City authorities announced the building of an underground pedestrian walkway system to be completed in 45 days as part of Corridor Development projects, causing temporary pedestrian and vehicle detours. Megenagna is one of the most highly congested areas in Addis Abeba featuring the confluence of seven main roads—including the latest connecting Chaka satellite city project.
