Taraba to construct mambilla power plant road

I think there may be a small mistake in your question. Taraba is a state in Nigeria, and Mambilla is a plateau in Taraba State. Therefore, it's unlikely that Taraba State will construct a road to the Mambilla Power Plant, as the power plant is already located on the Mambilla Plateau.

However, I assume you meant to ask about the construction of a road to the Mambilla Power Plant, which is a proposed hydroelectric power plant located on the Mambilla Plateau in Taraba State. If that's the case, here's what I found:

The Mambilla Power Plant is a major infrastructure project in Nigeria, aimed at increasing the country's power generation capacity. The project involves the construction of a 3,050 megawatts hydroelectric power plant on the Mambilla Plateau, which is expected to be one of the largest power plants in West Africa.

As part of the project, a road is being constructed to connect the power plant to the nearest town, Serti, and then to the national grid. The road is expected to be a critical infrastructure for the project, as it will facilitate the transportation of equipment, materials, and personnel to the construction site.

The construction of the road is being undertaken by the Nigerian government, in collaboration with the Chinese government, which is providing financial and technical assistance for the project. The road is expected to be completed in the next few years, along with the rest of the power plant project.

I hope this answers your question!
