A colossal bridge linking two islands has lastly opened its doorways – and never a single automobile is in sight. The mammoth 1,200-metre (4,000ft) construction is extensively believed to be the longest pedestrian bridge on the planet.
Situated close to the Finnish capital of Helsinki – only a three-hour flight from London – the bridge connects the islands of Laajasalo and Korkeasaari, whereas additionally holding the title of Finland’s longest and tallest bridge.

As a part of a dedication to sustainability, the large construction is the “world’s longest bridge devoted solely to trams, pedestrians and cyclists,” in accordance with a spokesperson for designers Knight Architects.
“Unusually for a construction of this scale, Kruunuvuori Bridge prioritises sustainable motion having been conceived solely for trams, pedestrians and cyclists,” the agency mentioned. “This basic choice redefines the position of the bridge from a bit of transport infrastructure to a civic house in its personal proper.”
The €150m (£126m) Kruunuvuori bridge is certainly one of six being constructed as a part of a £505m venture that may lengthen the tram community roughly six miles from town centre to Laajasalo, the place a major new housing improvement is at the moment being constructed.
The common particular person would take roughly quarter-hour to cross the bridge on foot. “Because the longest and tallest bridge in Finland, its central diamond is a serious new addition to Helsinki’s skyline,” architect Tom Osborne informed Newsweek. “The bridge is a crucial hyperlink to a brand new neighborhood and a catalyst for sustainable progress.” The bridge’s width ranges from 49 toes to 62 toes – with the broadest sections positioned across the pylon – boasting a 65-foot most clearance.
The bridge shouldn’t be solely huge, however its anticipated lifespan far exceeds that of comparable buildings. “120 years could be a typical design life for bridges of this scale,” Tom mentioned, assuring that the Kruunuvuori Bridge ought to final for about 200 years.
“It’s a huge bridge and due to this fact a giant funding. However taking a 200-year place on the returns of that funding – in each monetary and local weather phrases – exhibits that huge tasks should be paired with a long-term view.”

Osborne informed New Civil Engineer that there was sound reasoning behind establishing such a towering construction in what is mostly fairly a low-lying metropolis: “Constructing one thing that’s fairly tall and distinctive was maybe not the apparent factor however there was a superb motive. Having a central tower allowed the skyline at deck stage to be a lot much less cluttered than having many smaller towers.”
He added: “The water will get fairly deep on both aspect of the tower, and so having smaller spans would have been dearer.”
The architects have been required to issue within the harsh Finnish winters when designing the in depth chain of bridges. In a press launch, Knight Architects defined that the bridge’s keep cables are “designed to stay in fixed slight movement” every time the wind blows – serving to forestall ice buildup. The cables are encased in a textured plastic coating that trigger ice to interrupt into wonderful particles quite than forming into massive icicles.

The bridge will moreover function a complicated wind warning system, whereby digital indicators at both finish will show alerts every time highly effective gusts are detected.
Osborne added that he hopes the bridge would be the first of a brand new era of buildings which can be constructed with an eye fixed to the long run: “Over the following 200 years, I hope this diamond turns into not solely an emblem of its place, however an emblem of a shift in direction of extra sustainable methods of dwelling,” he mentioned.
