A 170-meter-long green, noise barrier designed by LAND has been placed along a once heavily trafficked street, Lidingövägen, bordering a sports field in central Stockholm. Besides from lowering the noise effects from 60 decibels to 55, the barrier enhances biodiversity, increases absorption of particles and manages stormwater with the help of 28,000 plug plants inserted in the screen. The selected plants consist of a mix of native species and ornamental plants that also offers a rich bloom in various color themes from spring to autumn and can withstand drought and relatively nutrient-poor soils. Great woodrush, polypodies, orange hawkweed, bloody geranium, geranium ‘Rozanne’, Albanian pinks, sand pink, sea thrift, silver speedwell and blue fescue.
The barrier’s base construction consists of 30 cm thick corten steel, mesh screens alternating between being planted with the plug plants or artistically illuminated. The screens have a core of mineral wool with a layer of plant substrate on each side. In winter, when the plants are dormant and withered, it is the rust-brown panel and the lighting design that take over.
As Lidingövägen transformed from mainly dominated by car traffic to becoming an important link in the bicycle commute system with many pedestrians and bikers using the route in their everyday life, the green screen is perceived close-up by by passers. The plants and lighting provide a varied and intricate experience. The back of the screen, that faces the sports field, serves a different function and pace, here grass has been hydroseeded to form a green textured wall.
