It doesn't though. It's mostly between 4-530.
When I leave work at 5, the parking garage is 90% empty. Most have already left before 5.
To be fair, those days exist with oc transpo too. Funny story. My buddy who takes the bus appeared on the front page of the newspaper TWICE in a few months looking all pissed off in a crowd of 100s of people waiting for buses to replace the rail that wasn't working.
The hope would be that those lights could be green for the most part at this time of the night.
Also part of what makes gridlock is that the cars leaving, are blocked by cars ahead...but the rest of the area will be empty, so nothing will be slowing down the first cars out like a normal day of commuting does. Should allow for more flow. Normally, even if you're beating the rush out of the downtown core towards the highway, the highway is already bumper to bumper from people getting on from all over the city, which makes things stop to a crawl. Those feeder streets to the highway are stopped because they can't get on the highway fast enough because it's blocked. This wouldn't be the case after a sens game. Once you get on the highway, it should be fast flowing with nothing ahead blocking you. The amount of people would only be like 10% of what a normal commute looks like. Will be breeze. You might have congestion the first few blocks around the arena, but that's why if you're smart, you'll park a few blocks away and can briskly walk/jog to your car and get in where traffic is thinner and then get on the highway and fly to your suburb because 10pm traffic is non existent in the Ottawa core most nights lol
