The total cost for the construction of Mbudzi interchange flyover is US$88 million with US$65 million being for the interchange structure.
However, the other US$23 million is for works including creation of detour roads, relocation costs, royalties, geo-tech surveys and payment of professional fees.
An internationally accredited firm, DNMZ headquartered in South Africa, is the one that quantified the US$65 million.
To provide context we have provided here a list of some interchanges already built in Africa.
This list, by Leads2 Business, was accurate as of 2023.
