As well as connecting the eastern and western sides of Tallinn, the intersection carries traffic between the city centre and the capital’s international airport.
For years the junction has been a bottleneck in this rapidly developing nation but thanks to EU funding it is about to benefit from a major overhaul.
A €80m project will finance the construction of 7.5km of road, new viaducts, signage and lighting, a passageway for non-motorized users, gas and electrical lines, and three new tunnels.
The provision of fire detection in these tunnels was a top priority, but regular point detection can be problematic due to false alarms and difficult maintenance planning.
Signaline FT cable was an ideal alternative with its simple installation and low ongoing maintenance – features which were regarded as vital to the success of the project.
Contractors were also impressed with the fast reaction of Signaline FT and the ease of integration with the tunnel’s complex control systems. The junction is due to be completed by mid-2013.
