OK, I'll answer your query
Directions for those that will use the Gateway
If you are coming from the southside using the Gateway, you need to take the East-West Arterial Road exit off the Gateway.
You then drive down to a roundabout (you need to turn right as if you were heading for the airport).
You will now go under the Gateway and you'll be heading for another roundabout.
Go straight through the roundabout (again as if you were going to the airport)...you should very soon see the DFO on your right hand side (I hope you do, as I've never been to DFO, but have seen it from the car).
Hope this helps,
Cheers,
Karen
