The Limited Rehabilitation of the 83.83 km Saki-Iseyin Road

An update and pictures of the limited rehabilitation of the 83.83 km Saki-Iseyin Road, a federal road in Oke Ogun Zone, by the Oyo State Government. The limited road rehabilitation commenced this month, December 2024, and is being executed by Kopek Construction Limited. The promise to rehabilitate the Saki-Iseyin Road was made by Governor Seyi Makinde on 20 June 2020 during the flagging off of the reconstruction of the Oyo State Agribusiness Development Agency (OYSADA) Headquarters in Saki.

The rehabilitation of the Saki-Iseyin Road includes a series of essential activities designed to improve its structural integrity and ensure its durability. The activities are listed below:

• Clearing: This involves removing vegetation, debris, and other obstructions along the road path, preparing the site for construction by creating a clean and open area to work effectively.

• Scarification: This process involves breaking up and loosening the existing road surface. This removes any damaged or worn-out material, creating a base suitable for rebuilding or resurfacing the road.

• Earthworks: This includes excavating, moving, and reshaping the soil to create a stable foundation for the road. Earthworks also involve filling low-lying areas and levelling the ground for proper drainage and road stability.

• Retaining Walls: This involves building structures to hold back soil or prevent erosion, particularly on slopes. Retaining walls ensure the road’s stability and protect surrounding areas from landslides or soil collapse.

• Lateritic Subbase: A layer of laterite (soil rich in iron and aluminium) is spread and compacted to provide a strong and stable foundation beneath the road’s surface. This layer absorbs vehicle loads and distributes them evenly.

• Crushed Stone Base Course: A layer of crushed stones is added to the subbase. This layer enhances the road’s strength, provides a firm surface for the upper layers, and ensures durability under heavy traffic.

• Wearing Course: This is the topmost layer of the road, often made of asphalt. It provides a smooth driving surface, protects the underlying layers, and ensures the road’s durability against weather and traffic wear.

The entire 83.83 km of the Saki-Iseyin Road project is expected to be completed within three months. Once completed, the 83.83 km Saki-Iseyin Road will offer improved accessibility, enhanced durability, and better driving conditions for residents and commuters.

Governor Seyi Makinde, during the commissioning of the dualised 12.5 km Challenge-Odo Ona Elewe-Elebu-Apata Road in Ibadan, said where roads go, development follows. Other federal roads fixed by the OYSG include the 65 km Moniya-Iseyin Road, the 34.85 km Oyo-Iseyin Road and the 35.3 km Ibadan-Iwo-Osogbo Road among others.
