Heaptalk, Jakarta — The Nusantara Capital City (IKN) toll road is designed for vehicular traffic and features wildlife crossing tunnels. These tunnels, located in Section 3B of the KKT Kariangau-Simpang Tempadung segment, aim to support the movement of local wildlife, including sun bears, while preserving the region’s biodiversity.
According to the Ministry of Public Works (PU), the tunnels are constructed using Corrugated Steel Plates, ensuring durability and environmental compatibility. Four wildlife tunnels span the IKN toll road, measuring 80.77 meters in length, 25.12 meters in width, and 12.74 meters in height.
The tunnels are landscaped with greenery to replicate wildlife’s natural habitat. Deputy Minister of Public Works Diana Kusumastuti inspected the project on Sunday, December 1, emphasizing the importance of environmental sustainability in infrastructure development.
“This initiative is commendable for its focus on conservation and maintaining a sustainable ecosystem. I also want to stress the safety and quality of the bridge materials,” Diana remarked.
The IKN Access Toll Road is progressing across three main sections:
- Section 3A: Karangjoang-KKT Kariangau (13.4 km)
- Section 3B: KKT Kariangau-Simpang Tempadung (7.3 km)
- Section 5A: Simpang Tempadung-Jembatan Pulau Balang (6.7 km)
Diana also visited the Dirgahayu Bridge construction site, part of Section 5A. The bridge design symbolizes Indonesia’s independence and commitment to promoting public welfare. On the other hand, the Dirgahayu bridge contained about 340 meters, comprising a 260-meter minimum span and 40-meter approach spans on each side. The bridge is made of a steel box girder combined with reinforced concrete and prestressed deck box grinders, with a completion target of December 2024.
Integrating wildlife tunnels into the toll road showcases a pioneering effort in sustainable development while ensuring that local ecosystems in East Kalimantan remain protected.
