Video: Colombia Blows Up Chirajara Bridge

July 13, 2018

Last January 15th, ten workers were killed and eight others injured when the almost complete Chirajara Bridge located on the border of Cundinamarca and Meta provinces, collapsed. The 1,463-foot long cable-stayed bridge was was to be part of the highway that connects the capital Bogota and the city of Villavicencio.

The design called for the bridge to cross a 938-foot gorge, anchored at each end in rugged mountain terrain.

Investigations into the causes of the January collapse were conducted by US engineers Modjeski and Masters who determined a support pile, drilled into a steeply sloping hillside with complex underlying geology, was not able to support its load, resulting in the collapse.

Colombia demo'd the remaining structure on Wednesday for safety reasons. The implosion require 440 pounds of explosives, 9,800 feet of detonating cord, 30 detonators, supervised by eleven experts. Authorities will announce a later date plans for the reconstruction of the bridge.
