August 27th, 2014 (InsideCostaRica.com) Experts from the National Laboratory of Materials and Structural Models (LANAMME) are warning that immediate intervention is required to repair serious faults on the Taiwan Friendship Bridge (Puente La Amistad de Taiwán) over the Tempisque River in Guanacaste that, in the worst case, could lead to the collapse of the structure.
LANAMME warns that the most serious concern is significant damage to the expansion joint that connects the two sections of the bridge.
Other problems include significant metal fatigue and broken concrete in the bridge’s supporting structure that is exposing reinforcing steel to the elements.
The problems are believed to be the result of damage caused by several earthquakes over the years that has never been repaired.
On October 22, 2009, a passenger bus crossing a suspension bridge over the Tarcoles River in Turrubares plunged into the river below after the bridge collapsed, killing five and injuring thirty.
