The new Serelles bridge links the new residential area of Serelles with the old city of Alcoy in Spain. The municipality of Alcoy chose Degree of Freedom’s design competition entry. The bridge spans at a height of 30m over the Cint Gorge. It includes two vehicle lanes, a footpath and a cycle path.
The proposed solution includes 40m of access road and a bridge with a total length of 89. m, divided into two spans. The main span of 58.5m length is a composite cross-section, formed from a reinforced concrete deck over a steel truss. The short span is 30.5m long of reinforced concrete construction.
The width of the deck at the top is 13m, with a span of 6.5m between the longitudinal beams (between top chords of trusses at main span). The sides are cantilevered 3.25m at the main span and 2.75m at the short span, due to the increased width of the concrete girders.
The depth of the deck is 3,5m at the connection between the main and the short spans over the inclined central pier. The steel bottom chords, bracing between these and the diagonals are all made of steel circular hollow sections.
