Windhoek Airport freeway, Phase 2A

The construction of the freeway between Windhoek and the Hosea Kutako International Airport had been earmarked since the mid-seventies. A route determination study was done in 1971, followed with a Basic Design and Report in 1978, the latter which still today forms the basis for the detail design of this freeway.

‍

The project is sub-divided into 3 phases (Phases 1, 2A and 2B) because of the urgency Government has attached to the project,

The project is situated along Trunk Road 9 Section 1 between Windhoek and Hosea Kutako International Airport. It forms part of the third phase of the construction of Trunk Road 9 Section 1 to freeway standards.
