Atlantinsilta | Jätkäsaaren uudessa sillassa näkyy YIT:n ja Steelhousen kädenjälki
Handprint of YIT and Steelhouse is visible in the new bridge of Jätkäsaari

The handsome new Atlantic Bridge in Jätkäsaari was opened to traffic in May. Ordered by the City of Helsinki, the bridge, which is about a hundred meters long, serves both residents of the area and passengers arriving at the West Terminal, and carries light traffic, trams and vehicles.

The contractor of bridge project was YIT Suomi Oy, the bridge was designed by WSP and Ramboll was responsible for the design of the areas and structures around the bridge. For the project, Steelhouse supplied surface-finished steel structures made of stainless steel. Steelhouse's delivery included design, workshop manufacturing as well as the installation works in the challenging construction site.

YIT's project manager Jarno Ylönen says that the marine, erosive environment required the use of very durable materials and surface treatment solutions, which are familiar to Steelhouse. "We overcame the challenges in close cooperation with the planning department of the end customer and Steelhouse, and the end result was a truly impressive and excellently suited entity", states Ylönen.

The construction of the Atlantic Bridge was a massive project that required, among other things, a considerable amount of foundation construction and support piling. The construction of the watershed bridge required underwater diving, excavation and concreting work, and as a whole, the tight-schedule contract required diverse expertise and close cooperation between the operators.

The end result of the project is a magnificently visual bridge, with special features such as V-shaped columns coated with shiny stainless steel, and a massive railing. The retaining walls of the waterfront have white concrete shell elements, whose wavy design adorns the surroundings of the bridge. The visuality is complemented by special lighting for columns, curbs and railings of the bridge.
