Help with traffic concern!

I am looking for someone to come to my island to help me identify my traffic concern area. I have been working on my island for a few months, so there are several areas that are decorated. I keep running through my most populated areas to find the issue, but I feel that you can get through all of my areas without trouble. So if anyone would be willing to come help me identify the problem, I would greatly appreciate it! I will return the favor by giving bells, nmts, or diys, depending on what you need!
