Patong –
The Thai Cabinet has approved a major revision to the investment model for the Kathu–Patong expressway project in Phuket, a strategic infrastructure initiative valued at 21 billion baht (approximately USD 570 million). The decision marks a significant shift from a public-private partnership (PPP) approach to direct government-led construction.
Originally slated for private sector investment, the project failed to attract bidders during its first round of procurement. Private firms cited high financial risks and insufficient returns as key deterrents. In response, the Cabinet has authorized the Expressway Authority of Thailand (EXAT) to oversee construction directly, employing a Design & Build contract model with private contractors.
The Kathu–Patong expressway is designed to improve connectivity between Phuket’s popular tourist zones and ease traffic congestion across the island. Phase 1 of the project spans 3.98 kilometers, beginning at Phra Metta Road in Patong and ending at Route 4029 in Kathu. The route will feature four lanes—two for cars and two for motorcycles—and include a tunnel beneath Nakkerd Hill, a key engineering component aimed at minimizing environmental impact.
Construction is expected to begin in late 2025 or early 2026, with completion targeted for 2030.
A second phase of the expressway, covering over 30 kilometers from Muang Mai to Koh Kaew and Kathu, remains under Cabinet review. Authorities hope to proceed with this segment under the original PPP framework, with construction tentatively scheduled to begin in 2027 and open concurrently with Phase 1 in 2030.
The expressway is part of Thailand’s broader strategy to enhance regional infrastructure, support tourism growth, and improve mobility in one of the country’s most economically vital provinces.
