Gov’t Completes Underpasses Construction in Yogyakarta
Ministry of Public Works and Public Housing has completed the construction of two underpasses in Yogyakarta Special Region Province (DIY) namely the Kentungan Underpass and the New Yogyakarta International Airport (NYIA) Underpass. The two underpasses are expected to ease traffic around the new airport NYIA and Kaliurang area.
Head of the Center for National Roads Construction (BBPJN) VII of the Ministry of Public Works and Public Housing Akhmad Cahyadi said that the construction of the Kentungan Underpass has been completed and the Underpass is ready to be inaugurated. The construction has been carried out by PT. Istaka Karya since 2018 with a budget of Rp110 billion.
Kentungan Intersection, located in Sleman Regency, Yogyakarta, has been an area with heavy traffic, with vehicles coming from North Main Road and from Kaliurang Street. The 900-meter Underpass is expected to unravel traffic in the area.
The Kentungan Underpass, Cahyadi added, will also provide access to Kaliurang tourism area. The Underpass, he added, consists of two lanes consisting of 224 meters of tunnel construction (closed slab), as well as east and west road with length of 386 meters and 288 meters respectively.
In the meantime, the New Yogyakarta International Airport (NYIA) Underpass, spanning 1.3 km under the airport, has also been completed and is ready for full operation after it began functioning since 20 December, 2019.
The construction of the Underpass aims to provide access to the Java South Coast National Road connecting Purwokerto and Yogyakarta amidst the construction of the Kulonprogo Airport.
The construction of the NYIA Underpass began in November 2018 at a cost of Rp293 billion sourced from the 2018-2019 Sharia Bonds (SBSN/Sukuk). The construction was conducted by a contractor PT. Wijaya Karya-MCM KSO.
The NYIA Underpass is the longest underpass in Indonesia and consists of tunnel construction (closed slab) spanning 1,095 meters as well as east and west roads with length of 110 meters and 100 meters respectively. The Underpass has a width of 7.85 meters, clearance of 5.2 meters and a side of 18.4 meters. The Underpass will be equipped with an audio system to provide information on safety driving.
To anticipate the occurrence of water puddle, the underpass construction is equipped with a pump and coated with rubber waterstop for concrete walls and floors. In addition, the tunnel is decorated with Yogyakarta-style special ornaments such as Jathilan Dance, Angguk Putri Dance, Kalamakara and Stilir Geblek Renteng.
In addition to connecting Purwokerto with Yogyakarta through Java South Coast National Road, the NYIA Underpass is expected to ease the traffic in Kulon Progo and its surrounding areas as well as to boost economic growth in Kulon Progo Regency. The operation of the NYIA Underpass also supports the Java South Coast National Road as an alternative to the North Coast National Road. (Ministry of Public Works and Public Housing/EN)
