Classified as a level II traffic project, the Cua Luc 3 Bridge stretches over 2.6 kilometers with six lanes featuring a speed limit of 60 km/h, playing a pivotal role in completing the regional road network. However, the project encountered several challenges during its implementation, including the need to adjust the alignment design to preserve the mangrove ecosystem and logistical issues such as site handover delays, exacerbated by factors like the prolonged COVID-19 pandemic and fluctuating raw material prices. Despite facing a delay of 14 months beyond the initial deadline, the collective efforts of various stakeholders ultimately led to the successful completion of the bridge.

The bridge's architecture features a primary load-bearing arch complemented by two side landscape arches, with the main arch adopting a parabolic shape that spans across Cua Luc Bay. This design concept mirrors the imagery of the sun rising at dawn on Ha Long Bay with its wonderful landscape.

In order to provide both decorative and functional illumination to the central part of the bridge, a dynamic lighting system that could enhance its elegant arches with an artistic game of synchronous lights was required by the city council. Designed and implemented by PhuThanh JSC, leading company specializing in LED technology installations in Vietnam, the lighting scheme aimed to illuminate the bridge's three arches and side edges with captivating light displays.

To achieve this, 465 units of Graph-i-CELL 3 RGB fixtures were installed along the side edge of the bridge, creating colorful spots to enliven its central profile. Additionally, an array of CAPITAL 200 fixtures in RGBW color configuration located at the base of the vertical cables of the primary load-bearing arch, are used to light them up along with the inner part of the arch. Jupiter units were used for the two lower side arches. To complement the lighting scheme, batteries of Capital 300 and Capital 100 were strategically placed to light up the outer profiles of the three arches according to their height. All fixtures were delivered with an additional anti-saline treatment to enhance their resistance to coastal environmental factors. The lighting system is managed via a complex DMX control system, allowing for the programming of countless color scenes and effects.

The result is truly impressive; the bridge has acquired a new identity and has become a captivating attraction at night.
