Reconstruction of Dangerous Bridges: An Urgent Need 227<br />

Reconstruction of Dangerous Bridges: An Urgent Need<br />

CHEN, George S.Y.<br />

Abstract<br />

Typhoon Sinlaku hit Taiwan on September 14, 2008, leaving in its wake half a dozen<br />

people killed. Most of those killed were drowned after their cars had plunged into the swollen<br />

river when the Houfeng Bridge collapsed. Many other bridges were damaged in flash floods<br />

triggered by the tropical rainstorm.<br />

The bridges collapsed were seriously damaged because their foundations were washed<br />

bare in the floods. Moreover, the foundations of these bridges had long been eroded. Efforts<br />

have to be redoubled to reinforce the eroded bridge foundations.<br />

Ruined bridges have to be rebuilt. Repairs are urgently needed to make all bridges safe<br />

for traffic. A larger budget is needed to build and repair the unsafe bridges. In addition,<br />

more research is necessary to improve construction of bridges, while better management<br />

must be provided for all the bridges open to traffic.
