The Pedicle Road connects the Copperbelt
Province with the Luapula Province in the
northern part of Zambia. The route crosses the
south-eastern part of the Katanga Province
which is located in the Democratic Republic of
Congo (DRC). The road upgrade portion is
approximately 68kms and starts at the
Zambian/DRC border at Mokambo and ends at
the DRC/Zambian border at Mwenda.
The existing road is a gravel road that is in a very
bad state of disrepair. The cross section of the
existing road (gravel surface) has been eroded
and the road is generally lower than the adjacent
ground. As a result, the road becomes flooded
during periods of heavy rain, becoming
impassable, resulting in the road being closed to
traffic at times.
HHO Africa was appointed by the Zambia Road
Development Agency to carry out the detailed
assessment and design for the upgrade of the
existing road to a bituminous surface standard.
The construction of a new bridge over the
Lubembe River also forms part of the upgrade.
Extensive ponding due to the depressed gradeline and the blockage of drainage culverts|
Existing single lane bridge to be replaced|
Upgrading required at the border crossings|
Construction of the road commenced in March
2012 and is expected to be completed by
Features of the project include :
- Carrying out topographical survey and
- assessment of the existing road
- Carrying out condition assessment of
- bridges and culverts
- Pavement material profiling and sampling
- Materials behaviour assessment
- New alignment and shoulder widening
- Drainage design
- Border crossing upgrades
