Take, for example, the repair of Highway 21, which the residents of Namasia Township are eagerly anticipating. Travelers are currently using makeshift paths along streambeds to get through collapsed sections of the road, paths that are washed away every time there's a heavy rain. Several hastily repaired sections of the road are winding and precipitous, and a recent traffic accident along one such stretch cost four lives.
以那瑪夏鄉民殷殷期盼早日修復的台 21 線為例，目前幾個坍方路段都採溪床上搭便道模式，一碰大雨就淹沒不通，若干緊急搶修路段坡道陡峭彎曲，前陣子還出車禍奪走 4 條人命。
