Rehabilitation of the east access to the Centenary Bridge in Panama
Panama
This emergency project that was requested by the Ministry of Public Works was due to a landslide caused by the rainfall in December 2010 and includes the repairs to the Centenary Bridge access by prior stabilisation of the dual carriageway with the construction of a 1.0-metre diameter secant pile wall of up to 42 metre length. This wall was secured by 150-tonne active anchors distributed in two lines. Once the ground was stabilised, the roadway was reconstructed by a "Y" shaped reinforced concrete bridge of six spans cemented over 1.50-metre diameter piles, on which reinforced concrete capping was executed, 1.50-metre diameter piers and the deck consisting of prefabricated, pre-stressed concrete beams with 1.35-metre edge depth.
In addition, other fill-in and drainage works were carried out at the slipped slope foot, with the construction of a channel and the execution of Californian drains distributed all along the slope foot.
