The Vuosaari tunnel will be closed at the beginning of next year for extensive renovations, with traffic diverted to the official substitute route.  Multiple sections of the substitute route have been upgraded over the past year, and the currently tested substitute route is ready for diverted tunnel traffic next year. How did traffic flow during the test week, and what consideration are there for next year's traffic?  Learn more in the following article.

The official alternative route for the Vuosaari road tunnel was tested between 16 and 18 June.

The improvements of the alternative route of the road tunnel leading to Vuosaari Harbour continue according to plan. Following the winter break, the work will continue on week 8 when gabion baskets are installed in the junction of Itäväylä and Kallvikintie.

The alternative route for Vuosaari road tunnel on the section Itäväylä–Kallvikintie–Niinisaarentie–Vuosaari Harbour will be improved during late 2024 and spring 2025. Roadworks on the alternative route begin on Monday, 14 October 2024.  By improving the route, we are preparing for the extensive renovation of the Vuosaari tunnel’s technical features, which begins next year and will last for nearly one year, during which time the alternative route of the tunnel will serve as a detour.

The schedule and method of implementation for the renewal of technical systems in the Vuosaari road tunnel have been established: work in the tunnel will begin with the dismantling of old systems in spring 2025.
