The Sanya Yazhou Bay Science and Technology City section of the G98 Hainan Island Ring Expressway is expected to be completed in 2023. It starts from the Yacheng Interchange and ends at the Ningyuan River Bridge, with a reconstruction length of about 6.36 kilometers.
The roadbed will be transformed into a tunnel, with its construction mainly including one long tunnel and one interchange. The project adopts the standard of a two-way four-lane expressway with a design speed of 100 km per hour.
To date, 40 percent of the total tunnel construction has been completed, with a cumulative construction output value of 1 billion yuan ($150 million). The project is scheduled to complete the mainline construction in 2023. By then, the transportation network of Yazhou Bay Science and Technology City will be further improved.
