Honduras' public works, transport and housing ministry (Soptravi) has completed feasibility studies to build a highway connecting the Palmerola military base in Comayagua municipality with capital Tegucigalpa.
The project falls under the government's plans to build an international terminal where the military airport is currently located, 70km north of the capital, according to a presidential release.
The Singapore Cooperation Enterprise (SCE) recently signed an MOU with Soptravi to help finance the planning and construction of the new international terminal.
The government recently reached an agreement with local concessionaire InterAirports to build and operate the terminal. The company has said it has US$100mn available to complete construction.
Palmerola is a US-controlled military base that will share facilities with InterAirports, which has operated the country's four international terminals since 2000.
The military base was chosen as the site for the country's new international passenger terminal after the government shut down Tegucigalpa's Toncontín airport in May 2008, following an accident that left five dead.
