From the airport take the R24 exit towards JHB. Eventually the R24 links up with the N12. Remain on this highway, in the three left hand lanes. (The very far left hand lane will eventually head towards Germiston / Alberton although it says Durban/ Bloemfontein and the far right would take you into JHB.) At the Gilloollys interchange take the new N3 Pretoria fly-over. The next off-ramp is Linksfield Rd (M16). Take this off-ramp, and at the traffic lights turn left, back over the freeway. Keep in the far right hand lane. Once over the freeway (just after the traffic lights) turn immediately right into Edward Drive just before the Engen service station. The Conference Centre is on the right hand side just before the road closure.
