Jakartans are bracing themselves for heavier congestion in several parts of the capital city.
The city administration has a number of ongoing and upcoming road construction projects this year, some of which will continue for at least another year before completion.
The head of Bina Marga Agency's overpass and intersection division, Heru Suwondo, said the construction of two overpasses in Permata Hijau and Kuningan in South Jakarta had started earlier this year.
Meanwhile, a bigger project on an elevated highway on Jl. Tendean, also in South Jakarta, will kick off next month.
"Contractors for the Permata Hijau and Kuningan overpasses have completed their designs and the construction work has started.
"In Permata Hijau, the contractors have started to install foundations, while in Kuningan, the contractor is currently widening the road and starting to drill to install foundations," Heru said over the phone on Sunday.
The overpass in Permata Hijau will be built above the railway crossing at the Jl. Patal Senayan intersection to reduce congestion caused by the high traffic of commuter trains (KRL).
The overpass is being built by tender winners PT Lampiri Djaya Abadi, PT Multi Infrastructure and PT Brantas Abispraya. It will be 544 meters long and 10 meters wide.
Meanwhile, the overpass in Kuningan will be located at the intersection between Jl. Gatot Subroto and Jl. Mampang Prapatan.
The one-way overpass, which will be 680 meters long and 5.1 meters wide, will be developed by PT Nindya Karya and will cater to motorists traveling from Pancoran to Semanggi.
