Cambodia infrastructure: what is open, what is being built and what it actually changes

Dated statuses · airport and expressways · effect on a property · editorial check 19 July 2026

This page is not a list of future promises and not a price forecast. It is a dated tracker of the major projects that can change the country's connectivity and everyday routes. Infrastructure can improve access, but it does not guarantee rent, liquidity or a price rise for any particular apartment — and for each item here we state the date on which the status is known.

Four statuses and what they mean

Open and operating — the facility physically works and there is a confirmed launch date.
Under construction — works have started and the start date is confirmed; the current level of completion needs separate verification.
Design or feasibility stage — the decision to build is still in process, construction has not begun.
Status not confirmed — the project has been announced, but we have no recent primary confirmation of its stage. Such an item must not be used as a fact in a calculation.

The editorial rule is simple: a forecast date from an old news item does not count as a current status. Before publication and before every material update the primary source is opened again. How infrastructure fits into the country-level decision at all is covered in Why Cambodia.

The current tracker

Project	Status	Status date and source	What it changes	What cannot be promised
Phnom Penh Techo International Airport	Open and handling flights	Operations moved on 9 September 2025 · airport operator, Cambodia Airports	A new air gateway for the capital region	An automatic price rise in southern projects
Phnom Penh — Sihanoukville expressway	Open and operating	Opened to traffic on 1 October 2022 · Ministry of Public Works and Transport	Faster road connection between the capital, the port and the coast	Direct yield for any apartment along the route
Phnom Penh — Bavet expressway	Under construction; current progress and completion date not confirmed	Works began on 7 June 2023 · official announcements of the project start. We have no recent completion data as at 19 July 2026	A corridor towards the Vietnamese border	Completion exactly on the original schedule, or price growth along the whole route
Phnom Penh — Siem Reap — Poipet expressway	Status not confirmed: publicly discussed at planning stage, no dated confirmation of the stage	No dated primary confirmation of the current stage as at 19 July 2026	Possible long-term connectivity for the north-west	That construction has started or that timings are known

Editorial verification date for this tracker: 19 July 2026. Rows without a status date are not published on this page as fact.

Siem Reap Angkor airport: open and operating

Siem Reap Angkor International Airport began official commercial operations on 16 October 2023. A 7 December 2025 report by Agence Kampuchea Presse still lists it among Cambodia's newly operational international airports. In a national tracker it therefore belongs as a separate open-and-operating asset, not as part of the unconfirmed Phnom Penh — Siem Reap — Poipet expressway.

A Siem Reap property buyer should calculate the journey to the operating airport rather than the former terminal. Test the actual transfer time to the chosen district, transport availability around the relevant flight times and the round-trip cost. A project presentation that still uses the old airport map or old journey time needs to be recalculated.

1. Phnom Penh Techo International Airport

Phnom Penh's flight operations moved to the new airport on 9 September 2025. It is working infrastructure rather than a future project, and that is exactly why it deserves specific checks against your property rather than enthusiasm:

the real route from the building, not the straight-line distance;
travel time at peak hours and off-peak;
access to the approach road and the quality of the last mile;
the cost of a taxi in both directions;
noise and construction effects in the surroundings;
whether your target tenant needs the airport at all;
whether proximity has been priced in twice — by the developer and by the seller;
whether the daily commute into the centre matters more to the tenant.

The conclusion "this project is closer to the airport, so it will be worth more" does not hold. For some users proximity matters; for most urban tenants everyday access to work, schools and services matters more. A detailed look at the journey itself is in the guide to Techo International Airport and how to get there.

2. Phnom Penh — Sihanoukville expressway

Open since October 2022, the expressway improves the road link between the capital, the port and the coast. It can matter to a buyer who regularly travels between the cities, whose business involves logistics, whose property serves a specific mobile demand, and where the route from the particular building to the expressway entrance is genuinely convenient.

But this is national connectivity, not a standalone rental case for any apartment in the capital or on the coast. Whether a transport project actually adds value is a separate subject: when an airport, bridge or road really raises prices.

Sihanoukville port expansion: three phases, three statuses

An official report dated 1 May 2026 said Phase 1 of the new container terminal was 66.7% complete as at April 2026, with operation expected in early 2027. A loan agreement for Phase 2 was finalised on 13 July 2026, while construction was scheduled to start in September 2026. Phase 3 was still in bid preparation, with an early-2027 start described as the plan.

The expansion should not be given one blanket status. The existing port is operating infrastructure, Phase 1 is under construction, Phase 2 is a financed future phase until physical works are confirmed, and Phase 3 remains preparatory. For a residential property, separately test whether the actual user is connected to port or logistics activity and check truck routes, noise and access to the residential area; higher national port capacity does not prove demand for a particular apartment.

3. Phnom Penh — Bavet expressway

The project relates to the trade corridor towards Vietnam; works began in June 2023. While it is under construction, it is essential to keep strictly apart the original schedule, actual progress, any new official deadline, sections already open, the contractor's statements, and real accessibility for a driver.

We deliberately give neither a completion percentage nor an expected opening date here: we have no recent primary confirmation as at the verification date, and an old planned deadline is not a status. On project pages the completion date of this road must not be stated without a fresh check against ministry publications.

