text: They are currently constructing a pedestrian & bicycle road parallel to the Grayston drive.
  The construction started on March 4th, 2015. More information and picture can be found on eprop dot co dot za. Or search for Construction of R130m Alex-Sandton bridge.
  The bridge will be constructed North of Grayston drive. At the location of my note, the bridge will make a circle up ramp.
