(Perspective of the package)
The construction of the main bridge has been suspended by the Employer since 2018 because of the design change and the shortage of funding. At present, the package has been resumed and the construction works at site have been implemented after the Employer arranged the financial source and resolved the design matters.
Some photos of the resumption of works on the site of package J1 Ben Luc – Long Thanh expressway project:
Tool Box Meeting at site is carried out every day
Lower/Lift the movable scaffoldings for maintenance before resuming the construction of the cable-stayed bridge structure
