Construction work has been carried out continuously for many days, focusing on the section from Km224+600 to Km224+700 on National Highway 20. Here, construction crews used sheet piles and steel sheets to reinforce the roadbed, preventing cracks from widening. Surface and underground drainage systems were added to reduce pressure on the weak structure, which had been affected by many heavy rains.

After the roadbed has reached stability, the construction unit will install corrugated iron barriers and organize vehicles to rotate on half of the road surface, ensuring safety during the repair process. This measure maintains the smooth flow of the Lien Khuong - Prenn expressway connecting to the center of Da Lat, while reducing the load on Sacom Pass - Tuyen Lam Lake and Ta Nung Pass on Provincial Road 725, which are under high traffic pressure.
