Pour connecter la nouvelle section de tunnel \u00e0 Mitholz \u00e0 la section existante \u00e0 voie unique, des travaux de construction importants sont n\u00e9cessaires sur le tube existant. Pour cela, le tunnel devra \u00eatre ferm\u00e9 pendant huit mois. En raison de cette longue fermeture, le Parlement a charg\u00e9 le Conseil f\u00e9d\u00e9ral de r\u00e9examiner l’extension compl\u00e8te du tunnel, qui ne n\u00e9cessiterait pas de fermeture totale prolong\u00e9e. Les r\u00e9sultats seront pr\u00e9sent\u00e9s par le Conseil f\u00e9d\u00e9ral au Parlement dans le cadre du rapport interm\u00e9diaire sur l’\u00e9tape d’extension STEP 2035. Sur cette base, le Parlement devrait d\u00e9cider au d\u00e9but de 2023 s’il souhaite maintenir l’extension partielle d\u00e9j\u00e0 d\u00e9cid\u00e9e ou si le tunnel doit \u00eatre enti\u00e8rement d\u00e9velopp\u00e9. La BLS attend donc jusqu’\u00e0 ce moment-l\u00e0 pour lancer l’appel d’offres pour les travaux principaux de l’extension partielle. En revanche, elle commencera d\u00e8s 2022 certains travaux pr\u00e9paratoires n\u00e9cessaires tant pour l’extension partielle que pour l’extension compl\u00e8te.<\/p>\n
La capacit\u00e9 sur la ligne de montagne du L\u00f6tschberg est suffisante pendant la fermeture<\/strong><\/h5>\nSi le Parlement opte pour l’extension partielle, les travaux de construction devraient commencer en 2025 et durer jusqu’\u00e0 fin 2031. La fermeture de huit mois est pr\u00e9vue vers la fin de la p\u00e9riode de construction. Pendant cette fermeture, les trains de voyageurs circuleront sur la ligne de montagne. Les trains de marchandises seront d\u00e9tourn\u00e9s par la ligne de montagne ou l’axe du Gotthard. Les capacit\u00e9s du transport automobile et des trains RegioExpress \u00e0 travers le tunnel de base du L\u00f6tschberg resteront inchang\u00e9es. En cas d’extension compl\u00e8te, un changement de projet correspondant sera probablement mis \u00e0 disposition du public \u00e0 la mi-2023. Les travaux de construction dans ce cas s’\u00e9tendront de 2026 \u00e0 fin 2033.<\/p>\n
