Semarang-Demak Toll Road Is Being Built as Part of a Coastal Barrier
The Semarang-Demak toll road in Central Java, Indonesia, is being built in two sections.
The 16.01-kilometer section between Sayung and Demak has been open since February 2023.
The 10.64-kilometer section between Kaligawe and Sayung is still under construction.
Its three construction segments were reported as 96.55%, 68.70% and 64.79% complete.
Builders are using bamboo piles as part of a construction method described as more environmentally friendly.
The road is part of the Trans-Java toll network and also forms part of a planned giant sea wall.
It is intended to improve travel and economic links while helping protect coastal areas around Semarang and Demak from tidal flooding.
