Rehabilitation of the east access to the Centenary Bridge in Panama

Rehabilitation of the east access to the Centenary Bridge in 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.


Remarkable aspects

  • The execution period of ten months.
  • The proposed plan of work presented to the Government were fulfilled.
  • Design and construction by FCC.
