“The Vuosaari road tunnel needs to be repaired because its safety systems and other equipment that help traffic flow are reaching the end of their life cycle. At the same time, other repairs will be carried out in the tunnel. This will keep the tunnel safe and traffic flowing smoothly in the future.”
“The Vuosaari road tunnel runs from the Ring Road III interchange on Itäväylä to Vuosaari harbour. The tunnel is about 1.5 kilometres long with two lanes in each direction.”
“All safety equipment and other tunnel technology will be replaced. This includes fire alarms, smoke extraction, ventilation and alarm systems, lighting, cameras and traffic management systems. At the same time, the tunnel structures will be repaired and the drainage and fire-extinguishing water systems under the tunnel will be replaced.”
“The construction work in the tunnel will begin on 6 January 2026, and for safety reasons, it will require the tunnel to be closed to traffic for approximately one year.”
“During 2025, the smooth functioning and safety of the detour have been improved in many places.”
