The City of Lahr hosted the Landesgardenschau or Garden Expo in 2018. In anticipation of this, a number of projects are developed to create greater integration of the existing city parks and to facilitate pedestrian access during the Expo.

The need for a pedestrian and cycle bridge was identified to connect the Mauerfeldpark with the Stegmattenpark over a separating adjacent motorway. The bridge geometry is complex in that the bridge must maintain clearance over the motorway and yet arrive under an adjacent bridge – and be constructed with minimal interruption to the traffic. The HRA solution for a pylon supported solution found favour with the competition jury in 2014. The project was built in time for the Landesgartenschau in 2018.

The completed project has since been awarded:

Commendation: Ingenieurbaupreis des Deutschen Stahlbaues 2019,

Commendation: Baukultur Baden-Württemberg 2020,

Commendation: "Beispielhaftes Bauen im Ortenaukreis"
