I don't think they built many parking spaces for RBC Dexia. This street misses the Gardiner on-ramp that Bay and York drivers use and only has access to the Spadina ramp via Bremner which puts people in the same jam they would be in if they took Front to Spadina. Northward connections are complicated by Simcoe being one-way, closed north of Queen, and the need to make left turns. The benefits of this link seem more local in scale. The Porter bus will probably use it, people going go the south convention centre entrance or CN Tower perhaps, but the fact Simcoe is one-way and closed north of Queen and has no access to ramps means its utility is limited. I would expect to see less traffic through this tunnel than on the Blue Jays Way bridge.
