Every Phuket sales brochure has an infrastructure page. It shows a light rail line, a tunnel to Patong and an expressway, and it invites the reader to assume all three are imminent. The useful question is not whether these projects exist. It is which stage each one has actually reached.
How far along is it, really
The infrastructure claim ladder
Nine stages between an idea and a road. A brochure rarely says which one its project has reached.
Compiled by us from the public record for both projects, read 24 September 2026. The light rail reached cabinet approval on 11 September 2018 and has not started construction; the MRTA board acknowledged in July 2025 that construction is now scheduled for September 2028 with operation in December 2031. The Kathu to Patong expressway has nearly completed land acquisition ahead of a cabinet review expected in the fourth quarter of 2026.
The light rail has been coming for twenty-one years
The public record is unusually clear on this one. A mass transit line for Phuket was proposed in 2005. The Ministry of Transport approved it in principle in November 2015. The MRTA approved the design in April 2017. The cabinet approved the project on 11 September 2018.
The scheme is 58.6 kilometres with 24 stations, running north to south from Takua Thung in Phang Nga to Chalong, with a first phase of 41.7 kilometres and 21 stations. The estimate was 23.5 billion baht in 2015 and 35 billion baht by 2019.
It was originally due to open in 2024. In July 2025 the MRTA board acknowledged that construction is now scheduled to begin in September 2028, with operation in December 2031. That is a seven year slip on the opening date, and the project has still not broken ground.
Twenty-one years from concept to a construction start that has not happened yet. That is the project on the infrastructure page of the brochure.
The tunnel is real, small, and a decade away
The Kathu to Patong expressway is the project most likely to actually change how the island moves, and it is worth being precise about its scale. Phase one is just under four kilometres long, of which 1.85 kilometres is tunnel. The tunnel bore was revised down from seventeen metres wide to fourteen.
Land acquisition was about 99 percent complete during 2026, with a cabinet review expected in the fourth quarter of 2026, construction projected to start in 2027, a build period of roughly four years, and an opening around 2031. Tolls have been indicated at twenty baht for a car and ten for a motorcycle.
A second phase, roughly 30.6 kilometres from Muang Mai through Koh Kaew to Kathu, would connect the airport end to the same route. It has its own separate approval and construction timeline, which is another way of saying it is further away.
What infrastructure actually does to land value
The mechanism is narrower than the brochures suggest, and it works in three specific ways.
- It moves value at the nodes, not along the line. A rail scheme lifts land within walking distance of stations. Land a kilometre from a station gets the noise and not the benefit. Anyone quoting a rail line as a reason to buy should be able to say which station and how far.
- It prices in at construction start, not at announcement. Markets discount announcements heavily, and they are right to, as twenty-one years of light rail history demonstrates. The repricing happens when the machinery arrives.
- It changes minutes, and minutes are what people pay for. A four kilometre tunnel that removes the Patong hill from a journey is worth more than thirty kilometres of expressway somewhere people do not go. Value follows the reduction in journey time, not the length of the road.
A rail line lifts the land you can walk from. Everywhere else gets the announcement and nothing else.
Three questions for any infrastructure claim
- Which stage is it at? Cabinet approval is stage four of nine. Under construction is stage eight. The distance between them, on this island, has been seven years and counting.
- How far is my plot from the actual benefit? Not from the route. From the station, the junction or the portal.
- What does it change in minutes? If the answer cannot be given in minutes saved on a journey somebody actually makes, it is not an infrastructure benefit, it is a map.
What has actually been delivered
It would be unfair to imply that Phuket has not built anything. The island has a genuinely international airport, a bypass road that works, private hospitals to international standard including one with Joint Commission International accreditation held since December 2012, and fixed broadband that put Thailand thirteenth in the world at a median 237.05 Mbps in the Speedtest Global Index for March 2025.
That delivered infrastructure is the reason Phuket supports a genuine long stay and remote working market rather than only a holiday market. It is a stronger argument for the island than any of the announced projects, and it has the advantage of already existing.
Cherngtalay and Layan, with the ladder applied
This corridor is where the infrastructure argument is made most often, so it is the fair place to test the framework. Three projects are routinely cited for it, and they sit at three completely different stages.
- The Cherngtalay ring road. Described in agency material as being in the design phase with land acquisition ongoing, at an indicated ฿1.2 to 1.8 billion and a completion estimate of 2028 to 2029. On the ladder above that is stage three, and no cabinet approval has been reported.
- Laguna Lakelands. A private masterplan of more than 250 hectares, with phase one infrastructure described as around 60 percent complete and first residential deliveries planned for the second half of 2027. This is the one in the list that is genuinely being built, which makes it the one worth weighting.
- Phuket airport. Here the published numbers diverge sharply depending on who is publishing them, and the divergence is instructive.
Two versions of the same airport
The airport operator, AOT, outlined an expansion of approximately ฿6 billion to take annual capacity from 12.5 million passengers to not less than 18 million, with construction from November 2024 over about three years and completion expected in 2027, raising hourly movements from twenty flights to twenty-five.
Agency material circulating in 2026 describes instead a $3.2 billion programme taking the airport from 12.5 million to 30 million passengers a year by 2032, with a second terminal in 2027 and a new runway by 2029.
We are not going to adjudicate between those. We are going to point out that one of the two figures comes from the operator and the other comes from parties who sell property nearby, and that a reader is entitled to weight them accordingly. That is question two of the four at the top of this page, applied to a live example.
The airport operator says six billion baht and eighteen million passengers. The brochures say three point two billion dollars and thirty million. Ask who is publishing the number.
The appreciation forecasts, and who wrote them
The same agency material projects appreciation of 15 to 25 percent over three to five years for areas gaining ring road connectivity, 10 to 20 percent for Bang Tao and Laguna, 10 to 15 percent for Layan as a quiet premium location, and 8 to 15 percent for Nai Yang, Mai Khao and the north. It also cites a precedent, that road improvements around Boat Avenue between 2018 and 2020 were followed by value increases of 15 to 20 percent in adjacent Cherngtalay developments.
Those are forecasts published by parties who sell property in the areas being forecast. They may well prove right. They are not independent, they are not dated to a methodology, and no owner should treat them as a basis for a purchase price.
Why this corridor moved anyway, without any of the forecasts
Here is the part that does not depend on a projection. Cherngtalay is the only stretch of Phuket’s west coast with an established year round services cluster: supermarkets, clinics, international schools, restaurants that stay open in low season and a retail centre that functions in September. That is why the area holds value through the monsoon while purely seasonal beaches do not.
It is also, of the major west coast beaches, among the closest to the airport, which matters to a guest arriving at midnight and to an owner flying in for a long weekend. Layan trades the density for quiet while keeping most of the access, and sits next to protected coastline that cannot be developed, which is a more reliable scarcity argument than any road.
None of that is a forecast. It is the condition of the place today, and it is the reason we would buy there rather than because of a ring road at stage three.
Cherngtalay held its value because the supermarket stays open in September. That is a more durable argument than a road at stage three.
What we tell owners
Buy the location for what it is today, and treat announced infrastructure as an option with no expiry date and no guarantee. If the tunnel opens in 2031 and your land sits at the right end of it, that is a windfall. If it slips again, you still own a house in a place you chose for reasons that had nothing to do with a map in a brochure.
We say the same thing to sellers. A property whose case rests on a project at stage four is a property whose case rests on something outside everybody’s control.
