Mr. Trieu Van Toan - Deputy Construction Commander (Bac Trung Nam Construction Joint Stock Company) - said that the unit is constructing T24 pillar - the main pillar of Dai Ngai 1 bridge, with more than 150 engineers and workers. It is expected to complete all deposits before November 20, 2025, 2 months ahead of schedule to move to the bridge deck construction phase.

According to Mr. Toan, the construction area near the estuary is often affected by strong winds and tides, but the contractor has proactively used large cranes and 5,000-ton barges to ensure stability during construction. In the face of high tides, the plan to close the construction floor has been approved by the investor and consultant, helping to effectively control the impact of water levels on progress.
