THANK YOU! I just saw the video you filmed of this route 8 years before this one, and now I understand why your videos and others of the same time period showed the number of lanes in the Southbound tunnel change from two to one, forcing everyone into the Ohashi junction. The Southbound portion of the C2 tunnel was still under construction at that time! I was very confused for a while! I thought there was an extra Southbound tunnel that threw everyone into the junction! 😁
