Pedestrian bridge Oslo
PEDESTRIAN .BRIDGE AND CYCLE PATH | YTRE RINGVEI. OSLO | NORWAY
In colaboration with Gaute Mo AS and Solborj Architects.
Client: Oslo Komune
The projec aims to connect a train station to a residential area located at the northeast part of Oslo with a new cycle and pedestrian path.
The pedestrian bridge crossing Ytre Ringvei is a 80 meter long continuous steel box girder structure with four spans, the longest is 22 meters long. The bridge has an asymmetric cross section shaped to optimize the structural performance and necessities. In plan view the bridge is shaped to follow the serpentine line of the adjacent paths, avoiding threes and other natural obstacles on its way through the forest. Leaning at the ends on concrete abutments cladded in local natural stones, the bridge is supported by tree slender steel columns. With a cross section depth of 0.85 meters and a maximum span of 22 meters, the depth to span ratio is only 1/26.
The structure of the bridge is of weathering steel. Weathering steel, best-known under the trademark COR-TEN steel, is a group of steel alloys which were developed to eliminate the need for painting, and form a stable rust-like appearance when exposed to the open air.
