The R200-million project to rehabilitate 7km of the N2 between Borcherds Quarry Road and the R300, is nearing completion.
The project, which includes a third lane being added in both directions, is expected to be completed at the end of November.
New street lighting has also been installed.
The construction of the final riding surface to improve drainage and skid resistance has started and will take about three weeks to complete.
New lane markings will then be painted and final road signage installed.
Traffic will continue to be restricted to two lanes on both the inbound and outbound roadway.
Lane restrictions have been necessary to complete the median barrier, street lighting and preparation for the final road layer. Motorists are encouraged to exercise caution and adhere to the speed limit at all times.
The carrying capacity of the road will be improved with an extra lane on each side.
This will benefit high-capacity buses and taxis in particular because the right hand lane is designated as a dedicated bus lane during peak periods.
The provincial Department of Transport and Public Works said many people have benefited from short-term employment and skills training that the project has delivered with a total of 21 619 person-days of work having been created for residents.
