The projects comprise Ho Chi Minh City's Ring Road 3, the first phase of the Bien Hoa-Vung Tau Expressway, and the first phase of the Khanh Hoa-Buon Ma Thuot Expressway.
Speaking at the ceremony, Chinh reiterated the target of building around 5,000km of expressways by 2030, with 3,000km set by 2025 and 2,000km for the remaining years.
However, he said, only 1,729 km have been put into service, stressing the huge workload ahead.
The three projects are scheduled to be completed in 2025 and put into operation in 2026.
The Prime Minister noted their special significance as they cross the central, Central Highlands and southwestern regions where not many expressways run through.
He asked relevant sides to ensure the quality and progress of the projects.
He also stressed the need to ensure rights and legal interests of residents, and harmonise interests of the State, people and businesses./.
