Ülemiste traffic junction


Description of work



Time of completion

Civil engineering
Concrete works

In the Estonian context, the Ülemiste junction is a large-scale and complex infrastructure – the most massive intersection solution, preparing the ground for the Ülemiste district developing into the most important transport hub in Tallinn and Estonia. Structurally, the most challenging part of the junction was a 680 metre road tunnel which runs underground for 320 metres. To construct the tunnel, works were constantly carried out in a zone with a high level of surface water, the lowest point being 16 metres below the surface of Ülemiste Lake. Another important structure included in the Ülemiste junction is a 150 metre overpass. The overpass is built on boxed girders with varying heights, made of reinforced and post-tensioned concrete.

The reconstruction of the Ülemiste traffic junction won the grand prize Concrete Building of the Year 2013 awarded by the Estonian Concrete Association. Merko Ehitus Eesti project director Tiit Joosti also won the Builder of the Year title for 2013.
