"Use Both Lanes to Merge Point" on US-34/75
Since November 5, motorists traveling on US-34/75 in the area of the Plattsmouth to Bellevue North construction project have seen a series of signs asking them to "Use Both Lanes to Merge." This process is known as a "late or zipper merge" and is used when traffic is reduced from two lanes to a single lane according to the Nebraska Department of Roads.
A "late or zipper merge" occurs when motorists use both lanes of traffic until reaching the defined merge area, and then alternate in "zipper" fashion into the open lane. This type of merge works best for situations where reoccurring backups are expected. This merge will be required from November 2016 until spring 2019 while lanes and bridges are rebuilt on US-34/75.
