In particular the closure will affect those linking to the M2 from the M1 to drive into central areas of the city such as the Gandhi Square Precinct and Maboneng and those travelling to these neighbourhoods from OR Tambo International Airport via the M2.
The closed section of the M2 includes the following junctions:
2. M1 approaching from the south, ramp onto the M2 eastbound
3. M1 approaching from the north, ramp onto the M2 eastbound
4.. Booysens Road on-ramp onto the M2 westbound
5. Simmonds Street on-ramp onto the M2 eastbound
6. Eloff Street on-ramp onto the M2 eastbound
7. Eloff Street on-ramp onto the M2 westbound
8. Wemmer Pan Road on-ramp onto the M2 westbound
9. Heidelberg Road on-ramp onto the M2 westbound from the south and the north
10. Heidelberg Road on-ramp onto the M2 eastbound from the north
Travelling into the city
If you were planning to use the M2 exits along this closed section of road such as Mooi Street, Eloff Street, Rissik Street or Joe Slovo Drive, to access the Joburg inner city, you do still have plenty of options if you are coming from the north via the M1, although increased traffic may mean delays.
Eastern downtown areas such as the 1 Fox Precinct, Ferreirasdorp and the Main Street Mining District are unaffected by the road closures as these areas are accessed via the Village Road exit. You can also use the Village Road exit to continue travelling east, parallel to the motorway, to reach the main central downtown thoroughfares of Mooi, Eloff and Rissik Streets.
A popular access route into Maboneng from northern Joburg is via the M2 Joe Slovo ramp which will be closed. An alternative route is to follow Joe Slovo Drive all the way from where it connects with the M1 at Killarney in the north. Alternatively, to reach Joe Slove Drive from the M1, you will need to take a right onto Marshall Street from Village Road and travel several blocks.
Travelling to the airport
If you are travelling to the airport from areas to the east such as Soweto or Gold Reef City, take the N12 southern bypass instead of the usual M2 route. Those travelling from Maboneng can make easy use of Albertina Sisulu Road or connect to the M2 highway a little further west via the R29.
