Bai Chay Bridge in Halong Bay: Travel Guide, Activities, Costs & Eco-Tours

Bai Chay Bridge, a modern architectural marvel spanning the Cua Luc Strait in Halong Region, Vietnam, is a vital link connecting the vibrant economic and cultural hubs of Bai Chay and Hon Gai. Stretching 2,487 meters with a 435-meter main span, this cable-stayed bridge, illuminated by colorful LED lights, offers breathtaking panoramic views of Halong Bay, a UNESCO World Heritage Site famed for its emerald waters and limestone karsts. Completed in 2006, it replaced the Bai Chay ferry, boosting regional connectivity and tourism while setting a world record for the longest single-plane cable-stayed bridge at the time. Following Vietnam’s administrative restructuring, Ha Long City has transitioned into Halong Region, reinforcing its global tourism prominence while prioritizing sustainability. Aligned with Quang Ninh’s “Green Tourism” initiative, Bai Chay Bridge enhances eco-friendly exploration through its proximity to sustainable cruises and local attractions.

Vietnam’s administrative reorganization has integrated Ha Long City into Halong Region under Quang Ninh Province, streamlining access to Halong Bay’s attractions, including Bai Chay Bridge, Hạ Long Market, and Vung Vieng Fishing Village. Supported by sustainable infrastructure—cycling paths, electric ferries, and a VND1.7 trillion coastal preservation project—Halong Region facilitates eco-conscious exploration, making Bai Chay Bridge a key highlight in sustainable tourism itineraries.

Bai Chay Bridge, located on National Highway 18A, is a national key project with strategic importance for transportation, economy, and defense. Designed by the Japan Bridge and Structure Institute (JBSI) and built with Japanese ODA funding, it features a 903-meter main bridge with six lanes (four for motorized vehicles, two for pedestrians and rudimentary vehicles) and a 50-meter navigational clearance for vessels. Withstanding level-7 earthquakes and winds up to 180 km/h, its robust design ensures safety and longevity. The bridge’s 8888 LED lights, installed in 2014 at a cost of VND40 billion, create a vibrant, harp-like silhouette at night, enhancing Halong Bay’s aesthetic appeal. By replacing the Bai Chay ferry, it has transformed regional connectivity, fostering tourism growth and economic development. Its proximity to Halong Bay makes it a scenic gateway to the bay’s wonders, offering unforgettable views of Bai Tho Mountain and the karst-studded waters.

Bai Chay Bridge is accessible year-round, with its appeal enhanced by Halong Bay’s tropical monsoon climate. Below are the optimal times to visit based on weather and activities:

• Autumn (September–November): Best Time. Cool and dry, 22–28°C (71.6–82.4°F), low humidity (70–75%), minimal rainfall (50–150 mm/month). Perfect for evening strolls on the bridge’s pedestrian lanes to admire LED lights and Halong Bay views, plus eco-cruises ($80–$200 or 2,000,000–5,000,000 VND). Ideal for photography and Mid-Autumn Festival events.

• Spring (March–May): Warm, 20–30°C (68–82.4°F), moderate humidity (75–80%), low rainfall (<100 mm/month). Great for daytime visits and combining with nearby attractions like Bai Chay Beach, but peak season crowds require early bookings ($100–$250 or 2,500,000–6,250,000 VND).

• Winter (December–February): Cool, 10–22°C (50–71.6°F), low humidity (65–70%), minimal rainfall (<30 mm/month). Fog adds a mystical vibe, ideal for cultural tours and festive events like Tet ($100–$250 or 2,500,000–6,250,000 VND). Evening bridge visits are cozy but require warm clothing.

• Summer (June–August): Hot and humid, 27–34°C (80.6–93.2°F), high humidity (80–90%), frequent showers (300–450 mm/month). Budget-friendly rates ($60–$120 or 1,500,000–3,000,000 VND) make it viable for quick visits, but typhoon risks require weather checks.
