Analyst Notes

The Adamawa Unity Bridge is a major grade interchange, flyover and underpass project constructed at the former Police Roundabout in Jimeta, Yola. The project forms part of the Adamawa State Government's urban renewal programme under Governor Ahmadu Umaru Fintiri.

The project comprises an underpass connecting Galadima Aminu Way with Justice Buba Ardo Road, an overhead bridge linking Atiku Abubakar Road with Lamido Aliyu Mustafa Road, and a ground-level traffic distribution system serving the surrounding roads. The completed infrastructure replaced the former Police Roundabout with a multi-level traffic interchange designed to improve connectivity and reduce traffic conflicts in the area.
