put a yield sign there during construction and after the construction is finished. nobody stops at the stop sign anyway. the only time they do is when there is traffic coming. and even then i have seen people pull right out in front of cars because they are too darn impatient . replace the stop sign with a yield or station a police officer so maybe more people will remember how to read. stop means stop not yield.

Don't keep stop sign! It causes backups onto 422! Which is far worse!

This is a very poorly thought out suggestion. The point of on-ramps and off-ramps is to merge into traffic. When cars stop before trying to merge, it creates he opportunity for more accidents because a stopped car has to then accelerate to keep up with traffic. And, as everyone else has said, the backup this would create on 422 would have much more impact than that on route 100.

I COMPLETELY DISAGREE with the stop sign idea. It's a bad idea and very conducive to accidents. In fact 422 was designed with an outdated plan that has very short on/off merge ramps. The 422/100 interchange is poor at best with people trying to cross each other as folks merge on while others are trying to get off of 422. A stop sign is NOT the answer at 100. People should yield yet accelerate and get going, not get to the end of the ramp and chicken out like an old lady.

That's a really dumb idea. Yield=yes...stop=no. Merging into traffic on 100 should be a snap if only the 100 drivers would switch to the left lane when possible. It really ticks me off when drivers fail to do so, especially when merging onto 422 with those many short merge lanes; but that's another issue.

It is not the responsibility for drivers already on rt 100 to make unnecessary lane changes to accommodate people who do not understand the concept of YIELD. Drivers on 100 have the right of way. Simple as that.

"It is not the responsibility for drivers already on rt 100 to make unnecessary lane changes to accommodate people who do not understand the concept of YIELD"
While I completely agree that "yield" is poorly understood concept, it is common driving courtesy to switch lanes so people can actually have to opportunity to merge. I know that when I'm driving, I switch to the left lane to accommodate those who are trying to merge onto the highway. Of course the drivers on route 100 have the right of way, but everyone should be aware of their surroundings. If there are people trying to merge and no one is in the left lane, switch lanes. It doesn't take much effort.

Put PA to work. Mandate across PA that at every merging road that encroaches onto another road with a yield sign especially a major highway such as 422 and 100 should have a minimum run on and a minimum run off to accommodate those drivers trying to get on and off the highways. Add another lane to the right just for getting on and off the highways. Here is an idea also, use people that actually live in PA to do the work. duh

Adding a stop sign makes it harder to merge in NOT easier! It will also have an adverse affect on traffic when someone pulls out slower into traffic because they had to stop completely!
