Traffic chaos is coming to Joburg – here’s what you need to know

The City of Joburg through the Johannesburg Roads Agency (JRA) – its roads and storm water infrastructure development and maintenance entity – is about to start phase 2 of its M1 Rehabilitation project, and is warning road users that they’re in for some traffic chaos.

The JRA has urged road users to find alternative routes and to use public transport to ease traffic congestion in the coming months.

Work on the iconic double decker section of the M1 – between Carr and Anderson streets – will include rehabilitation and structural repairs, asphalt surfacing, expansion joints, drainage systems and new road signs.

The Federation and Oxford bridges will also undergo a major facelift, the JRA said.

A 2km section of dual carriageway between Rockridge and Federation Roads is being rehabilitated. The projects will cost R120-million and R90-million respectively.

“Although the construction will cause disruptions to traffic and delays, it will lead to significant long-term improvements to the City’s freeway network,” the City of Joburg said.

During the construction period certain changes will be made to:

  • The northbound carriageway – carrying traffic from Soweto and the M2 – will be reduced to two lanes between the St Andrews and Killarney off-ramps from 29 February 2016 to 31 December 2016;
  • The southbound carriageway – carrying traffic from Midrand – will be reduced to two lanes between the Killarney and St Andrews off-ramps from 3 April 2016 to 31 December 2016;
  • The southern on-ramp from Oxford Road will be closed at Ettrick Road from 3 April 2016;
  • The northbound Oxford Road off-ramp to be closed from 13 August 2016;
  • Certain lanes on the double decker section will be closed until 6 July 2017 during weekdays between 9.30am-2.30pm. The construction will be halted during morning and afternoon peak hours and stepped up in the evenings and over weekends.

The JRA provided the following breakdown for the different phases:

Oxford and Federation

Phase 2: 27 February 2016 to 12 August 2016, two stage implementation phase:
