Challenges

Geological & Hydrological Issues

Poor Soil Conditions

Soft clay soils in Uyo required soil stabilization (cement treatment) to prevent road failure.

Flooding & Drainage Issues

Inadequate and lack of initial drainage system led to waterlogging, requiring redesign of the whole drainage system and the provision of new undergrounds to drain the stormwater in some sections.

Right-of-Way (ROW) Conflicts

Some property owners resisted demolition without adequate compensation.

Legal disputes slowed progress in certain sections.

Traffic & Logistics Challenges

Heavy Traffic Disruptions: Construction especially between Ibom Plaza and Nwaniba/Oron Road Junction (approx. 1km) was very difficult and affected by heavy traffic and plenty shops along the road.

Material Supply Issues: Occasional delays in granite supply from quarries.

Funding & Project Delays

Intermittent budget releases slowed progress.
