Continue to see delays while the upgrade is underway
The upgrade and rehabilitation of certain sections of the N4 Toll Route are progressing well

The upgrade and rehabilitation of certain sections of the N4 Toll Route are progressing well and Trans African Concessions (TRAC) is confident that the road works being undertaken will further cement this cross-border route as one of the best highways in Africa.

Expansion and rehabilitation work between the Highveld and OR Tambo Interchanges commenced in April 2017 and comprises expansion of this section into a six lane carriageway.
Road works for this R290-million project are being done in the median, between km 19 and km 31 and will also include the widening of eight bridges, pavement rehabilitation as well as ancillary works such as guardrails and drainage upgrades.

Despite the extensive road works, traffic has not been, and is unlikely to be, severely disrupted as two lanes, with deviations, will be operational throughout the upgrade.
“Road users are however reminded that long-term day closures are currently in place and may result in minor delays,” said Ms Solange Soares-Nicholson, TRAC communications manager.
