Ce vendredi 15 d\u00e9cembre 2017 \u00e0 12h00, a r\u00e9ouvert d\u00e9finitivement le tunnel du Chambon \u00e0 la circulation.<\/strong><\/span><\/p>\n

Apr\u00e8s deux ann\u00e9es et demie de travaux intenses, le nouveau tunnel est d\u00e9sormais compl\u00e8tement \u00e9quip\u00e9 et va permettre une pleine circulation des vacanciers, professionnels et locaux \u00e0 une semaine du grand d\u00e9marrage de la saison.<\/strong><\/span><\/p>\n

C\u2019\u00e9tait un immense d\u00e9fi d\u00e9sormais r\u00e9ussi, dans le respect du calendrier annonc\u00e9 par le D\u00e9partement.<\/span><\/p>\n

Un d\u00e9fi r\u00e9ussi : la r\u00e9ouverture d\u00e9finitive en 32 mois<\/strong><\/span><\/p>\n

En avril 2015, le tunnel du Chambon \u00e9tait ferm\u00e9 \u00e0 la circulation. 2 ans et demi plus tard, il r\u00e9ouvre \u00e0 la circulation conform\u00e9ment au calendrier pr\u00e9visionnel, avec une semaine de marge avant les vacances de No\u00ebl.
\nDepuis d\u00e9cembre dernier de nombreux \u00e9quipements suppl\u00e9mentaires ont \u00e9t\u00e9 r\u00e9alis\u00e9s dans le tunnel :
\n– \u00e9tanch\u00e9it\u00e9 et rev\u00eatements partiels du tunnel de d\u00e9rivation
\n– assainissement
\n– r\u00e9seaux \u00e9nergie et fibre optique desservant les \u00e9quipements
\n– chauss\u00e9es et trottoirs
\n– r\u00e9seau de d\u00e9fense incendie
\n– 6 niches de s\u00e9curit\u00e9
\n– \u00e9quipements de s\u00e9curit\u00e9 et d\u2019exploitation du tunnel et de la galerie de secours (local technique, automates et outil de supervision des \u00e9quipements, \u00e9clairage, r\u00e9seau d\u2019appel d\u2019urgence, dispositifs de fermeture pilotable \u00e0 distance \u00e0 chaque t\u00eate par barri\u00e8res et feux, videosurveillance, radio-transmission du r\u00e9seau de communication des services de secours dans le tunnel)
\nCes travaux ont \u00e9t\u00e9 men\u00e9s pendant les p\u00e9riodes de fermeture temporaire du tunnel, en saisons basses (printemps et automne 2017) durant lesquelles la route de secours a pris le relais pour la circulation.
\nEn 2016, le tunnel de d\u00e9rivation d\u2019une longueur de 500m, venant se connecter \u00e0 la galerie conserv\u00e9e de 500m de l\u2019ancien tunnel, avait \u00e9t\u00e9 perc\u00e9.
\nCette op\u00e9ration d\u2019un montant de 24,4 millions d\u2019euros \u00e9tait aussi un d\u00e9fi financier et politique, r\u00e9ussi gr\u00e2ce \u00e0 la mobilisation des fonds du D\u00e9partement (45%), de l\u2019Etat (25%) et des deux R\u00e9gions Auvergne Rh\u00f4ne Alpes et PACA (15% chacune), auquel viennent s\u2019ajouter les 8 millions d\u2019euros de la route de secours.<\/span><\/p>\n

Conditions de circulation dans le tunnel<\/strong>
\n>Vitesse de circulation limit\u00e9e \u00e0 70km\/h.
\n>Circulation autoris\u00e9e pour les voitures, campings car, cars et PL de moins de 26t (r\u00e9glementation de la RD1091)
\n>Circulation possible pour les cycles dans le tunnel
\n>Circulation interdite aux transports de mati\u00e8res dangereuses sauf desserte locale
\n>Circulation interdite aux PL de plus de 26t ne transportant pas de mati\u00e8re dangereuse sauf desserte locale
\nTous les panneaux de circulation routiers et autoroutiers indiquent explicitement la r\u00e9ouverture du tunnel<\/span><\/p><\/blockquote>\n


\nL\u2019\u00e9conomie locale sauv\u00e9e par l\u2019intervention du D\u00e9partement<\/strong>
\nLes saisons touristiques ont pu \u00eatre sauv\u00e9es gr\u00e2ce \u00e0 la construction de la route de secours, qui avec le passage de 900 000 v\u00e9hicules depuis sa cr\u00e9ation a permis de restaurer la liaison.<\/span><\/p>\n

La r\u00e9ouverture temporaire du tunnel en d\u00e9cembre dernier puis durant l\u2019\u00e9t\u00e9 ont permis de relancer pleinement l\u2019activit\u00e9 touristique, ce qui a \u00e9t\u00e9 salu\u00e9 par les acteurs professionnels des Hautes-Alpes et de l\u2019Is\u00e8re. Sur ces deux p\u00e9riodes, ce sont 360 000 v\u00e9hicules qui ont transit\u00e9 par le tunnel.
\nLa r\u00e9ouverture d\u00e9finitive du tunnel redonne d\u00e9sormais des perspectives de d\u00e9veloppement durable aux territoires.
\n\u00ab Nous sortons la t\u00eate haute d\u2019une p\u00e9riode longue de deux ans durant laquelle nous avons travers\u00e9 des \u00e9preuves et r\u00e9ussi. Nous nous y \u00e9tions engag\u00e9s, nous l\u2019avons fait. Le tunnel du Chambon, c\u2019est l\u2019illustration d\u2019une m\u00e9thode propre \u00e0 notre majorit\u00e9 au D\u00e9partement : nous savons agir vite, avec pragmatisme et sans pr\u00e9cipitation, pour faire face \u00e0 l\u2019urgence \u00bb affirme Jean-Pierre Barbier, Pr\u00e9sident du D\u00e9partement de l\u2019Is\u00e8re.<\/span><\/p>\n

\u00ab C\u2019est un exploit technique d\u2019\u00eatre arriv\u00e9 \u00e0 percer ce type de tunnel dans ce d\u00e9lai contraint et avec un degr\u00e9 de technicit\u00e9 aussi fort. Nous pouvons \u00eatre fiers de ce que nous avons r\u00e9alis\u00e9, c\u2019\u00e9tait un grand chantier pour un tr\u00e8s grand ouvrage. Bravo \u00e0 tous les ouvriers et tous les agents qui y ont travaill\u00e9 \u00bb. assure Bernard Perazio, vice-pr\u00e9sident du D\u00e9partement en charge de la voirie.<\/span><\/p>\n

Que va devenir la route de secours ?<\/strong>
\nLa route de secours, d\u2019une longueur de 5 kms pourrait devenir en saison, entre mai et septembre, une voie d\u00e9di\u00e9e aux cyclistes qui souhaiteraient utiliser un parcours panoramique.
\nCette route pourrait aussi servir d\u2019itin\u00e9raire de d\u00e9lestage de la RD1091 en cas d\u2019\u00e9v\u00e9nement ou de chantiers.
\nUn travail partenarial est \u00e0 mener avec les acteurs locaux, l\u2019Etat et les propri\u00e9taires pour en finaliser l\u2019usage futur, le D\u00e9partement ayant la volont\u00e9 de valoriser cette route.<\/span><\/p><\/blockquote>\n","protected":false},"excerpt":{"rendered":"
