I'd turn on my signal and merge over as soon as I saw an opening (Or let in). Not jump around everyone, waiting until the last minute. The notice of the road closed ahead is enough to prompt me to move over as soon as safely possible.
This is what causes the problem! Use the road, the whole road. Don't crash through the barricades, and you're good.

If the sign says "lane closed ahead" where is the fault or failure to observe the sign?I tend to be more careful in construction zones because I know that sometimes someone can step out on to the road and you might hit them, or something like a front end loader may pull out unexpectedly into that open area, and because you are zipping around trying to get ahead of everyone else they clip you and eventually you end up being the one at fault because you failed to observe the posted signs. It's not about being right or wrong it's about being safe.
