Asian Highway Network

The AH project was initiated by the United Nations in 1959 with the aim of promoting the development of international road transport in the region. The highway network would provide for greater trade and social interactions between Asian countries, including personal contacts, project capitalizations, connections of major container terminals with transportation points, and promotion of tourism.

It is one of the three pillars of the Asian Land Transport Infrastructure Development – ALTID project, endorsed by The United Nations Economic and Social Commission for Asia and the Pacific – UNESCAP commission at its 48th session in 1992, comprising Asian Highway – AH, Trans-Asian Railway – TAR and facilitation of land transport projects.

In 2003, 55 AH routes among 32 member countries were identified and Intergovernmental Agreement on the Asian Highway Network – IGA was adopted and signed by 23 counties during the 60th session of the UNESCAP Commission at Shanghai the following year.
