The Senen Extension Underpass development work has reached 98 percent and only leaves the traffic sign installation for the safety of the rider.

Jakarta Bina Marga Agency Head Hard Nugroho expressed, based on the results of trial evaluation on November 9-10, there were several things that need to be improved, such as installing traffic sign, setting traffic light phase and improving traffic jam at the Senen Intersection.

"Nowadays we focus on improvement things in the field in accordance with the results of trial evaluation yesterday," he explained, Monday (11/30).

He expressed that there were frequent crossings of vehicles from Jalan Letjen Suprapto towards Gatot Subroto RSPAD heading to Jalan Kramat Raya or Jalan Salem on the underpass.

So, there should be signs or markers before the vehicle enters the underpass.

"Previously we had installed a marker. If the vehicle wants to enter Kramat or Salemba, please turn left and from the hospital or Atrium turns right in order to avoid crossing," he stated.
