Improving traffic connections in Espoo

In Espoo, in the Helsinki metropolitan area, in Finland, we are building the Turveradantie street, a main link connecting the districts of Leppävaara, Mankkaa and Tapiola and passing over the Turunväylä highway. Turveradantie street will connect with Turunväylä highway via the Turvesolmu graded interchange that is part of the same contract. The contract covers major earthworks and civil engineering work as well as six new bridges.

The Turvesolmu and Turveradantie project is the all-time largest individual project undertaken and self financed by the City of Espoo; it provides employment for hundreds of people. Nearly all of the work included in the contract lies within Lemminkäinen's core areas of infrastructure construction expertise. For example, the contract entails excavation, crushing, treatment of contaminated soil, piling, stabilisation and paving. We are also improving noise reduction in the area to minimise noise nuisance in residential areas.

Turveradantie significantly improves not only traffic connections within Espoo, but also connections to the main road network of the Helsinki metropolitan area. It is estimated that in 2030, approximately 9,800 cars per day will use the street between Mankkaantie and Sinimäentie. The currently unbuilt area will be developed; a shopping centre is also being planned close to Turveradantie street.

In 2014, piling and bridge casting were started at the construction site. The construction site was awarded Piling Site of the Year 2014 by the Confederation of Finnish Construction Industries RT. The grounds for the award included the project's extremely challenging foundation conditions. Paving and construction of stone-paved areas and noise barriers as well as landscaping will begin in spring 2015. The contract will be completed in late 2015.
