Infrastructure rarely makes headlines, but the systems that keep traffic moving matter more to property values than most buyers realise. When a city invests in smart traffic management, it is not just about convenience. It is about sustained accessibility, demand and confidence in high-traffic zones.
Phuket’s Highways Office has announced overnight closures for both the Darasamut and Samkong underpasses through May 31 as crews install new electrical systems, license plate recognition cameras and internet-connected traffic signs. The work is part of Phuket’s broader Smart City infrastructure programme.
Both underpasses will close nightly from 8pm to 6am. Motorists are advised to use alternative routes during those hours.
What the upgrades include
The project involves removing outdated lighting and installing a modern electrical system with remote power outage notification capability. Officials are also installing license plate recognition cameras and upgrading existing traffic signs to variable message signs connected to the internet.
According to the Phuket Highways Office, the work supports the establishment of a remote control and monitoring centre designed to improve efficiency and safety across Phuket’s tunnel infrastructure.
The Samkong Underpass closures began on May 23. The Darasamut Underpass closures begin May 27. Both will continue nightly through May 31.
Why infrastructure investment matters for property
The Darasamut and Samkong underpasses serve central Phuket areas with concentrated residential, commercial and retail activity. Sustained investment in these corridors signals government commitment to maintaining access and reducing congestion in zones where demand is already strong.
For buyers considering property near these routes, the upgrades suggest two things. First, the infrastructure is being modernised rather than neglected. Second, the investment in monitoring and traffic management points to an expectation of continued use and growth.
Smart traffic systems are not decorative. They allow real-time adjustments to flow, faster incident response and better data on usage patterns. In practical terms, that means fewer delays, improved safety and more predictable travel times for residents, tenants and visitors.
The wider Smart City context
The underpass upgrades are part of Phuket’s broader Smart City programme, which includes digital infrastructure, monitoring systems and connectivity improvements across public facilities.
While the term ‘Smart City’ is often used loosely, the practical focus here is clear: remote monitoring, improved electrical reliability and automated traffic management. These are operational improvements, not branding exercises.
For property owners in central Phuket, the relevance is straightforward. Infrastructure upgrades in high-traffic areas help sustain accessibility, which in turn supports rental demand, commercial activity and long-term property appeal.
What remains to watch
The overnight closures are scheduled to end May 31. What is not yet clear is whether additional phases of Smart City upgrades are planned for other underpasses or key corridors.
The Phuket Highways Office has not announced further closures beyond this initial phase, but the establishment of a remote monitoring centre suggests ongoing investment in connected infrastructure across the island.
For buyers, sellers and agents, the detail worth noting is that central Phuket continues to receive targeted infrastructure attention, even during periods when tourism fluctuates. That consistency matters more than individual projects.
