MnDOT: Zipper Merge in Minnesota

Posted by Content Coordinator on Thursday, September 6th, 2012

Most Minnesota motorists start to merge in construction zones as soon as they see warning signs and learn which lane ahead is closed. This driving behavior, called “early merge” can lead to dangerous lane switching, inconsistent driving speeds that cause crashes, long back-ups that block interchanges, and road rage.

Research shows, however, that these dangers decrease and traffic moves more smoothly when motorists use both lanes until reaching the defined merge area and then alternate in “zipper” fashion into the open lane.
