Construction has just completed on the 14-mile (23-kilometer) Desheng tunnel—China’s longest single bore, double-track tunnel, which will accommodate high-speed trains traveling at nearly 125 MPH.

Situated close to an active fault zone, project workers had to deal with earthquakes and landslides during the tunnel’s 10-year construction. It is one of 30 such tunnels in the country of a similar size or larger

In contrast, there have been multiple proposals for high-speed rail in the United States in recent years but none has been completed.

In December, President administration announced more than $8 billion in funding for 10 projects including for “the first world-class, high-speed rail projects in our country’s history.”

The newest Chinese tunnel, built by Chinese Railway Group No.2 with design assistance from China Railway Eryuan Engineering Group, sits nearly 10,000 feet (3,000 meters) above sea level.
