Nature of the work 

Here are some key components of the planned work: 

• Replacing the P-113 Bridge and raising the soffit;
• Milling and paving of roadway approaches;
• Replacing damaged fences and building new fences, where required, including at the top of the rock faces on the northeast side;
• Sealing of the door between the JCCBI pumping station and the gallery of the St. Lawrence Seaway Management Corporation lock, to reduce the risk of flooding;
• Improving the efficiency of the heating cable system along the approaches (ditches) and in the north fan drift;
• Replacing eight foundation blocks and completing various related work. 

Planned traffic hindrances and detours 

Traffic impacts are planned based on the needs of all users. 

Road users 

• No traffic hindrances are expected in the tunnel;
• On the west side of the tunnel, westbound traffic will be diverted to a contraflow lane on the east side (south lane). 

Pedestrians and cyclists 

• Two alternative active transportation options will be available:  
  • la fermeture complète du trottoir, accompagnée de la mise en place d’un service de navette; 
  • ou la déviation du trottoir vers le sommet de la paroi nord‑ouest, en passant par le terrain de la Voie maritime du Saint-Laurent.
