The San Sebastián City Council called a competition for the construction of a new 5th bridge over the Urumea River to replace an older existing bridge in poor condition.
The proposal offered a supporting cradle frame that supports the bridge with fanning tensioned cables. The concept was aimed at creating a lightweight bridge system that plays gracefully with the forces using a bent bicycle wheel frame with post-tensioned cables evoking the tense dynamics of “sokatira” a popular rope-pulling sport in Gipuzkoa.
The bridge design has a 24m wide deck, supported by an array of cables above and below the bridge. The deck composition had two lanes for road traffic and a sidewalk for pedestrian traffic, on one side and another sidewalk along with a bike path on the other side.
