Not only I 78 but I 80 and I 81 are still closed.
From reading news reports, you would think that I-78 was the only road affected. These Philly reporters need to realize that there was just as much, if not more of an impact on I-80 and I-81 being closed.
I live 4 miles from the one exit that was closed (Berwick/Lime Ridge), and with the closure, Route 11 effectively became Interstate 80 for the past several days. It paralyzed the town, as it was bumper to bumper traffic at a snail's pace for MILES. I've seen storms that were worse, and yet we never had problems like this.
