Liege E25-E40/A602 motorway link

When the E25-E40 link was brought into service in June 2000, the Amsterdam-Milan motorway axis was fully completed. This last 12.5-kilometre "missing link" connects the motorways to the north and west of Liège (E40/A3, E42/A15, E313/A13) to the Liège-Luxembourg motorway (E25/A26), thus reducing congestion on the Quai de la Dérivation in the centre of Liège.

It took six years to build the last section of the link which is 3.8 km long and comprises several highway structures :

  • The Guillemins interchange and Observatoire bridge
  • The tunnel under Cointe hill (the longest in Wallonia)
  • The Pays de Liège bridge, a cable-stayed bridge over the Meuse
  • The Kinkempois quadrilateral and the covered part of the Ourthe canal
  • The Grosses-Battes tunnel and interchange

Key figures
70,000 - 90,000
Traffic on the E25-E40 link now ranges from 70,000 to 90,000 vehicles per day
77,000
There is an average of 77,000 vehicles per day
82,000
On about 185 days of operation per year, traffic in the Cointe tunnel exceeds 82,000 vehicles per day
90,000
On about 26 days, traffic exceeds 90,000 vehicles per day

Continuous improvement of safety

The E25-E40 link is closed every three months for four nights running to carry out maintenance work. Emergency services take advantage of this closure to carry out various exercises.

As the E25-E40 link includes two tunnels exceeding 500 metres in length, located on the Trans-European Transport network, a European directive on the safety of tunnels obliges SOFICO to fulfil certain safety requirements. Therefore, traffic on the link is monitored at the Centre Tilleuls, alongside the link, where operators are present 24 hours a day.

There are 130 cameras along the link, fitted with automatic incident detection systems (AID). This technology can detect anomalies like a stationary vehicle, a slowdown, a pedestrian, the appearance of smoke, etc. A signal is sent to the operator who must check and confirm the validity of the alert. The operator then implements an appropriate scenario.

When the E25-E40 link was brought into service in June 2000, the Amsterdam-Milan motorway axis was fully completed.
