Driving home takes such a long time. I have, though, discovered construction zones which cause traffic jams, and side roads that I can take to avoid them. I'm always hesitant as to whether to take these roads, because there's always a chance that there will not be a traffic jam. However, ever since I got caught in an hour long traffic jam on I-78 approaching I-81, I have often taken these alternate roads. It involves taking US 22 between I-81 and I-78, and then taking exit 40 on I-78 down to a small state road that parallels I-78, and I then take that east all the way into Allentown.
The other thing that Pennsylvania does is ask that you use both lanes to the merge point. In other states, they tell you well in advance which lane is closed so that you have time to move over. They do not do this in Pennsylvania. In fact, often, to make sure that you use both lanes to the merge point, they keep which lane is closed a surprise until you actually get to the merge point. On the one hand I think this is good, since it maximizes use of the road to the merge point. However, I still wonder if it does anything, because if you have cars merging in gradually as you approach the lane closure, as opposed to one exact point, wouldn't it work better, since the effect of the lane closure would not be as concentrated?
Of course, if they did not have one of those signs instructing people to use both lanes, and someone tried to merge in at the merge point, I probably would not let them in, because they would be cutting the line. I imagine if this idea of using both lanes was so good, other states would use it, and I have not seen this outside of Pennsylvania, so maybe it is not such a good idea.
