The extension of tram line 8 requires reconstruction of the Gärtnerstrasse bridge across the field. A competition was held for the new bridge which was awarded to Implenia Ltd. as total contractor with the project "Primavera".

The new bridge is adapted to the environment: it has a sloped embankment on the Kleinhüningen side and a vertical wall made of natural stones. The abutment on the Kleinhüninger side is finely formed with a slanted finish made of concrete, while the abutment on the Klybecker will be made of a massive, vertical wall made from the same natural stone as the wall on the river bank.
