Construction works of the new bridge over the Urumea River, in the Basque Country, ended a year ago. The new bridge connects the Orona facilities in the Epele and Lastaola riverbanks, and substitutes a pre-existent concrete bridge, maintaining the road and access layout and improving hydraulic conditions.
The steel bridge is curved and skewed. Two curved and tapered Warren trusses that separate road and pedestrian traffic form the main structure. A series of transverse beams connecting the lower chord of the trusses support the bridge concrete platform.
The steel elements were painted in a clear ash grey color. Pedestrian pavement has been fabricated using recycled materials, its layout resembling the Orona logo. The handrail is as transparent as possible in order to make the structure visible. This handrail hosts the pedestrian lighting, which is complemented with the trusses' ornamental lighting.
Orona commissioned FHECOR & INJELAN for the detailed bridge design and construction supervision. Urbycolan has been the main contractor of the works. The main subcontractors were Megusa (Steel structure fabrication and erection), Ulma (temporary supports and footbridge), Trelleborg (bearings and joints), Aco (bridge drainage), PVT (pedestrian pavement).
