The gas tax money has been a great success story in terms of investment in local infrastructure. I think the municipalities have been using their gas tax money for a variety of different purposes; part of it has been going to transit, part of it to roads, and part of it to other infrastructure needs.
In the City of Toronto, they have directed their gas tax money largely to transit. As to whether it goes specifically to a cross-town project or they put it into other transit projects that the Toronto Transit Commission is pursuing, I don't have that level of detail about how they disburse the funds.
