Lake Shore, the QEW, The Queensway, Dundas, Bloor, Burnhamthorpe, and Eglinton all cross the Etobicoke Creek south of the 401.
Until Hurricane Hazel, Mill Road also crossed the creek, and joined up with what is now called Southcreek. Sherway Drive, between the QEW and The Queensway, has a bridge, but it has only open to pedestrians for a few decades now.
To add another bridge over the Etobicoke Creek, one has to convince two municipalities that it would be a good thing to spend the money. Mississauga has wanted a Rathburn bridge since the neighbourhood went in on the west side of the creek up there, but neither Etobicoke nor Metro (and now Toronto) was ever interested in spending the money to connect there. In this North Queen case I don't think you'd have buy-in from Mississauga. Why would that city want to make it easier for its residents to drive to Toronto to spend their money?
