Covered section of the Junglinster bypass

Realization of a covered section in reinforced concrete 150 meters long.

Construction of a 5.7m high/150m long covered trench on a curve, allowing passage under the N11 national road.

The East and West entrances to the OA 110 are made of prefabricated structured sections, developed and put in place by Felix Giorgetti.

Earthworks in marly soil

17-ton parts

A double winch crane was used to tilt the sections and columns over 8m high and weighing approximately 17t.

The walls at the entrances to the structure are covered with acoustic panels in order to reduce the sound effects of road traffic. The visible surfaces are water-repellent and covered with an anti-graffiti coating. The sidewalks are paved and fiber reinforced concrete slot gutters collect water and hydrocarbons. Earthworks were carried out in marly terrain.
