The port of Puerto Cortes, located on the northeast coast on the Caribbean, is Honduras' main port and is also the largest and deepest port in Central America.
The IDB will help finance the dredging of both habour and port berths.
In addition, the port expansion will also see the development of a new container terminal as well as the improvement of port operations.
Puerto Cortes moves approximately 90% of maritime traffic in Honduras and handles large exports and imports of grain, fertilizers, and other essential goods vital to the Honduran economy, according to the IDB.
IDB says they will be funding 60% of the total project cost.
