Digitalisation continues to reshape maritime operations, and the need for reliable, standardised and trusted information exchange is growing fast. One of the goals of the NELSON project is to enable interoperable maritime services that support safer navigation, more efficient traffic management and future-ready operations. S-100 services and Maritime Connectivity Platform (MCP) are key enablers in this context.

NELSON is a €15 million EU co-funded project that brought together 10 partners from Finland, Sweden and Spain. The project has had a somewhat eventful beginning: since September 2025, 14 milestones have been completed, and numerous events and info sessions have been held to inform and involve project stakeholders.

The extensive renovation of the Vuosaari tunnel began three weeks ago, on 6 January. Take a look at the progress of the tunnel renovation and traffic flow on the detour and read about the new traffic arrangements on Ring Road III during construction.

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.

Fintraffic studied the value of the traffic data economy with consultancy firm FLOU in December 2024. According to the study, the value of the traffic data economy in Finland has increased to EUR 500 million, more than EUR 50 million of which is produced by Fintraffic alone (+35% since 2022).

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.

In today’s data-driven world, enterprises are increasingly looking for ways to leverage and monetize their data. Data ecosystems, where data is shared and exchanged between different stakeholders, can provide a powerful way to create value from enterprise data.
