In Hosingen, the bypass is more than just a 4.4-kilometre road. The announced timetable distinguishes between an initial opening in 2028 and completion of the full route, expected in 2030. Work to redevelop the existing road through the village is due to begin when progress on the bypass allows traffic to be diverted onto it: building the new road and transforming the village are linked, but separate, stages.
Work began in June 2023 as part of efforts to improve safety on the N7 between Fridhaff and Weiswampach. For residents of Parc Hosingen, the stated aim is to remove some traffic from the centre and improve quality of life. These are project objectives, not yet measured results.
First section ahead of the full route
In its report on 12 November, RTL says that the first 2.4 kilometres are due to open in 2028. They include a 325-metre tunnel made up of two tubes, each designed to accommodate two traffic lanes. This initial opening therefore does not mark completion of the entire bypass.
The Ponts et Chaussées project sheet describes a route of around 4.4 kilometres, starting at the “Op der Héi” roundabout and continuing north, beyond the new Hosingen-Nord interchange, as far as Dorscheid. It lies entirely within the municipality of Parc Hosingen. RTL, for its part, reports that the route will be fully completed in 2030, as far as Dueschterhäischen.
The two deadlines do not quite match the official project sheet, which gives 2029 as the end of the works. The 2030 date is the one reported by RTL; the administrative sheet still gives 2029. This is a discrepancy between published timetables, with no information available here to establish its cause or how it may change.
A road with different configurations
The twin-tube tunnel, with two lanes in each direction, is a specific part of the route, but it does not describe the whole road. The project sheet mainly provides for sections described as “2+1”: two lanes in one direction and one in the other, then alternating, with a central reservation. It also mentions sections with one lane in each direction and others with two lanes in each direction.
The bypass will therefore connect to sections with different configurations, rather than forming a uniform carriageway with two lanes in each direction. It is part of a wider project to improve safety on the N7, but its 4.4 kilometres do not represent the full length of this road between Fridhaff and Weiswampach.
The route requires several structures: a tunnel, overpasses, structures associated with biotopes and a wildlife crossing. These crossings allow the road to pass through while maintaining other connections along its route.
Reducing disruption: measures planned
According to RTL, around 17,000 vehicles use the N7 every day. This figure describes traffic on the road; it does not mean that all these vehicles pass through Hosingen, or that they will all use the bypass. The diversion is intended to keep some traffic out of the centre, although the documents consulted do not give a quantified forecast for a reduction in traffic in the village.
The Ponts et Chaussées project sheet lists several practical measures. Four retention basins are planned for rainwater, together with pipes and discharge structures. Excavated material is not to be removed from the site: it will be reused in the project, while the stripped topsoil will be used, among other things, to cover embankments and other infrastructure.
Wildlife crossings and structures associated with biotopes are also planned. The project sheet lists several three-metre-high sound-absorbing screens. These details describe construction and design provisions. On their own, they are not enough to establish their future effects on biodiversity, noise or the comfort of local residents.
The official project sheet gives the cost as 154.35 million euros; RTL puts it at around 154 million. These figures are the announced cost of the project, not expenditure already incurred or a verified final cost.
The village: the second part of the project
The bypass and the existing road through Hosingen make up the two parts of the project. The phasing published by Ponts et Chaussées provides for the new road to be built first. Redevelopment of the old N7 through the village is due to take place once most of the bypass works have been completed and traffic can use it.
This sequence matters: a new road can offer an alternative route, but calming traffic through the village also depends on the planned work on the existing road. The project sheet refers to optimising active-mobility infrastructure and renewing networks, but does not detail a cycle path already built or a new traffic plan. The transformation of the village therefore remains a future stage, dependent on progress with the bypass.
For road users, the 2028 announcement is for a partial opening. It does not yet provide a diversion route that can be used today, or a date for the redevelopment of the road through the village. The next milestones will be the opening of this first section and the start of the redevelopment of the road through the village: two changes to follow separately.
