Rehabilitation / Improvement, Routine Maintenance Works of N220 Chissano - Chibuto and N/C Crz. N220 - N1 (3 De Fevererio)
The project consists of the Rehabilitation/Improvement, Routine Maintenance Works of N220 Chissano – Chibuto and N/C Crz. N220 – N1 (3 De Fevererio) located in the Gaza Province in Mozambique. The two roads fall within the Limpopo floodplain and have been damaged by recent floods, with sections of the roads washed away.
The scope of works includes the reconstruction and/or rehabilitation of 57 km of road including the construction of 52 box culvert structures, varying in size from 2 m x 1 m box culverts to 5 m x 3 m box culverts.
An existing bridge at km 20.5 of Road N220 has undergone severe erosion of the embankments, which has led to the collapse of the bridge approaches. Moreover, the existing bridge piers built on shallow foundations were also noted to show major signs of settlements which contribute to the structure being unsafe and unserviceable. The project scope includes the construction of a new 80m bridge to replace this existing along Road N220.
