According to the design, Hung Duc Bridge has a total of 90 spans. Of which, the Lam River overpass consists of 5 spans, constructed using cantilever bridge technology with a large span of up to 120m. The width of the bridge is 17.5m with 4 lanes, with a hard median strip in the middle.

Engineer Nguyen Quang Trung (in charge of Hung Duc Bridge of Cienco 4 Group Joint Stock Company) - said that the most difficult part of the construction of Hung Duc Bridge is the pile driving stage in the middle of Lam River. Each bridge pier is driven with 22 piles, with a depth of minus 50m.

The construction of the foundation of the Lam River pier also identified difficulties when the Lam River water level rose erratically. Workers had to work quickly to avoid the flood season.
