RDA spokesperson Loyce Saili said in an interview yesterday that the K278 billion contract was signed on Friday last week.
Ms Saili said the two year project would also see the rehabilitation of the Lubemba Bridge which is on the road.
She said the upgrading of the road would be from Mokambo border in Mufulira to Chembe Bridge in Luapula Province.
RDA, under the MMD Government awarded a contract to Fratelli Locci at the cost K300 billion to rehabilitate Pedicle Road.
However, the Patriotic Front (PF) Government recently terminated the contract due to flaws in awarding of the contract.
The contract was signed between RDA and Fratelli Locci on August 5, last year at a tender cost of K313, 887,290,717.78.
It was for the upgrading of 70 kilometres of the road through Democratic Republic of Congo (DRC).
The road connects Luapula and Copperbelt provinces in Zambia.
The company was also contracted to construct a reinforced concrete bridge at Lubemba, on the same road.
