Project in the heart of Tallinn traffic

We are building the Lagedi multilevel junction on the heavily congested Tallinn bypass. Our contract includes two 104-metre bridges, a pedestrian underpass, cycling and pedestrian lanes and 3.2 kilometres of new road.

The slightly over three-kilometre bypass in Tallinn is known as a dangerous and congested road. Between 2001 and 2014, more than a hundred accidents were reported on this stretch alone. The flyover under construction and the widened lanes will increase safety and guarantee a better flow of traffic for decades.

The Lagedi contract is more challenging than a usual road construction project. Widening the road called for a solid foundation in the middle of wetlands, requiring removal of some of the turf. We worked in winter to prevent our equipment from sinking in the bog. Outside the road, we made sure to make as little contact as possible with the environment.

What makes the project especially demanding is the railway line running through the construction site, with trains passing through. At the busy interchange of road and rail traffic, installation of lighting, railway cables, communication networks and power cables takes place in extreme conditions. We scheduled our work above the railway for nighttime, making it possible to occasionally interrupt rail traffic.

The tight schedule has required an exceptional number of special permits, and a great deal of advance planning. The challenges have been met on schedule, thanks to our skilled employees.

Both sides of the flyover will be completed by the end of summer. After that, we move on to demolition of the old bridge. This will also take place at night, when rail traffic can be interrupted.

The Lagedi multilevel junction and widening of the bypass will be completed in January 2018.
