Grupo Argos' concessions subsidiary, Odinsa, has proposed to invest in two airport development projects in Colombia.

The first involves the expansion of Bogotá's primary international gateway, El Dorado airport. Grupo Argos owns a 65% controlling stake in the airport's concessionaire, responsible for its administration, operation, commercial exploitation, maintenance, modernization and expansion. Works proposed include the addition of a third runway and new passenger terminal.

Odinsa plans to invest US$3.2 billion in the project. The expansion would increase the terminal surface area from 240,000 to 400,000 square meters and the number of parking positions from 89 to 170.

The company is also proposing to construct a new airport terminal in Cartagena, a major port city and capital of Bolívar state located in the north. Odinsa has identified a 654-hectare site for the terminal, which will span 70,300 square meters.

If approved by the National Infrastructure Agency (ANI), the project would begin construction next year, with the new terminal to open in 2026. Odinsa predicts that the terminal would handle 11 million passengers in its first year of operations.
