacher Steige”) towards Schwäbisch Hall .
A bypass around Michelfeld is classified as a "further requirement". In the western suburbs of Schwäbisch Hall, the federal highway 19 comes from the south and meets the B14. On a common route through the city and the Kochertal, these run north to the A 6 junctions Schwäbisch Hall and Kupferzell. To the northwest of Schwäbisch Hall, the district road 2576 in the Hohenlohe plain parallel to the railway line to the Schwäbisch Hall junction will be expanded into a western bypass, which means that trucks can no longer travel through the city and the Kochertal. A rededication of the K 2576, which will be expanded in the future, to the B 14 / B 19 would be obvious, but has not yet been planned. In the Kochertal itself, the joint route of the B14 / B19 is to be relocated from the village of Gelbingen.
