The South African state-owned power utility, Eskom, has advised that on Sunday, 13 August 2017, there will be temporary road closures at the Flying Saucer interchange and Olifantsfontein Drive on the R21 freeway.
The temporary road closure – between 5am and 6pm – is primarily aimed at the stringing of conductors over the R21 after the approval from SANRAL to close the freeway between the advised times.
The parastatal explained in a statement that the Apollo-Croydon 275 kV transmission line tripped in the early hours of Friday 19 May after a truck hit one of the towers causing the line conductor to come down between Nellmapius and Olifantsfontein Drive on the R21 highway between Johannesburg and Pretoria.
Motorists are advised to use the following alternative routes: Botha Avenue, Olifantsfontein, N1, N3, Rigel Avenue and Delmas Road.
Apollo-Croydon transmission line
The Apollo-Croydon line is planned to be commissioned on 16 August 2017, the utility said.
Adding that the construction work began on 9 June 2017, after a suitable contractor was identified, inducted and designs finalised.
The Apollo-Croydon 275 kV supplies the Croydon substation with Croydon-Jupiter 275 kV as a back-up. The substation was rendered unstable with Apollo-Croydon line out.
The following customers are currently at risk of interruption in the event of loss of the remaining Croydon- Jupiter 275 kV line, namely:
- Ekurhuleni Metropolitan Municipality which supply Kempton Park, Germiston, Bedfordview, and Edenvale Central Business Districts (CBDs) and the associated industries and suburbs;
- City Power at Modderfontein including the associated industries and suburbs
- ACSA (OR Tambo International Airport)
Eskom would like to appeal for restraint, co-operation, collaboration and patience when this line is strengthened for the long term mutual benefit of all road users and stakeholders.
