TEMPO.CO, Jakarta - The construction on the first stage of phase II of the MRT which has started from the HI Roundabout to the Kota Station, is targeted for completion in 2024 due to the challenging track conditions.
"The 2.8 kilometer long tunnel stretches from the HI Roundabout to Sarinah, with two underground stations, at Thamrin and Monas. The value of this contract is around Rp4.5 trillion. The construction will continue for 58 months with a target of completion by December 2024," Jakarta MRT President Director William Sabandar said after signing the contract with the Shimizu-Adhi Karya Consortium at the HI Roundabout Station, Jakarta, Monday.
