“It is a very old file, a file more than 30 years old, that we got out of the stalemate. In less than a year, we managed to agree on a memorandum of understanding. Proof that the political will made it possible to succeed. Even if it will of course take time before the work ”, hoped for in 2027, begins David Margueritte, president of the Agglo Cotentin.

€ 63.3 million

This is at least the budget that will be necessary to achieve this South-West bypass of Cherbourg-en-Cotentin as estimated in 2020. But the amount could climb to € 80 million. The Manche department will cover 40% (ie 25.3 million minimum), the Normandy Region and Agglo Cotentin will cover 30% each (ie at least 19 million € each).

More safety, less pollution

“The Cherbourg-en-Cotentin station area experiences extremely high traffic peaks: 35,000 to 50,000 vehicles per day. However, we consider that a road is saturated with 20,000 vehicles per day ”, figure Jean Morin, President of the Manche Departmental Council.

“The purpose of this bypass is to make traffic more fluid and also to reduce CO2 emissions,” he underlines. Another objective: “We must improve traffic conditions and offer a relatively safe journey”, unlike the routes currently used by default by users. Starting with La Longue Chasse, which sees more than 8,000 vehicles pass per day, although it is not at all adapted to this.

Since the last consultation phase dating from 2012 according to studies from 2009-2010, “a certain number of factors have evolved, in particular the environmental factor which is at the heart of our concerns”, assures Jean Morin.

Support development

From his arrival at the head of Cotentin, David Margueritte had affirmed his desire to relaunch this project. Marc Lefèvre (predecessor of Jean Morin) followed him, as did Hervé Morin for the Normandy Region when it is not in his obligations. The mayor of Cherbourg-en-Cotentin, Benoît Arrived also : “This is a strategic project for the future” which will be integrated “with other development projects” in this territory, the Cotentin, where “we have the chance to experience magnificent development. “This is the reason why,” it makes sense for the region to participate, “explains Hervé Morin. The bypass will in particular connect the RN13 to the Fourches and Bénécère business areas as well as to the university campus which will be upgraded by Ifsi by 2024.

€ 4.25 million

The City of Cherbourg-en-Cotentin will invest on its side 4.25 million € HT to build the Thivet bar which could link the RD409 (also called avenue du Thivet which serves the Agora, the polyclinic, the area of activities of the Fourches and the university campus) to the RD64 which itself links Octeville to the crossroads of Les Pelles.

Like Jean Morin and David Margueritte, the mayor of Cherbourg-en-Cotentin underlines that the flow of traffic will “improve the quality of the air” since moving vehicles pollute less than idling vehicles which concentrate hourly. point at the road junction that is the crossroads of Cherbourg station.

Facilitate the rapid response of emergency services

Finally, the bypass will respond to “a public health question” more broadly by facilitating the flow of relief. A future new emergency center of the Departmental Fire and Rescue Service must also emerge from the ground in the area of ​​Avenue du Thivet.

Long consultation

But elected officials assure it, all this will not happen without a long process of consultation with all residents, residents and professionals (mainly farmers), as well as associations favorable (starting with the Arsoc) or not.

“Before the Declaration of Public Utility, nothing is set in stone. Before that, everything is open. It is a project which must be done in listening, in serenity ”, underlines Axel Fortin-Larivière, new departmental advisor and vice-president in charge of travel. The steering committee will meet for the first time in December.
