At a special session on June 11, the Dong Nai People's Council approved adjustments to the investment policies for both projects to facilitate faster implementation.
The total investment for Cat Lai Bridge has been increased from more than VND 20.6 trillion (USD 790 million) to over VND 24 trillion, largely due to higher land clearance and resettlement costs.
The bridge will stretch more than 11.6 km and feature six lanes for motor vehicles and two lanes for non-motorised traffic.
Meanwhile, the investment for Long Hung Bridge has been revised upward from more than VND 12.4 trillion to over VND 12.7 trillion. The bridge will be 36 metres wide and include six vehicle lanes and two mixed-traffic lanes.
Both projects will be implemented through a combination of public investment and public-private partnership (PPP) funding.
Authorities said the adjustments reflect updated designs and the need to ensure seamless integration with HCM City's transport network.
The two bridges are expected to be completed in 2029.
According to Dong Nai authorities, the projects will improve regional connectivity, support operations at Long Thanh International Airport and ease pressure on existing transport routes.
Cat Lai Bridge is expected to replace the overloaded Cat Lai ferry service, while Long Hung Bridge will help reduce congestion on Hanoi Highway and the HCM City-Long Thanh-Dau Giay Expressway.
Officials said the projects would also unlock development potential in Dong Nai and strengthen links between the province and HCM City.
