• Base layer of selected lateritic gravel, 20 cm thick
• 25 cm thick foundation layer of selected lateritic gravel
• 25 cm thick foundation layer of lateritic gravel
• 68 culverts in various dimensions (6 x 3 x 1.5 m, 4 x 1.5 x 1.5 m, 3 x 1.5 x 1.5 m, 2 x 1.5 x 1.5 m, 2 x 1 x 1 m and 1 x 1 m)
• Concrete drainage systems
• Road furniture (road markings, signs, guardrails, curbs, etc.).
The project is composed of three sections as follows:
