The collapsed road section in Lenteng Agung has been successfully secured with robust steel plates as of Friday afternoon, May 29. What was initially a two-lane closure has now been fully reopened, allowing all traffic lanes to become accessible to vehicles once again.
A recent observation by kumparan at 6:45 PM WIB confirmed that a diverse range of vehicles, including motorcycles, private cars, and Transjakarta buses, were able to traverse the previously collapsed area. This swift action significantly eased the immediate traffic concerns following the incident.
Despite the reopening, motorists are advised to exercise caution and reduce their speed when navigating the steel plates covering the damaged road. This precautionary measure is necessary due to a noticeable difference in height between the temporary steel plates and the existing road surface, ensuring safe passage for all.
Traffic flow through the Lenteng Agung area was observed to be busy yet fluid, with minimal disruption. The only slight impediment occurred as vehicles transitioned over the steel plates; beyond this point, traffic could resume normal speeds, indicating effective temporary management of the road collapse site.
Road Collapse Management
Earlier, officers from the South Jakarta Water Resources Sub-agency (Sudin SDA Jaksel) initiated urgent preliminary handling by backfilling the hollow section of the road. Rocks and soil were used to compact the affected area, aiming to stabilize the road surface and ensure safer temporary passage for vehicles.
These proactive measures were crucial in mitigating the severe traffic congestion that had built up around the site of the road collapse. In addition to the backfilling efforts, the Water Resources Agency also promptly installed temporary steel plates at the precise point of the subsidence, further securing the area.
Looking ahead, permanent repair work for the Lenteng Agung road is scheduled to commence at night. This strategic timing is designed to minimize any adverse impact on daytime traffic density. The area currently filled will eventually be re-excavated to facilitate the installation of concrete box culverts, providing a lasting solution to the underlying issue.
The incident at Jalan Raya Lenteng Agung originated from asphalt subsidence that first appeared on Thursday afternoon, May 28. The road, situated near Sate PSK and Gang Empang, subsequently collapsed entirely that same evening, forming a significant sinkhole measuring 2-3 meters deep and 4 meters wide. Investigations revealed the primary cause to be an empty or hollow water channel located directly beneath the roadway.