4. Phnom Penh — Siem Reap — Poipet

The corridor has been publicly discussed, but we have no dated confirmation of its current stage, so it sits in the tracker as "status not confirmed". While a project is at planning or feasibility stage it must not enter an investment model as a finished road.

Funan Techo Canal: construction confirmed, housing effect unproven

On 17 May 2026 the Ministry of Public Works and Transport reported that canal construction was continuing in Takeo province. Agence Kampuchea Presse stated on 27 May that work on Section II had begun in April 2026, that the official programme allowed 36 months, and that the route crosses Kandal, Takeo, Kampot and Kep. The defensible tracker status is 'under construction'; the duration remains a planned milestone rather than a guaranteed completion date.

The canal is a water-transport and logistics corridor, so it cannot automatically be turned into a claim about residential rents or prices. For a particular property, verify the confirmed alignment and crossings, construction effects on access, surrounding land use and whether the target user is connected to logistics. Without that link, the canal is macro context rather than a reason to pay an infrastructure premium.

Acceptable wording for a project page: "a long-term corridor is under discussion; the current stage and timings require confirmation." Unacceptable: "a new expressway will soon increase traffic and prices."

How we verify a status

Source priority, top down:

The Ministry of Public Works and Transport.
The official operator of the facility.
A government document or contract.
The financing institution.
A reputable news agency.
A developer statement — only as a statement by an interested party, not as fact.
Social media and marketing materials confirm nothing at all.

For every update we record the source name, the publication date, the verification date, the exact claim being confirmed, the stage, the next expected milestone, any conflicting information and the name of the reviewer. Old entries are not deleted: the reader should be able to see how a status changed and which deadline was once called a plan.

One date does not always describe one event

A status should name the event as well as the date. Phnom Penh flight operations moved to Techo International Airport on 9 September 2025, while the state news agency gives 20 October 2025 as the official launch date. Those statements need not conflict: one describes the operational transfer and the other the formal opening.

When sources give different dates, first separate commercial operations, an opening ceremony, commissioning of one phase and completion of the whole project. If two dates refer to the same event and primary documents do not resolve the difference, the safe label is 'date requires confirmation'. Saying only that an asset 'opened in 2025' is too imprecise for an investment model.

How infrastructure affects a property: seven checks

Actual stage. Open, under construction or merely announced — and as at what date this is known.
The last mile. A major project can be close on the map yet inconvenient because of the entrance, a U-turn or a narrow local road.
Travel time. Check it in several modes — morning, evening, weekend — not once during a quiet hour.
The user. Who needs this route and why, and whether that matches your target tenant.
Negative effects. Noise, dust, traffic, land acquisition, temporary closures, changes in commercial flows, a spoiled view.
Price. How much premium the seller is already asking for the future improvement.
The alternative. Whether a completed property in an established location is available at a comparable price.

The "project delayed" scenario

When buying next to future infrastructure, the financial model has to answer some uncomfortable questions: does the property work today, without the new road; what happens if it slips by one, two or three years; does the entry price survive the promised effect never arriving; can the unit be let now; who buys it without the infrastructure story; which negative effects of construction outlast the construction itself.

A future project should be an upside, not the only reason the purchase is viable. How to model such scenarios is in the investor guide; the macro context is in the review of the economy and property prices.

What we do not include in the tracker

every small road with no independent effect on a buyer's decision;
marketing master-plan elements without permits;
old completion dates that have not been re-verified;
design capacity and passenger numbers where they do not help a decision;
claims of "prices up by X percent" without transaction data;
straight-line distance as the only measure of accessibility.

Looking at a property near new infrastructure? We can check the project's current status against primary sources, the real travel time from the building, and how much infrastructure premium is already in the price.

Frequently asked questions

Is Phnom Penh's new airport already open?

Yes. Phnom Penh's flight operations moved to Phnom Penh Techo International Airport on 9 September 2025, and it is working infrastructure rather than a future project. Individual flight schedules and ground transport arrangements keep changing, so check the route from your particular building again before travelling.

Is the Phnom Penh — Bavet expressway under construction?

Work on the project started in June 2023. We cannot confirm the current percentage of completion or a current opening date: both need to be checked against recent Ministry of Public Works and Transport publications before publishing anything or before a transaction. An originally announced schedule does not count as a current status.

Can you buy next to a future road?

You can consider it, but the price has to survive a scenario in which the project is delayed or changed. Check noise, dust and temporary closures during construction, the actual access and the last mile, land use around the site, and current rental demand without the new road. A future project should be an upside, not the only reason the purchase works.

Does infrastructure guarantee that an apartment will rise in value?

No. A new road or airport can change convenience and traffic flows, but the price of a specific unit depends on title, the volume of competing supply, building quality, actual rent and the entry price. Proximity to a large project can even make living there worse, through noise, traffic and construction.

Does signed financing mean construction has started?

No. The loan agreement for Phase 2 of the Sihanoukville port expansion was finalised on 13 July 2026, while the stated construction start was September 2026. Until physical works or an official notice to proceed are confirmed, the accurate label is 'financing finalised; construction not confirmed', not 'under construction'.
