Thanks to Korean companies Saudi Arabia has public transport.

Samsung C&T received contract in 2013 for 6 metro lines in Riyadh. Construction started in 2014. Planned to finish in October 2018 but Corona Virus (COVID-19) delay finish to late 2022.

Good opportunity for Samsung C&T to improve Tunnel Boring Machine use.
