    I grew up in Port Huron and always thought the tunnel was near Tunnel Street. Finally 40 years later I returned to Port Huron for a visit and was bound to find the Tunnel. Makes sense it is found near the Amtrac station. Interesting historical marker says that there was a plot during WWI to blow it up. I will attach photos when TA makes it possible. See more..
