(ST. JOSEPH, Mo.) Zipper merging is a technique MoDOT wants drivers to start using in work zones.
Instead of merging into the open lane early, MoDOT says drivers should stay in their lanes and get over once they see the sign to merge. MoDOT says the technique is actually keeps traffic flowing faster through workzones.
"It's more benificial because we reduce the impact zone. Instead of having a four mile back-up we have a two mile back-up that doesn't have more interchanges down the road. We also reduce the delay time for travelers getting though that work zone," said Traffic Operations Engineer Adam Wood.
MoDOT says zipper merging has already been heavily implemented in St. Louis and Kansas City with positive results.
