Talk:Riverside Tunnel

A couple questions: why does a tunnel have a traffic signal and if there's a sign prohibiting "camper gas"(propane) from being brought in the tunnel, why are there several propane tanks around the tunnel usually? Also, if there's a sign prohibiting hazardous materials, why is there a hazmat tanker carrying "volatile chemicals" that was trying to enter the tunnel, although I suppose they could've "inquired with police at checkpoint."
