國道一號五楊高架造價660億，是史上最貴國道，通車才四個多月，路面就出現裂縫，當局計畫之後動工修補，到時夜間得封閉車道。
大太陽的、也沒下雨，地下水卻不斷從管子冒出來，這根管子就插在五楊高架的中央分隔島。
之前的暴雨過後，路面出現裂縫，國工局設置11處點井抽水監測，發現最靠近裂縫的點井出水量最多，確定是地下水排不出來撐破了路面。

第5 第6 第7的水量比較大，水是一個很重要的因素，也是造成這次裂縫的因素。
包商用這根細細長長的反射鏡檢測邊坡有無位移，再看看橋下排水溝，地下水一攤又一攤的。
國工局研議在邊坡或綠帶設置盲溝，疏導積水，一旦施工，就得在夜間封閉車道，計畫在11月動工。
五楊高架造價660億，是史上最貴國道，平均一公里就要16億元, 其中五股-中壢段開放通車才短短四個月，路面出現三處裂縫。
如今這一封，預估得封到明年五月，當初興建的基本功沒做好，如今還得封路補救，實在是擾民又傷財。
The NT$66 billion Wuyang Overpass is one of the government’s flagship freeway projects. But officials are considering closing the overpass at night to conduct major repairs, despite it having been fully open for just four months.
It was a sunny day today with no rain, but water still flows continuously out of this pipe. The pipe was inserted in the central island separating the two sides of the Wuyang Overpass.
The National Expressway Engineering Bureau inserted these pipes in 11 areas. As it moved closer to road surface cracks that emerged in the overpass following recent storms, the amount of water increased. It concluded that the cracks were caused by poor drainage of underground water.

There is greater water volume in the fifth, sixth and seventh (pipes). Water is a major factor behind the cracks.
A worker used a mirror to inspect one problem thought to be caused by the water – the movement of side slopes. A look at drainage areas below the overpass reveals several large puddles.
The National Expressway Engineering Bureau is considering installing a blind drain either in the slope area or the central island. It could begin work in November, but would have to close the overpass at night.
The overpass, located along National Freeway 1 between Wugu and Yangmei, cost NT$66 billion. At NT$1.6 billion per kilometer, it is the nation’s most expensive section of freeway. What’s more, the section between Wugu and Chungli has been open less than four months yet still has three large cracks.
Installation of blind drains would require working into next summer. A quick survey of motorists revealed a common query – how could a road open just four months already require major repairs?
