Island Loop Tunnel 2 is a very short tunnel compared to Island Loop Tunnel 1. It is probably man-made at the fact it was made out of rocks. You can access this place in the 1st and 4th stages of the Cycling road race and Island Flyover. You have to pay attention to where you are going to find it.
Island Flyover Information:
- Daytime: “The main road around Wuhu Island goes through this tunnel.”
- Evening: “Watch out for traffic!”
- Night: “Slow down!”
