Traffic around Nationwide Arena?

Nationwide Arena is a venue in or near Columbus that is most often used for Hockey

This is one of the best venues I have ever been to where the traffic cops do such a good job of getting people out of the stadium.

after an event, there would be traffic mainly on Nationwide Blvd and Front Street from guests coming out of 2 garages, but cops and security do a nice job keep the traffic slowly moving.
