Recently, according to news from the Urban and Rural Construction Commission of Banan District, Chongqing, the Yunzhuan Mountain Tunnel Project has officially launched preliminary construction work and is expected to break ground in 2018.

The Yunzhuan Mountain Tunnel Project is the western extension of the Longzhouwan Tunnel. It starts at the Fo'er Rock Port Access Road in Banan District, runs west to east through Yunzhuan Mountain, and ends at Oupeng Avenue, with its terminus connecting to the Jiantan River Bridge link road. It is a major corridor linking Yunan Avenue, the Chongqing-Hunan Expressway, the Chongqing-Guizhou Expressway, the Ring Expressway, and S106.

According to the introduction, the Yunzhuan Mountain Tunnel is about 5.47 kilometers long. It is an urban arterial road designed for a speed of 60 kilometers per hour with six lanes in both directions. The project includes two tunnels, Shimazui Tunnel and Banzhulin Tunnel, one interchange at Liujiaogou, and two simple interchanges, with a total investment of about 2.87 billion yuan.

After the Yunzhuan Mountain Tunnel is completed, residents of the Yudong Dajiang area will no longer need to pass through the old town of Yudong when entering or leaving the city, and will be able to reach the core area of Longzhouwan in as little as 10 minutes.
