Teollisuuskatu is a street situated in a valley, with two bridges as main crossing points. In the current situation, the axis is a barrier in the landscape, with weak or few connections between the surrounding city districts and urban spaces. One of the main goals for the masterplan is to strengthen the connectivity between the bordering areas, with new, safe
and liveable, bike and pedestrian routes and crossing points along the axis. The old bridges with their valuable structures remain, as they are important viewpoints and cultural heritage in the axis landscape. They allow for very distinctive views opening along the axis and adds a historical layer in the surrounding.
The landscape of the wide street is made more interesting and characteristic with rhythmically situated green pockets, parks, and vegetation as interruptions in the dense city structure and the vast road landscape. The overall blue-green infrastructure of the axis is improved and developed through a strategy of permeable surface materials, adding biofiltration where
possible and creating new visible solutions for gathering storm- and rainwater. The strategy is also used in the Töysänkatu and Kuortaneenkatu sidestreets, made possible by the new traffic arrangements. The concept for the new vegetation in the area originates from the history of the axis as a railyard, promoting ruderal vegetation, single trees, and larger tree groups.
The axis of Teollisuuskatu already contains very diverse and actively used spaces, such as the park Dallapénpuisto. The enjoyable and pleasant park for staying and organizing events creates a place of human scale in the otherwise large-scale environment.
But the future traffic arrangements will also affect the park, and therefore, both the development of the park as well as the creation of new city culture hot spots along the axis was examined. The Päijänteentie crossing was seen as one keyspace for a new, versatile space.
