City of Port Adelaide Enfield has explained to me that both they and Department of Infrastructure and Transport will not support this location as it's:

1. "A safety issue" (even with fencing and the current bollard);
2. Difficult "for maintenance" (even though there are lights installed there that will need to be fixed); and
3. A distraction to drivers (even though many facilities are already built on main roads).

However they are interested in exploring under Hart Street Bridge, New Port: https://goo.gl/maps/KWe1qQyNpgrgKZps6

I am meeting with them next Friday to discuss.
