Shenyang’s Secret Tunnel
The 83 tunnel hidden near the end of the Balibao Trail, it was the very first underwater tunnel in Shenyang, which is part of the early Chinese strategic crude oil pipeline project. In the tunnel, two rows of pipelines were buried and allowed for civil use after maintenance in 1999. One to three cents toll was required to go through the tunnel before its closure in 2003. The question is how was this build in that extremely hard time? I can’t imagine.
