A landslide occurred on the southbound Xizhi section of National Freeway No. 1 on Nov. 1. Repairs are underway, although the Xizhi interchange remains closed. There was a purple alert at around 7 a.m. on Nov. 2 for southbound traffic between Wudu and Xizhi. The Freeway Bureau says the repairs will be completed by Nov. 4.
Police officers direct traffic at an intersection during rush hour. Nearly 100 police officers were sent to direct traffic on the morning of Nov. 2. New Taipei City Mayor Hou Yu-ih was also present at the scene to inspect repairs.
Hou Yu-ih, Mayor, New Taipei City: “I hope the road can be reopened as soon as possible, and I would recommend installing additional automatic monitoring systems at places prone to landslides.”
A landslide occurred on the southbound Xizhi section of National Freeway No. 1 on Nov. 1 after several straight days of heavy rain. Repairs are underway, and the lanes have been reopened to traffic. However, motorists are currently unable to exit onto the Xizhi interchange from southbound lanes and the southbound interchange for the Xizhi system that leads to National Freeway No. 3 is also closed.
Chang Chung-chih, Dep. Director, N. Region Branch Office, Freeway Bureau: “The area of the dirt and rocks that fell down was pretty large, so it will take some time to clear it all away. Next, we need reinforcements to prevent further dirt and rocks from falling down.”
The closures led to a traffic jam and a purple alert was issued for southbound traffic between Wudu and Xizhi at 7 a.m. on Nov. 2, affecting southbound commuters. The Freeway Bureau advised motorists to get off the interchange earlier or take alternative routes such as Provincial Highway 5. It promised to complete the repairs by Nov. 4.
員警冒著雨勢，站在路口指揮交通，上班時間不斷湧現車潮，道路被車輛擠滿，警力出動近百名引導，疏散車流，新北市長侯友宜今（2）日一早也前往視察，要求加速搶通。
新北市長侯友宜指出：「希望能夠盡快搶通，（建議）在土石流邊坡的地區多裝設自動監測系統。」
受到連日大雨影響，國1南向汐止段外側邊坡發生土石滑落，經過搶修，雖然國1南向主線已經恢復通行，不過要從汐止南向出口下交流道依舊無法通行；汐止系統南向交流道轉往國道3號，同樣持續管制封閉。
高公局副分局長張崇智表示：「坍塌下來的土石的面積量也比較大，要一些時間清理，第2個是說，要先做一個加固，避免上面的土石再繼續下來。」
出口匝道不通讓交通大打結，上午7時多，國1南下五堵往汐止段一度大塞車，出現紫爆，從北往南的通勤族大受影響，高公局除了建議提前下交流道，或是改走台5線等替代道路，也允諾會在4日週五盡速搶通。
