On September 29, the Dong Nai City People’s Committee and an investor consortium led by Construction Corporation No. 1 (CC1) held a groundbreaking ceremony for the Cat Lai and Long Hung bridge projects. Both are being developed under the public-private partnership (PPP) model.

Under regional planning, the Cat Lai and Long Hung bridges are considered key links in the transport network connecting Ho Chi Minh City and Dong Nai City. Their architectural designs are also intended to create new landmarks within the area’s urban landscape and transport infrastructure.

The Cat Lai Bridge project will span more than 11.6 km, including about 3.6 km of main bridge and approach structures, with total investment exceeding VND24 trillion ($910 million).

The project forms part of an interregional transport corridor stretching from the My Thuy interchange on Ring Road 2 in Cat Lai Ward, Ho Chi Minh City, to the Ben Luc-Long Thanh Expressway in Dai Phuoc Commune, Dong Nai City.

The bridge will have six lanes for motor vehicles and two lanes for non-motorized traffic, with a design speed of 80 kph. It will be a permanent structure built from steel, reinforced concrete and prestressed reinforced concrete.

The main structure will be a cable-stayed bridge with a 450-meter main span and 55 meters of navigational clearance. The clearance is designed to accommodate waterway traffic, including vessels of up to 60,000 deadweight tonnes.

The Long Hung Bridge project will extend approximately 9.8 km, including 3.5 km of main bridge and approach structures. Total investment is estimated at more than VND12.7 trillion ($480 million).

The bridge will have six lanes for motor vehicles and two mixed-traffic lanes, with a design speed of 80 kph. The cable-stayed structure will feature a 350-meter main span and 175-meter-high towers.

The project will connect Long Phuoc Ward in Ho Chi Minh City with An Phuoc Commune in Dong Nai City, helping ease pressure on Hanoi Highway and the Ho Chi Minh City-Long Thanh-Dau Giay Expressway while improving connectivity with Long Thanh airport.

Construction of both bridge projects is being carried out from 2026, with completion and opening scheduled for 2029.

Speaking at the groundbreaking ceremony, Tran Trong Thuy, director of the Dong Nai City Management Board for Investment and Construction of Transport Projects, said the launch of the Cat Lai and Long Hung bridges marked an important milestone, moving the two strategic transport projects connecting Dong Nai City and Ho Chi Minh City into the implementation phase.

According to Thuy, the projects’ large scale, demanding technical requirements and complex construction conditions will require close coordination among government agencies, investors, contractors and consultants.

Thuy said he expected the two projects to be delivered on schedule, helping complete the interregional transport network, expand space for urban and industrial development and logistics, and strengthen connections with Long Thanh airport.
