TRIPP Corridor Construction to Begin in Late 2026, Pashinyan Confirms

Construction of the TRIPP corridor — a flagship U.S.-backed infrastructure project connecting Armenia and Azerbaijan via a new railway, natural gas pipeline, and power transmission line — is expected to begin in the second half of 2026, Prime Minister Nikol Pashinyan confirmed this week. The announcement follows months of detailed engineering and legal work and represents the most significant physical manifestation yet of the 2025 White House-brokered peace deal between the two countries.

The corridor, whose name stands for Trump Route for International Peace and Prosperity, traces a 42-kilometre alignment through southern Armenia — the Armenian section of the broader Zangezur connectivity scheme. Under the trilateral framework agreed at the White House on 8 August 2025, the United States was granted exclusive rights to develop and operate this segment, an unusual arrangement that reflects Washington's commitment to underpinning the peace agreement with tangible economic infrastructure.

Pashinyan told MPs that the technical and operational parameters for the TRIPP configuration are expected to be finalised during the first half of 2026, with construction to follow shortly after. He described the project as transformative for Armenia's economic geography, noting that it will "ultimately allow the Republic of Armenia to fully emerge from its state of blockade" — a reference to the landlocked country's historically constrained access to regional markets.

The infrastructure package encompasses a new railway following an existing but decommissioned Soviet-era alignment, a natural gas pipeline providing Azerbaijan with an alternative southern export route, fibre-optic cables, and electricity transmission lines. Analysts at the Carnegie Endowment for International Peace have described TRIPP as potentially rewiring the entire South Caucasus connectivity architecture, integrating the region into the broader Middle Corridor trade route linking China and Central Asia to Europe.

Azerbaijan's section of the corresponding Zangezur infrastructure project is reported to be nearly complete, meaning that once Armenia's segment is built, a continuous physical link will exist between the Caspian Sea and Turkey for the first time in decades. This would benefit Azerbaijan by providing a direct overland route to its exclave of Nakhchivan without dependence on Iranian or Georgian territory.

The project has attracted attention from major international financing institutions. The Asian Development Bank and the European Bank for Reconstruction and Development are understood to be in advanced discussions about co-financing the Armenian section, while Gulf sovereign funds have expressed interest in equity stakes in the operational entity.

Not everyone is enthusiastic. Iran has expressed concern that the corridor could reduce its transit role, while some Armenian opposition figures have questioned the legal terms under which the United States was granted development rights. Pashinyan's government has defended the arrangement as necessary to attract the security guarantees and financing that a project of this sensitivity requires.
