The construction of Urumqi's Metro Line 4 has entered a new phase, with excavation of pits and tunnels underway at multiple sites, local media reported.

The project began in 2017 to build 16 stations along a 20.58-kilometer route that starts at Bainiao Lake and ends at Badaowan Vehicle Base.

Four of the line's 16 stations are expected to wrap up construction this year, with an investment of about 3 billion yuan ($190 million). The whole project targets completion and trial runs in 2021.
