Panama's Ministry for Public Works has awarded FCC Construcción de Centroamérica the contract to build the new eastern access bridge to the Centennial Bridge. The contract is worth more than 20 million euro.
FCC to build a new access bridge to Panama's Centennial Bridge

FCC will build a 175-meter reinforced concrete bridge with 5 spans, based on pile caps measuring 1.50 metres in diameter. The project also includes safety and lighting elements on the bridge as well as traffic management on the entire section of the road affected by the landslide.

Repair work on the Centennial Bridge is 63% complete.

Since December, FCC Construction has been repairing damage resulting from the heavy rains at the end of 2010, which led to the collapse of the embankment supporting the three northern lanes of the eastern access to the Centennial Bridge.

To avoid the collapse of the southern lane and, therefore, the entire road, a series of emergency reinforcements were built with a view to later constructing the new bridge where the embankment had been. The reinforcement work is helping to stabilise the debris from the landslide using around 200,000 m3 of armourstone, and to execute drainage trenches. Additionally, shotcrete was applied to the slip plane and ductile iron micropiles were driven into the weakest area and close to the support of the Centennial Bridge.

A pile wall is being anchored on the road median with a view to containing the southern road. The wall will be comprised of 141 perforated piles measuring 1.0 meter in diameter and with an average length of 35 meters, anchored at two heights. Once the anchors have been executed, the bed for the new bridge will be excavated.
