The bridge deck was designed to be as open as possible and the arched shape was chosen to emphasise the dynamic nature of the crossing experience.
The Logomo bridge is a covered pedestrian bridge that crosses the railway yard area from the junction of Ratapihankatu and Ajurinkatu to Logomo. At the ends of the bridge, there are stairway connections from the ground level to the bridge level and accessible lift connections.
The bridge design was the subject of an engineering competition in 2016, which Arco won in a team with VR Track and Lighting Design Collective with its competition entry ‘Jousi’ (‘Spring’). The basic design, alignment and architectural expression are in line with the competition entry.
The architecture and structural solution of the bridge form a whole, where structural elements and functions support each other. The lightweight glass façade, the railway-like underside of the bridge when viewed from the street level, and the curved main carrier beam with its supporting towers, which emphasises the dynamic nature of the crossing, are all both structural and architectural choices. The curvature of the bridge makes the crossing experience an interesting, and the transparent façade and the end walls offer vast views of Logomo and the urban environment.
A piece of light art, integrated into the architecture of the bridge, is an integral part of the whole. The work consists of LED matrix fields attached to the underside of the main carrier beam of the bridge. The lower surfaces of the main carrier beam, sloping towards the street level, form the backdrop for the light art. The light fields form a living surface that emphasises the rhythm of the bridge structure and reacts to the movements of people walking on the bridge in a computer-controlled way. When the bridge is crowded, for example during Logomo events, the event is reflected in the cityscape through the lighting on the bridge. The basic look of the light art is calm and the content can be changed if necessary according to events or future needs.
