Lidingöbron

At a parish meeting in 1802, the inhabitants of Lidingö, at the time a mostly agricultural district, decided to open a venture to realize a pontoon bridge connecting the island to Stockholm.

[1] With the creation of the harbour of Värtahamnen, the original bridge obstructed shipping in the strait, and it was therefore bought by the city of Stockholm in 1883 who replaced it 1884 with a new pontoon bridge, 12 metres (39 ft) wide and with two moveable sections at each end for the passage of ships.

The level of the roadway was only 10–15 centimetres (3.9–5.9 in) over the water surface however, so even moderate winds made crossing the bridge a tough experience.

The part of the bridge passing over water, 724 metres (2,375 ft) long, is made of double box girders with a maximum span of 73.5 metres (241 ft), the entire construction resting on steel poles filled with concrete.

It was opened for bicycles and pedestrians in May 2022, while tram traffic delayed to 26 May 2024 due to technical problems.
