The R21 is a major north–south

R24 near the airport, the N12 and N17 in Boksburg, and the N3 near Vosloorus on the East Rand, where it ends. The section from the N12 to the N3 is not a freeway.[2] The R21 is also designated as the P157.[1]

The R21 is the lowest "R" designated route number in South Africa.[2] The portion of the R21 where it exists as a freeway, from the M10 Solomon Mahlangu Drive off-ramp in Pretoria to the N12 Freeway in the East Rand was declared a National Road in 2008, as part of the Gauteng Freeway Improvement Project,[4] when it was also transferred to the South African National Roads Agency.[4] The improvement project increased the number of lanes (previously, the freeway portion had been a dual carriageway freeway, with 2 lanes in each direction, from the Rietfontein Interchange to Pretoria), and installed lighting along the length of the freeway section.

As a result of the Gauteng Freeway Improvement Project, the freeway section of the R21 was effectively declared as an e-toll highway (with open road tolling) from 3 December 2013 onwards.[5] The South African government announced on 28 March 2024[6] that e-tolls in Gauteng would officially be shut down on 11 April 2024 at midnight,[7][8] therefore returning the R21 to being a toll-free route.

Route

The R21 begins just north-east of

Centurion to its west.[2]

Just after Solomon Mahlangu Drive, near the suburb of

Pretoria Eastern Bypass), which is the freeway between Johannesburg and Polokwane. The Interchange is named the Flying Saucer Interchange. After the N1 Interchange, the R21 freeway continues southwards and has 10 off-ramps and interchanges for the remaining 43 km length of its freeway section.[2]

The R21 intersects with the

M41 (Jet Park Off-ramp) and N12 (Rietfontein Interchange).[2]

After the M31 Irene off-ramp, the R21 leaves the

Tembisa (forms its eastern boundary).[2]

At the

Kempton Park Central, the R21 meets the R24 freeway, which connects the airport with Johannesburg Central in the west. Via the R24 (named the Albertina Sisulu Freeway), the R21 is the only freeway apart from the Ben Schoeman Freeway (designated as the N1) that links Pretoria with Johannesburg.[2]

North of

M41 again and continues by way of a right turn at Rondebult Road. The R21 then meets the R29 (Cason Road) and continues south, bypassing Boksburg Central to the west.[2]

After Boksburg Central, the R21 crosses the

M43 road (Barry Marais Road) for the second time at a t-junction in Dawn Park.[2]

The R21 and the M43 are co-signed south-west. As Bierman Road, the R21/M43 pass over the M35 road (Germiston-Heidelberg Road), intersect with the R103, and reach an intersection with the N3 freeway just east of Vosloorus, which marks the end of the R21.[2]

Albertina Sisulu Freeway

As the

Centurion and Pretoria.[9][10][11] It indicates that the R21 from Pretoria to the airport and the R24 from there to Bedfordview are together known as the Albertina Sisulu Freeway. Together, the R21 and the R24 are the only freeway link between Pretoria and Johannesburg apart from the Ben Schoeman Freeway
.

The naming of the R24 highway from Bedfordview eastwards, together with the R21 freeway from OR Tambo International Airport northwards to Pretoria as the Albertina Sisulu Freeway was completed by the time of the 2010 FIFA World Cup.[12]
