RFA Chief Executive Officer Stewart Malaya told Parliamentary Committee on Commissions, Statutory Corporations and State Enterprises that visited the site on Wednesday to appreciate progress.
"We expect the Chingeni tollplaza to realise about 4.5 billion Kwacha annually thereby increasing revenue towards roads fund," said Malaya.
He says Covid 19 pandemic has contributed to the delay in completion as some materials have not yet arrived due to travel restrictions world over.
Chairperson for the Committee, Isaac Kaneka, says they will keep on monitoring progress and ensure that funds realized should go towards road maintenance and upgrading.
"We are impressed with the physical progress reportedly at about 50 percent and the reasons for missing deadline seem valid," says Kaneka.
RFA currently relies on fuel levy which contributes about 85 percent of its income.
