Sanral would start delivering its submissions, in Pretoria, from Tuesday to Thursday, spokesman Thabo Masebe in a statement.
Makhura established the review panel to examine the economic and social impact of the Gauteng Freeway Improvement Project and the electronic tolling system set up to fund it.
The panel has received numerous submissions from the public, various non-governmental organisations and political parties.
The e-tolling system has been largely rejected, with many calling for it to be scrapped.
The panel was expected to present its findings to Makhura at the end of November.
