Tunneling for Doha Metro to be completed this fall
A massive tunnel boring machine (TBM) operating on a section of the Doha Metro was slated to break ground near the Doha Golf Club this morning.
The breakthrough, which is being delayed until the evening because of technical difficulties, will mean Qatar Rail contractors have finished digging the tunnels for the northern section of the Red Line.
Approximately 85 percent of the tunneling work has now been completed on the project, up from 77 percent roughly six weeks ago. Tunneling is scheduled to completely wrap up by this autumn.
