Foot and Cycle Bridge over the River Kinzig

The town of Offenburg is located between Karlsruhe and Freiburg, at the mouth of the Kinzig River valley and at the foot of the Black Forest. This new footbridge over the Kinzig River will create an important east-west connection for bicycle and pedestrian traffic in Offenburg.

The bridge design was given 1st prize in a restricted design competition in 2023

The bridge design is characterized by a simple and pleasantly reserved elegance with an appropriate and conscientious execution of details and maximum functionality as well as economy.

We propose a three-span bridge with a tapered floor plan on two pier bulkheads. Two edge girders in the form of hollow boxes with a high point in the middle of the bridge allow for a protected and easily accessible line route 3.6 meters wide, in which utilities can carried. The variable outer flanks of the hollow box profiles are continued in the inclination of the railings. The railing posts at the ends of the bridge are at right angles and incline towards the middle of the bridge by up to 72° with a clear bridge width of at least 3.5 metres. The tapering in the floor plan, the high point in the middle of the bridge and the slanting of the bridge flanks and railings create an elegant dynamic that gives the building a restrained but pleasant lightness.

We propose the superstructure as a hollow box with orthotropic plate and railing posts as a bright, white-coated steel construction, with the insides of the railing posts being contrasted in gold. The underside of the bridge is also set off in the same colour. A tensioned stainless steel mesh is provided as filling between the railing posts.

Narrow LED profiles are integrated between the inclined double railing posts to illuminate the bridge deck.

Completion of the bridge is anticipated in 2025.
