Intertwine Bridge, designed by MASS Lab to connect Reykjavík and Kópavogur in Iceland

The new pedestrian and bicycle bridge planned for Reykjavík and Kópavogur in Iceland is part of a broader effort to improve recreational, ecological, and tourist activities in the area. The bridge, which will be anchored on both sides, will support environmentally friendly transportation options such as buses, cyclists, and pedestrians.

The design of the bridge builds upon the existing paths on either side of the shore and introduces a new topography for public use. The intertwining of the paths' soft curves is tailored to the needs of buses, cyclists, and pedestrians, and is anchored on both sides creating a connection between the two cities.

The designers of the bridge have also paid special attention to the flora of the area surrounding the bridge, with the addition of local trees such as conifers, poplars, larches, and ash berries. In addition, the design incorporates elements of the waterfront, such as watersports and cultural spots, to improve the community feeling of the area.

The design of the new pedestrian and bicycle bridge in Reykjavík and Kópavogur, Iceland incorporates a range of features to improve performance and reduce maintenance costs. The structure of the bridge consists of concrete arches that provide space for boat traffic and water activities, and a composite steel-concrete deck reinforces the arches to reduce maintenance needs. The design also minimizes the use of support devices and expansion joints, which typically require the most maintenance.

The bridge is anchored on both sides and rests on a pair of sinusoidal concrete arches that connect monolithically to socket piles. With the bedrock at about 14-15m, the flexibility of the arches and piles allows for total continuity between the components, improving performance and reducing overall maintenance costs.

As a safety feature, web net railings stretch the length of the bridge to encourage pedestrians to enjoy the uninterrupted views of the waves and beachfront. Subtle lighting is used throughout the bridge to provide safe lighting for buses and ensure adequate separation from the railings.
