JAKARTA - PT Hutama Karya (Persero) said that the progress of the construction of the Semarang Toll Road "Demak Package 1A has reached 64.2 percent to date.
EVP Corporate Secretary Hutama Karya Adjib Al Hakim explained that the project, which was worked on through Operational Cooperation (KSO) with the Beijing Urban Construction Group (KSO HK-BUCG), implemented the "Sosrobahu" take-off innovation.
This method allows the progress of toll road construction to continue running with a minimum possible disruption to traffic flow on congested arterial roads.
"The installation of rotating runways using the Sosrobahu method is an important milestone in project completion," said Adjib in a written statement, Tuesday, June 10.
Adjib added that Sosrobahu technology is applied to four buffer poles on the Semarang Toll Road "Demak Package 1A (P10, P11, P13 and P14) in the elevated area, which is located between two active arterial roads and close to access to business activities.
The screening took place for approximately two months with the first screening from Pier P11 on May 18, 2025, followed by the second screening of P10 on June 3, 2025, then the third screening of P14 and the last fourth screening of P13 in mid-June 2025, over coordination with the local Transportation Service (Dishub).
To support the implementation so that it runs smoothly, Hutama Karya conducts socialization through social media, local radio channels and installs traffic management signs related to the preparation of Sosrobahu's work around the project area.

"Without Sosrobahu technology, conventional construction processes have the potential to cause congestion, disrupt access to business activities and cause public complaints," he said.
According to Adjib, this method allows the pier head to be built parallel to the road axis, then rotated 90 degrees to the final position using a hydraulic system.
"This technology is ideal for dense urban environments and minimal space for heavy equipment to move," said Adjib.
After completion, he continued, this toll road will increase connectivity and provide protection from the impact of tidal flooding that usually occurs in the coastal areas of Semarang and Demak.
"This toll road is also expected to unravel congestion on national roads, pantura and increase economic productivity in the two regions in Central Java," he concluded.
