Ny bro og støttemur bygges

The construction project 'Talsperrenbrücke und Stützwand Bleilochtalsperre' involves the erection of a new bridge structure spanning the Bleiloch reservoir and an adjacent retaining wall along the shoreline. The bridge is designed as a semi-integral structure composed of six spans, utilizing a launching gantry positioned just above the water surface for the superstructure erection. The retaining wall runs parallel to the existing federal road B90 and is constructed as an anchored secant pile wall. After completion, the head beam of the retaining wall will be accessible to pedestrians and cyclists, complementing a new cycle path integrated into the project.

Prosjekt med 26,9 millioner CHF

The total construction volume amounts to approximately 26.9 million Swiss Francs (around 28.2 million Euros or 30.1 million USD). The scope includes specialized works such as temporary works, foundation construction, earthworks, reinforced concrete work, waterproofing, and erection of supporting scaffold structures. The retaining walls are deeply founded and anchored, built using a sequential 'Pilgerschrittverfahren' (stepwise advancement) technique while accommodating the limited space along the B90 highway. The bridge foundations and substructure were scheduled for construction between July 2023 and February 2024, timed with a lowered water level in the reservoir to facilitate works.

Bygging under vanskelige forhold

One of the main challenges faced in the project is constructing the substructures under the constrained environmental conditions posed by the reservoir while maintaining traffic flow on the existing B90. The superstructure is assembled via a launching gantry above the water level, which requires precise execution to ensure safety and structural integrity. Concurrently, the retaining wall is built on a linear construction site with tight space constraints, demanding careful planning and traffic management.

Forbedret trafikk og miljøtiltak

This project delivers significant benefits to the region by enhancing traffic safety through improved road alignment and by easing transit traffic through the village of Saaldorf. Furthermore, the infrastructure is being adapted to meet future traffic volume expectations. An important societal advantage is the creation of a new dedicated bicycle path that crosses both the retaining wall and the new bridge, promoting sustainable and active transport modes. Additionally, the project includes environmental compensation measures such as reforestation, offsetting, and land rehabilitation undertaken by the Deutsche Einheit Fernstraßenplanungs- und -bau GmbH (DEGES).

Byggestart juni 2023, avsluttes 2025

Construction began in June 2023 and is expected to complete by May 2025. The project owner is DEGES, based in Berlin, which also oversees environmental mitigation activities. Overall project planning and management are conducted by the engineering firm Leonhardt, Andrä und Partner from Stuttgart. Throughout the project timeline, necessary approvals have been secured, with works progressing according to the established schedule.
