The new east-to-north directional flyover at the Gillooly’s interchange, which was one of the highest-visibility and most technical projects within the larger R20-billion Gauteng Freeway Improvement Project, was opened to traffic on Tuesday, June 1, 2010.

The development, which affects OR Tambo International Airport-related traffic, had, thus, been completed in time for the start of the 2010 FIFA World Cup, which kicks off on June 11 and will continue until July 11.

The South African National Roads Agency Limited (Sanral) said that the 250-m ramp offered road users – travelling from Emalahleni (Witbank) in the direction of the Buccleuch interchange – a dedicated facility that would improve the traffic flow on the N12.

But Sanral also cautioned that the incrementally launched bridge had changed the layout and functioning of the interchange, and urged road users to reduce their speed to 60 km/h while on the ramp so as to familiarise themselves with the changes.

The 10-km Gilloolys-to-R21 work package was awarded to the CMC joint venture (JV) in May 2008. The construction JV included CMC di Ravenna, of Italy, and G4 Civils and the package was reportedly valued at €110-million.

CMC is currently involved in projects worth about €700-million in South Africa, including: Eskom’s 1340-MW Ingula pumped-storage scheme, in the Drakensberg mountains; the €20-million N4 Northern Ring Road between Friedenheim and Crocodile Valley in Mpumalanga province; and the Gillooly’s interchange project, in Gauteng province.

The consulting engineers on the Gillooly’s project included a JV comprising Goba and SSI.  Posted in ENGINEERING NEWS.
