Road Safety and Service Ducts on Beji–Jangara–Wushishi Road
The Beji–Jangara–Wushishi Section III road was delivered with complete road-safety installations and road furniture along its full 76.2 km. ICCO also built in service ducts so future utilities can follow the road without disturbing it.
Key facts
- Road markings: 35,790 m² thermoplastic
- Guardrail: 18,200 m W-beam
- Studs and posts: 8,000 reflective studs, 1,600 edge marker posts
- Signs: 270 including 5 overhead gantries
- Kilometre posts: 77
- HDPE service ducts: 55,000 m including fittings and draw ropes
Road safety installations
| Item | Executed quantity |
|---|---|
| Thermoplastic road markings | 35,790 m² |
| W-beam guardrail | 18,200 m |
| Reflective road studs | 8,000 No. |
| Edge marker posts / delineators | 1,600 No. |
| Traffic signs, incl. 5 gantries | 270 No. |
| Kilometre posts | 77 No. |
How they help road users
Thermoplastic markings are hard-wearing and highly visible, guiding drivers through lanes and along the road edge. Reflective road studs and edge marker posts make the alignment clear at night and in poor weather.
W-beam guardrails protect vehicles at higher-risk locations, such as bridge approaches and high embankments. The 270 traffic signs, including five overhead gantries, give drivers clear direction and warnings.
Kilometre posts mark every kilometre of the route, from km 0 to km 76, helping with navigation, maintenance and emergency response.
Service ducts for the future
The road has 55,000 linear metres of HDPE service ducts, including fittings and draw ropes. This is made up of 50,000 m of longitudinal 2 × 110 mm ducts and 5,000 m of 2 × 160 mm ducts at 125 road crossings.
| Duct type | Length |
|---|---|
| Longitudinal ducts, 2 × 110 mm | 50,000 m |
| Road-crossing ducts, 2 × 160 mm (125 crossings) | 5,000 m |
| Total HDPE service ducts | 55,000 m |
These ducts let telecommunications and other utility lines run along and under the road later. Because the ducts are already in place, the pavement will not need to be cut each time a new service is added.
Certified safe and complete
The Niger State Ministry of Works rated the project's safety performance as Very Good in the Certificate of Completion dated 8 May 2025. The road was taken over on 6 February 2025 and was followed by a 12-month defects notification period.

Frequently asked questions
What road safety features does the road have?
Thermoplastic road markings (35,790 m²), 18,200 m of W-beam guardrail, 8,000 reflective road studs, 1,600 edge marker posts, 270 traffic signs including five gantries, and 77 kilometre posts.
Why are there HDPE ducts under the road?
They let telecommunications and other utility lines run along and under the road later, so the pavement does not need to be cut each time a new service is added.
How much duct was installed?
55,000 m in total: 50,000 m of longitudinal 2 × 110 mm ducts and 5,000 m of 2 × 160 mm ducts at 125 road crossings.
Where are guardrails used?
W-beam guardrails protect vehicles at higher-risk locations, such as bridge approaches and high embankments.
