Longteng Broken Bridge 龍騰斷橋 is a historic roadside attraction in the hills of Sanyi 三義 in Miaoli 苗栗, Taiwan. More formally known as Yutengping Broken Bridge 魚藤坪斷橋, it was originally constructed in 1907 during the Japanese colonial era, connecting Zhunan 竹南 and Taichung 台中 along what is now known as the Old Mountain Line 舊山線. The bridge collapsed during the devastating 1935 Hsinchu-Taichung Earthquake but the ruins were never cleared away. Further damage was done in the 921 Earthquake in 1999. Several years later it was designated a historic site by the Miaoli County government and subsequently developed for tourism along with the former Shengxing Station 勝興車站.
