Road Lwambo Mitwaba-Manono, the works have passed the city of Mitwaba

On the road Lwambo-Mitwaba-Manono, work is now done after the city of Mitwaba. The firm CCECC has widened the road in the first escarpments that adjoin the Kalume-Ngongo bridge. The ideal is to reach a width that allows the overtaking of two vehicles estimated the Director General of the ACGT visiting this axis. The same operation will be made a few tens of kilometers away in the Milumbi Mountains. In order to achieve a good width on this part of the road, blasting is planned. The studies done by the contractor on the subject informs that the 3 kilometers traveled by truckers in these escarpments of the Milumbi Mountains will disappear to give way to a section of 150 m of road barely.
On the route of this road in its stretch from Kyalwe to Mitwaba, the old metal bridges type Bellay are replaced by permanent bridges in reinforced concrete. The Muvule and Munkana bridges have already been completed. Currently work is done at Kyalwe bridge and Mumbolo. As for the pavement works, they have exceeded the city of Mitwaba by 15 km. The company CCECC has in the visor the city of Manono that it will reach by the end of the season of the works for the year 2019. To arrive there, a strong mobilization of the rolling stock was noted. The DGE traded with the entrepreneur on his return to Lubumbashi so that he has material means; the staff is treated with dignity for the success of this project.
