THE MULTINATIONAL NACALA ROAD CORRIDOR PHASE 1 – LILONGWE WEST BY-PASS PROJECT
The Lilongwe Western By-Pass is part of the Nacara Road Corridor. The Nacara Corridor starts from Mozambique at Chiponde and traverses down the escarpment on M03 to Liwonde through Mangochi town. From Liwonde it connects to Lilongwe City on M01 before ending at border with Zambia at Mchinji on M12 .
The Lilongwe City Western By Pass Road is located entirely within the city of Lilongwe and runs from the Kaunda Road Junction off the Lilongwe-Mchinji Road (M12) near the Malawi Revenue Authority Offices to the south west of the city, crossing Likuni Road and the Lilongwe River to join the Lilongwe-Blantyre Road (M1) at the Bunda Turn-off (S124). The total length of the by-pass is 13.4km.
The by-pass traverses largely uninhabited farmland and has been constructed as a Class 1 bitumen standard road with a 7m wide carriageway (with 50mm thick asphalt concrete surfacing) and 2m wide shoulders either side also surfaced by 50mm asphalt concrete in order to accommodate pedestrians and other non-motorized traffic and enhance road safety.
The pavement construction comprises of earthworks, a 300mm subgrade in selected material (CBR > 15%), a 300mm sub-base in approved natural gravel (CBR > 30%) and a 200mm base constructed of graded crushed stone.
Major engineering features along the road include:
- One double span bridge (18m each span) over the Lilongwe River;
- Three triple cell box culverts with each cell 3 meters wide and 3 meters high;
- One single cell box culvert with a cell of 3 meters wide and 3 meters high;
- 900mm diameter concrete pipes at 17 locations;
- Service ducts every 500 meters all along the
The project road forms part of the multinational Nacala Corridor which connects Lusaka in Zambia to Nacala Port in Mozambique and it facilitates the easy movement of goods and people without congesting the city centre of Lilongwe thereby reducing travel times and operating costs. The road also promotes development activities along its corridor.
