The Nasarawa urban roads project was delivered with full road safety features, road furniture and street lighting along all 75 km. These works were planned during design, which included dedicated road-safety and lighting designs for the corridor. The result is a six-lane road that is lit, marked and signed from end to end, with separate space for people on foot.
Key facts
- Lighting poles: 939, 12 m high, double-arm
- LED luminaires: 1,878 at 180 W each
- Road markings: 600,000 m of thermoplastic edge and lane lines
- Road studs: 50,000 retro-reflective studs
- Guardrail: 9,000 m galvanised W-beam
- Pedestrians: 45,000 m² walkways and 2 steel footbridges
Street lighting
ICCO installed 939 street lighting poles, each 12 m high with double arms. These carry 1,878 LED luminaires rated at 180 W, two on every pole. Spread along the 75 km corridor, that works out at roughly one pole every 80 m on average.
Good lighting helps drivers see the road ahead, spot pedestrians and judge distances after dark. LED luminaires also use less energy than older lamp types, which helps keep running costs down. They also tend to last longer between replacements, which reduces maintenance visits on a busy road.
Keeping vehicles on course
Road safety works across the corridor included:
| Item | Executed quantity |
|---|---|
| Thermoplastic road markings – continuous edge lines | 300,000 m |
| Thermoplastic road markings – broken lane lines | 300,000 m |
| Precast concrete median kerbs | 150,000 m |
| Retro-reflective road studs | 50,000 Nos. |
| Galvanised W-beam guardrail incl. terminals | 9,000 m |
| Regulatory, warning and information signs | 600 Nos. |
On a six-lane road, clear lane and edge markings guide drivers through each lane. The 300,000 m of edge lines and 300,000 m of lane lines are each equivalent to four lines running the full 75 km. Thermoplastic markings are applied hot and bond to the asphalt, so they last longer than ordinary road paint.
Reflective studs make those lines visible at night and in rain, while guardrails protect vehicles at higher-risk locations such as embankments and bridge approaches.
Signs and road furniture
Six hundred regulatory, warning and information signs tell drivers the rules of the road, warn them of hazards ahead and help them find their way. Precast concrete median kerbs, 150,000 m in all, define the central median that separates the two directions of travel.
Space for pedestrians
The project also considered people on foot. ICCO laid 45,000 m² of concrete walkways in urban sections, giving pedestrians a separate path away from traffic. Two steel pedestrian footbridges were also built, allowing people to cross the wide carriageway safely.
On a road with six lanes of traffic, crossing at street level can be hazardous, especially for children and older people. Footbridges and walkways keep pedestrians apart from vehicles where traffic is heaviest.
Certified complete
The employer certified the works complete on 27 June 2026. The Certificate of Completion states that ICCO complied with the applicable contractual, technical, environmental, social, health and safety requirements throughout the works.
