Construction began in April on the main structure of the Suzhou-Wuxi-Changzhou highway project. The highway, which goes under Taihu Lake in East China's Jiangsu province, has undergone an intense period of construction over the last 22 months.

Undertaken by China Communications Construction Company Ltd (CCCC) Third Harbor Engineering Co, the work on the main structure is being carried out by thousands of workers under the lead of Guo Tailiang and Zhang Wei.

Guo and Zhang are both experienced young engineers of the post-90s and are working without a break every day to manage the production schedule, and organize and control safety and quality on-site.

"Taihu Lake is a famous scenic place but we've never got to enjoy it," they said. "We hope to complete the construction soon and drive on the highway along Taihu Lake in Wuxi."

The construction of the highway started in June 2017 and is expected to cost 15.91 billion yuan ($2.4 billion). The tunnel is scheduled to open in 2021.

The 43.6-meter wide highway tunnel on the Changzhou-Wuxi Highway will run for 10.8 kilometers under Taihu Lake, making it the longest and widest underwater highway tunnel in China.
