This stunning new bridge in Helsinki is designed for cyclists, pedestrians, and trams—but no cars

No cars can cross it; drivers have to take a longer route over an older bridge. On one edge of the island, a former industrial site is now filled with apartment buildings, and the population is quickly expanding across the whole island.

On the bridge, designers focused on the experience for people on foot or bike rather than those on the tram, who will only spend a couple of minutes crossing. “If people feel it’s too difficult or long a walk or cycle ride, then they won’t use it,” says Tom Osborne, director of UK-based Knight Architects, which partnered on the design with WSP Finland.

Halfway across, the bridge widens and there are benches where people can rest and take in the view. In the winter, a snowplow will clear the paths so people can keep riding and walking. (Two tram lines will also begin running either late this year or in 2027.) Because Helsinki is built on an archipelago, the path connects to a few other small islands before reaching the main train station.

Transportation is now the city’s largest source of emissions. Though leadership is encouraging the switch to electric cars, it’s critical to make biking, walking, and transit as appealing as possible, he says. Right now, if someone wants to drive from the island to an office downtown, it’s a longer route. “You can still drive, but [the design is] trying to make people act in their own self interest,” Osborne says. “So if it’s cheaper and faster to cycle, then people will.”
