Jakarta Vice Governor Rano Karno inspected the repairs to the collapsed section of Jalan Raya Lenteng Agung in Srengseng Sawah, Jagakarsa, South Jakarta, on Tuesday (6/2).

Rano said he was impressed by the speed of the repairs, noting that both lanes had been reopened to traffic just five days after the road collapse.

“I am very surprised that this road has become passable again within five days and is now in fairly good condition,” he said.

Rano explained that the road collapse, which occurred on Thursday (5/28), was caused by the deterioration of an armco steel culvert beneath the road due to age.

“There is a drainage channel beneath the road that carries water from the UI Reservoir in Depok,” he added.

Rano said the repairs were carried out day and night over a four-day period. The operation involved heavy equipment, which required traffic engineering measures for vehicles traveling from Jakarta toward Depok on Monday (6/1).

According to Rano, the damaged culvert section was replaced with a K-400 concrete box culvert. The road surface was then reinforced through concrete paving.

Although the repairs have been completed, Rano acknowledged that additional work is still needed along the roadside, including shoulder improvements and the removal of remaining construction materials to prevent traffic congestion.

“This road, which connects Jakarta and Depok, is a vital access route. I appreciate the Water Resources Agency and Public Works Agency for completing the repairs in such a short time,” he asserted.

Regarding the possibility of similar incidents elsewhere, Rano acknowledged that many underground culverts in Jakarta are still made of armco steel pipes that are more than 30 years old.

Therefore, he has instructed the Water Resources Agency to immediately conduct an inventory and carry out repairs in stages.

“Earlier, I discussed this with the Water Resources Agency and asked them to prepare. We need to be realistic about the situation so that if something happens, we already know what steps to take,” he noted.
