It is part of the A 98 between Luckepass and Homburg Forest and crosses the river Wiese, the federal highway 317, the Grütt Landscape Park and the Wiesental railroad from north to south.

In October 1970, the Federal Ministry of Transport decided on the general alignment of the High Rhine highway, and in the same month the planning approval decision was issued for the construction section between Lucke and Waidhof.

[2] In the subsequent planning process, it was determined that the cost savings from the earthworks in the cuttings in Rötteln and Homburg Forest were not significant.

A one-way expansion would have significantly impaired the ongoing traffic, so that the decision was made to fully expand the Wiesental Bridge, contrary to the original plans.

[2] During the foundation work near the Haagen commercial canal, two stone cannonballs were found in 1978, which were attributed to a presumed enemy defence of the rulers of Rötteln Castle.

During the construction phase, increased safety requirements had to be met, as the bridge crosses a 300-hectare water protection area[8] and the city of Lörrach has extensive infrastructure for the municipal groundwater supply in Grüttpark.

[2] For this purpose, the bridge was designed in such a way that the surface water is drained away without damage using longitudinal pipes in the box girder of the superstructure.

The embankments, including the drainage troughs, were sealed with strong plastic sheeting in the entire roadway area.

The area of the Wiesental bridge was additionally secured with a 1.5 meter thick sealing layer to prevent any disruption to the water supply in the event of a serious accident.

The bridge and civil engineering department of the Freiburg Regional Council was responsible for the technical supervision and the tender design.

In addition to Bilfinger and Berger, the Wiesentalbrücke consortium included Gustav Strumpf from Rheinfelden and Locher & Cie from Switzerland.

[9] After laying the bridge piers, the consortium concreted the first span of the box girder in October 1980 and was able to complete the superstructure by July 1982.

[13] Since 2005, the Federal Highway Research Institute has been systematically recording traffic volumes at the southwest portal of the Wiesental Bridge using an automatic counting station.

[2] To ensure that traffic can easily negotiate these ascending and descending curves, the transverse inclination of the bridge varies between 4 and 6%.

The access and exit ramps to the B 317 federal highway are located in the north-western part of the bridge, which passes underneath between piers 3 and 4.

Due to slope debris and irregular subsoil conditions, pillar pair 26 was constructed as a pile foundation.

In the area of the south-eastern abutment, which is located on the slope, the support of the superstructures is offset by one bay due to the inclination of the terrain.

It consists of two prestressed concrete superstructures and 59 bridge spans, each with a box girder cross-section, and is founded on 57 pillars.

The bridge superstructure was divided in order to achieve smaller displacement paths for the individual transition structures.

In the case of pillar pairs 3 to 4, for which no approval has been given, the potential danger for this work is too high due to the adjacent federal highway 3.

[25] Since its inception, the Bridge Gallery on the Wiesentalbrücke in Lörrach has become a popular hot spot for the graffiti scene from all over Europe.

Since 2005, an automatic counting station of the Federal Highway Research Institute (BASt) at the south-western portal of the Wiesental Bridge has been recording the traffic volume.

At the southern entrance to the Lörrach district of Brombach, a 26-metre-high vertical concrete production plant was built in the early 1980s in the immediate vicinity of the bridge construction site.

Before construction work began on the Wiesental Bridge, it had to be ensured that a landslide that occurred in August 1979 would not affect the route of the A 98 motorway running downhill in the area of the Röttelnweiler hamlet (Röttler Hang) in the long term.

The geologically unfavorable conditions at this point consist of oligocene clay and mudstone layers, sand and sandstone deposits as well as a 350-meter-long and 150-meter-wide fossil landslide[34] The slipped soil made it necessary to excavate a cut, and since the sliding friction in this area was too low, additional safety measures had to be implemented.

In order to slow down the movement of the slope, a ballast was placed in the cut area and a concrete pile slab and a deep drainage slot system were installed to improve water permeability.

[35] Following these measures, the embankment on the mountain side was secured in terraces with anchored wall elements made of reinforced concrete.

The signs are located at highway kilometers 6.2 and 9.5 of the A 98 and show not only the castle and the Wiesental valley but also the hills and mountains of the Black Forest.

In 1988, Bauhaus student Arthur Schmidt painted a picture in the style of expressive realism entitled "Landscape Conservation Area".

[39] In the early 1980s, the visual artist Waltraud Hett thematized the Wiesental Bridge in a painting called "Highway construction near Rötteln".
