Design concepts selected for Merihaka and Hakaniemi bridges

Preliminary design concepts have been selected for bridges to be built in Merihaka and Hakaniemi. The concepts will serve as a basis for further bridge design and engineering.

The design concept selected for the Merihaka bridge (see rendering above) will produce a lightweight, pier-like structure that doesn’t block the view from Kalasatama to Pohjoisranta owing to its low elevation. This was considered a merit in terms of the overall cityscape.

The concept also offers new opportunities for the Hanasaari area planning and connections to the inner city, as the design enables a logical cycling and pedestrian connection from the bridge to Hanasaari.

However, no decisions have been made on the connection to Hanasaari, and the implementation of the connection will be determined later.

According to the jury, the design concept selected for the new Hakaniemi bridge (see rendering below) is sculptural and appropriately unconventional.

Alternative design concepts were provided by two consulting firms. Both concepts selected for further bridge design and engineering were provided by Pontek Oy. The selection was made by a jury including members of the Helsinki City Planning Department, Public Works Department and Helsinki City Transport. 

The next stage in the process will consist of general design and engineering to produce plans for bridge architecture, furnishings and railings. The plans will form a part of the Hakaniemi municipal infrastructure plan, which will be completed at the end of 2017. Both bridges are scheduled for construction in the early 2020s.

The Merihaka bridge, included in the Crown Bridges (Kruunusillat) project, will provide a new connection between Merihaka and the southern end of Sompasaari known as Nihti. The bridge will accommodate a tram line, a cycling lane and a pedestrian lane. The bridge clearance will be approximately 2 metres, but the bridge will probably be built with a moveable section to allow for exceptional shipments. The section would be operated with mobile cranes.

The old Hakaniemi bridge, built in 1961, is reaching the end of its service life, and the new Hakaniemi bridge will replace the old one. The new bridge will be located east of the old bridge, which will be demolished. Similar to the old bridge, the new bridge will have 2 + 2 lanes for vehicular traffic, cycling lanes and pedestrian lanes. The clearance of the new bridge will be less than 5 metres.

Crown Bridges project

The Crown Bridges (Kruunusillat) project will give the growing Laajasalo area in eastern Helsinki a fast public transport connection to the city centre. The project involves the construction of a new 10-kilometre tram line, a cycling connection, pedestrian paths and plazas. The new connections provided by the project will improve the entire Helsinki-region rail transport network and the network of the region’s main cycling routes. The most visible part of the project consists of three new bridges, the longest one of which – the 1,200-metre Kruunuvuorensilta – will be the longest bridge in Finland.

In the same connection, a new bridge will be built in Hakaniemi to replace the old bridge, which is reaching the end of its service life.
