CONSTRUCTION OF THE BRIDGE DAULE–GUAYAQUIL, INCLUDING ACCESS WAYS AND VIADUCTS 

Client: Autonomous Decentralised Government of the Municipalities of Guayaquil, Samborondon and Daule
Location: Guayaquil – Ecuador
Conclusion Year: work in progress

Construction of the bridge Daule – Guayaquil, with a length of 540 meters over river Daule, composed of 9 spans of 60m each and a clearance of approximately 7m. 
The foundations are composed of round metallic piles, driven into the rocky bed, with D=1500mm and thick.=38mm. 
Metallic deck with a width of 26,6 meters, being each span composed of 9 metallic beams of variable web, on which lay the prestressed reinforced concrete pre-slabs and a compression blade of reinforced concrete. 
On the margin of the Guayaquil, it will be built the Cierro Colorado viaduct, with 270 meters of total span, maintaining the bridge structural solution: a mixed structure of reinforced concrete with prestressed pre-slabs. 
On the margin of the Daule, it will be built the La Joya viaduct, with 108 meters of total span, maintaining the structural solution of the Cierro Colorado viaduct: a mixed structure of reinforced concrete with prestressed pre-slabs. 
Several road section will be built connection the two viaducts to the bridge, including drainages, earthworks, retaining walls, finishes, signage, lighting and acoustic barriers.
