The Skerjabru cable bridge formed a part of an urban proposal for Löngusker in Reykjavik, Iceland.
The Longusker development is a 53 hectare proposal for a new neighbourhood built on 5 artificial islands located on shallow shoals in the Skerjafjordur bay. The development consists of a densely built mix use neighbourhood with app. 800 quality residential units, retail and commercial developments. A single avenue connected the 5 islands with pedestrian network integrating the neighbourhood into one whole. Piers and marinas circulated the island and access was provided by a road connection to both the city centre of Reykjavik and the Alftanes peninsula.
Skerjafjörður bridge
The road connection across the Skerjafjordur bay has the potential to be developed as an independent project and could serve to intertwine the existing linear traffic condition of the city, turning it into a ring-road typology.
This new connection would open up the area of Alftanes for urban development, providing much needed housing and commercial space for the city.
While most of the road is built on land-reclamation with two bridges spanning the deepest areas of the bay. A long low bridge is located on the north side of the road, with a tall cable bridge sitting on the south side of the road. Both bridges are necessary to allow water circulation, while the tall bridge is designed to allow the passage of sail-boats into marinas existing and proposed in the bay.
Brief
The Reykjavik conurbation in Iceland is a collection of 8 municipalities without a common city government or united planning policy. Over time the city has developed out along major routes entering the city putting a strain on infrastructure and creating a low density sprawl. The tugged coastline has magnified this progression. Löngusker are a series of tidal islands in the bay of Skerjafjordur at the heart of the conurbation. The aim of this speculative development was twofold, to propose a dense new development on an artificial island on top of Löngusker. To propose a transport connection to the two sides of the bay, which would also act as a catalyst for major urban reversal.
The development would have to be a quality mixed development, an island village, with a developed and well thought out access to the sea. The primary aims would be sustainability and quality of life. The transport infrastructure within the island and the connection to the coastlines should have a clear hierarchy of use, with pedestrians at the top, followed by cycling, public transport and private automobiles at the bottom. The use of the sea for transportation and leisure would be encouraged. The new connection will make the Skerjafjordur bay the central urban space in the city. This will automatically lead to the tall bridge becoming an iconic structure and the design should reflect this.
Proposal
The Longusker development is a 53 hectare proposal for a new neighbourhood built on 5 artificial islands located on shallow shoals in the Skerjafjordur bay. The development consists of a densely built mix use neighbourhood with app. 800 quality residential units alongside retail and commercial developments. A single automobile avenue connects the 5 islands with pedestrian network integrating the neighbourhood into one whole. Docks and marinas circulated the island with seawalls creating a series of sheltered harbours. Access to the mainland was provided by a road connection to both the city centre of Reykjavik to the north and the Alftanes peninsula to the south.
The Bridge
While most of the road is built on land-reclamation with two bridges spanning the deepest areas of the bay. A long low bridge is located on the north side of the road, with a tall cable bridge sitting on the south side of the road. Both bridges are necessary to allow water circulation, while the tall bridge is designed to allow the passage of sail-boats into marinas existing and proposed in the bay. The new bridge design is based on historic Norse artisanship and emphasises the geometry of the rising bridge deck.
The new bay connection creates an opportunity for a main circle transport infrastructure connecting the main municipalities around one core urban strategy. This new connection would open up the area of Alftanes for urban development, providing much needed housing and commercial space for the city.
