Railroads, routes and bridges

We construct and repair all traffic routes

We have a long experience of road, street, railway, traffic route and bridge construction. We construct new projects and repair existing works. We implement the projects flexibly according to the customers’ needs either as overall contracts, design and build contracts, alliance projects or public-private partnerships. We support the development of cities and allow the movement of people and goods between cities according to the principles of sustainable development. Well-functioning infrastructure is a profitable investment.


Our services cover everything that is needed for the construction of roads, streets, harbours and bridges – from foundation reinforcement, excavation and tunnels to municipal engineering, landscaping and maintenance. We also implement noise barriers by roads and railways as well as different kinds of earthworks and foundation engineering.

Varikkotie, Helsinki

The high-speed Jokeri Light Rail line between Itäkeskus in Helsinki and Keilaniemi in Espoo is progressing on schedule. It is the most significant construction site of the eastern section of Jokeri Light Rail and it requires a wide range of infrastructure construction competencies, from stabilisation work to the restoration of a brown trout stream.

Länsimetro

We have built Länsimetro tunnels and stations in a number of projects with the aim to streamline traffic between Helsinki and Espoo and to help the cities reduce their greenhouse gas emissions.

Jokeri Light Rail

The development stage of Jokeri Light Rail involved the design and implementation of a light railway and a depot. The project is based on a so-called alliance model and is carried out together with the other parties in the alliance.

Tampere light rail

The light rail line will be implemented using an alliance model, with the City of Tampere and Tampereen Raitiotie Oy as the customers and NRC Group Finland Oy, YIT Finland Ltd and Pöyry Finland Oy as the service providers. We are involved in both the development and implementation phase.

Tampere Rantaväylä tunnel

The longest highway tunnel in Finland improves the flow and safety of traffic as well as contributes to the development of Tampere city centre.

Auroransilta bridge construction

Auroransilta is a bridge for non-motorised traffic, facilitating the access and increasing the safety of cyclists, pedestrians, and cross-country skiers in Helsinki.

Kalajoki railway bridge in Finland

We demolished the old Kalajoki railway bridges and replaced them with new tensioned, continuous beam concrete-structure bridges, the superstructures of which were joined with a second stage concrete lane in 2017 so that they form a single bridge. The contract forms part of the Seinäjoki–Oulu railway project.

Lagedi multilevel junction

The Tallinn bypass flyover and the widened lanes will increase safety and guarantee a better flow of traffic for decades.
