Skanska to build part of Lahti southern ring road in Finland


Skanska, in a consortium with Pöyry, has signed a contract with The Finnish Transport Agency for the construction of the Lahti end of the Lahti southern ring road section in Finland.

Skanska’s share in the contract will be €161m.

The Lahti end of the new ring road, which includes three interchanges, two tunnels and 12 bridges, is the technically most demanding and financially most significant section of the project.

The ring road project is aimed at ensuring smooth and safe flow of traffic on Highway 12 and promoting the development possibilities of businesses and efficient land use in the Lahti region.

Construction work has already begun. The project is scheduled to be opened for traffic in November 2020 and for completion in September 2021.

In December 2017, Finnish company Caverion entered into an agreement on technical tunnel systems with the Valtari consortium comprising Finnish Transport Agency, city of Lahti, municipality of Hollola, Skanska Infra and Pöyry Finland. The consortium is constructing the Lahti stretch on Highway 12.

The development stage of the project began in August 2017 and will last until spring 2018. Caverion will be responsible for the technical systems in tunnels – heating and sanitation; ventilation and air conditioning; cooling; electricity; information and communication services; security and safety; and telematics (traffic management).

The entire project includes the construction of Highway 12 Lahti southern ring road and improving the south access road to Lahti on Highway 167.

Construction work on Highway 167 commenced in spring 2017 and construction on Highway 12 will start in 2018.

Caverion is implementing the technical systems for the Teollisuuskatu tunnel in Helsinki and the Isokylä tunnel in Salo on Highway 1.

Earlier, Caverion had delivered technical systems for tunnels such as the Ring Road 1 Mestarintunneli in the Leppävaara district of Espoo, the Markkinamäki tunnel on E18 motorway and the Hämeenlinna tunnel on Highway 3.
