Upgrade of E18 Turku Ring Road in the centre of Raisio enhances traffic safety and flow
Together with WSP Finland, we are delivering the upgrade project of E18 Turku Ring Road in the centre of Raisio. Traffic volumes on the route are high, with a particularly large share of heavy vehicles due to the nearby ports, oil terminal, and shipyard. The project will improve traffic flow and safety in the area while reducing traffic noise and other environmental impacts.
The project aims to improve traffic arrangements in the heart of Raisio to meet the requirements of the European TEN-T core network. At the same time, the project will improve traffic flow and safety, as well as the living environment for local residents. We are the main contractor for the project.
In the first phase of the project, which began in July 2026, we are constructing a road tunnel through the city centre, carrying out street improvements in the centre, and upgrading the E18 ring road southwest of National Road 8. We are also carrying out the utility and equipment relocations required for the commissioning of the first phase, along with other necessary works, such as constructing the connection to Petterinpellontie.
In addition, we are installing traffic lights on the street network and improving lighting along the roads, as well as constructing a total of 3.8 kilometres of noise barriers and noise barrier fences.
The project is being delivered using the alliance model. The client parties are the Finnish Transport Infrastructure Agency, the City of Raisio, and Fintraffic Road Ltd. The service provider parties are Destia (main contractor) and WSP Finland.
