National Council MPs want heavy truck tolls on national roads raised, with the proceeds going toward road maintenance.

They made a contribution to the debate on the Road Fund Administration Bill on Tuesday.

In support of the bill, Kabbe South Councilor John Likando is one of the MPs calling for increased charges.

Likando complained that heavy trucks loading and unloading goods at coastal harbors via the Trans-Kalahari and Trans-Zambezi highways were causing significant damage to local roads while paying lower fees.
