The motorway tunnel (635 m) excavated under the railway interchange of Kinkempois extends in an open trench (480 m) along the canal of the Ourthe.
Many side works were necessary, including a tunnel foncé for the access to the building site, railbridge deck placed with ripage, complex blindages and reinforcement of existing civil works, all of them allowing to respect close terms and to reduce the incidence on the railway business during the crossing of the 10 railtracks.
