Erlang Mountain is the first mountain that the national highway 318 of the South Sichuan-Tibet Line overturns. After the mountain, it reaches Ma'an. This section is now completed at high speed. A tunnel can cross the mountain. The road condition of this section of the national highway is not very good.
The Erlang Mountain Tunnel is 13 kilometers long and has an altitude of more than 1,500 meters. It is the longest tunnel in the Yakang Expressway. It can be passed all year round. There is also an Erlang Mountain Tunnel on National Highway 318, with an altitude of more than 2,000 meters. The main tunnel is long. 4 kilometers.
"Er yeah Erlang Mountain, yeah, yeah, yeah, it is so high", the lyrics have been rendered since childhood, and now I have the opportunity to stand in front of it. With the completion of the 318 Erlang Mountain Tunnel and the Yakang Highway Erlang Mountain Tunnel, the moat becomes a thoroughfare, and Erlang Mountain is no longer an insurmountable barrier. Salute the heroes of road construction! Erlang Mountain Tunnel on National Highway 318 is located on the Erlang Mountain at the junction of Ya'an City and Ganzi Prefecture in Sichuan Province on the Sichuan-Tibet Highway. It starts from the Longdanxi Sichuan-Tibet Line in Tianquan County and ends at the Bietuoshan Sichuan-Tibet Highway in Luding County. 8600 meters. Among them, the Erlang Mountain Tunnel is about 4,180 meters, the Bieto Mountain Tunnel is about 100 meters, and the Hepinggou Bridge is about 120 meters. The road level is a mountain and heavy hill three-level highway, and the entrance is 2,200 meters above sea level. The total investment is 470 million yuan. It is the Sichuan-Tibet line reconstruction project.
The song "Singing Erlang Mountain" by the soldiers who built the highway into Tibet made people know Erlang Mountain, the steep roads of Erlang Mountain, and people's desire to cross the moat to reach beyond. But now, a tunnel can cross the first mountain on the Sichuan-Tibet line in 5 minutes. Lutong Caitong, Ganzi is full of hope.
The Ya'an section of G318 is already a mountainous area. The Erlangshan Tunnel is the longest section in the local area, with a total length of more than 8 kilometers. Presumably such a long tunnel journey is also a great test for novice drivers. After arriving in the tunnel, the speed limit was a little bit depressed, and then there was no big pressure. I saw the LED lights on the top and two walls of the tunnel to cast various fantasy effects, which swept away the sense of boredom.
