通麥天險位於西藏林芝市波密縣通麥鎮，是G318國道（川藏線）歷史上最險峻的咽喉路段，以「天路工程奇蹟、地質災害標本、川藏線精神地標」三大核心價值著稱，被譽為「中國公路災害防治的活體博物館」。

The Tongmai Dangerous Road is located in Tongmai Town, Bomi County, Nyingchi City, Tibet. It is the most treacherous and critical passage in the history of National Highway G318 (Sichuan-Tibet Highway). Renowned for three core values—"a miracle of alpine road engineering, a specimen of geological hazards, and a spiritual landmark of the Sichuan-Tibet Highway"—it is acclaimed as the "Living Museum of Road Disaster Prevention and Control in China."​
