The Doha Metro project crossed 112 million man hours of completed work in the first week of April, with 89% of tunnelling finished, according to an announcement by Qatar Rail.

The official railway agency of Qatar also said that 35% of the construction work has been completed on the Lusail Light Rail Transit tram project.

Plans for the Doha Metro include 111km of tunnels, of which 99km has already been completed, Qatar Rail said. More than 32,000 workers are currently deployed on the project, the agency added.

The Doha Metro will form the backbone of an integrated public transport system for the Qatari capital, supported by the Lusail tram, a city-wide bus network and dedicated feeder bus services to increase the public transport catchment area.

The agency has announced a completion date of 2019/20 for the first phase of the Doha Metro, while completion of the Lusail project is set for 2020.
