Phuket –
In a transformative move for Thailand’s southern infrastructure, the Department of Highways has officially launched a landmark initiative to boost traffic efficiency and regional growth: the design and construction of the nation’s first-ever suspension bridge linking Phang Nga and Phuket.
The Department of Highway told the Phuket Express that this week, a public seminar was held at the Royal Phuket City Hotel to present the preliminary details of the project. Led by local government officials and representatives from consulting firms the gathering drew over 100 participants from community leaders to representatives from schools, hospitals, private organizations, and media outlets. The seminar highlighted key insights into Thailand’s ambitious plans for Highway Route 402 and its integration with the MR9 intercity highway from Surat Thani to Phuket.
The centerpiece of the project is a 1,000-meter suspension bridge spanning the Andaman Sea, connecting Ban Tha Nun in Phang Nga to Mai Khao in northern Phuket. Designed without support pillars in the sea to minimize environmental impact, the bridge is expected to become a stunning new landmark, blending engineering excellence with ecological sensitivity. In addition to facilitating smoother traffic flow and reducing congestion, the bridge is poised to become a major driver of tourism by offering a scenic gateway into Phuket.
The project includes comprehensive upgrades to existing structures such as the historic Sarasin Bridge, alongside new alignments that connect the proposed bridge to emerging expressway routes like the Muang Mai–Kathu corridor and the Patong Tunnel. These developments aim to modernize road transport and integrate it more effectively with railway systems—a key goal of Thailand’s Ministry of Transport.
The project is currently undergoing rigorous studies, including an Environmental Impact Assessment (EIA), to ensure responsible development. The design phase is scheduled for completion by the end of 2026. By then, officials will finalize alignments and key road links that will transform how travelers move between Phuket and the mainland.
While public opinion largely supports the new roadway for its potential to relieve traffic and stimulate economic growth, residents raised thoughtful concerns. Issues such as disruption to local communities, impact on schools, safety checkpoints, and the effect on coral reefs and sea turtle nesting sites have sparked calls for detailed mitigation strategies.
The Provincial Waterworks Authority also highlighted plans to incorporate water pipelines beneath the Sarasin Bridge, calling for coordination with infrastructure upgrades. All feedback from this initial consultation will be incorporated into the final design plan to ensure that the project aligns with community needs, ecological preservation, and long-term sustainability.
