Metro traffic on the Vuosaari branch in Helsinki will be suspended from 5 May to 28 September 2025 due to essential repairs on the Vuosaari metro bridge, City Transport Ltd has announced.
During the disruption, trains will not run to Rastila or Vuosaari stations. The repairs require a full traffic shutdown, as maintaining partial service would pose technical and quality risks. HSL will provide replacement transport services throughout the closure.
Preparatory works have already been underway for several weeks. Workers have been using high-pressure water jets to remove the surface concrete layer from bridge pillars to allow immediate access for full repair operations once the shutdown begins.
The repair project will address cracks found in the bridge’s concrete structures and leaks in the deck slab, as identified in special inspections. In addition, waterproofing and drainage systems will be replaced. The overhaul is expected to extend the bridge’s lifespan by several decades.
The main contractor for the bridge repairs is MPV-Infrarakenne Oy, while Delete Finland Oy is handling the hydro-demolition work.
Further renovations are also planned at Vuosaari metro station. These include renewing the platform tiles, repairing the heating system beneath the platform surface, upgrading accessibility features, and replacing escalators and lighting systems. Rakennuspartio Oy is managing the station works, with electrical installations handled by L&T Oy.
City Transport Ltd confirmed that Itäkeskus area metro switches will also be replaced, along with cable ducts and track power circuits. These additional works may affect service frequencies between Siilitie, Itäkeskus and Puotila during the summer. HSL will release detailed information closer to the time.
At Rastila station, lighting will be modernised, and Helsinki Art Museum HAM will carry out conservation work on a trackside artwork.
The full metro closure is being kept as short as possible. Although the bridge renovation itself will continue into next year, normal metro service between Itäkeskus and Vuosaari is expected to resume after the summer.
