Suddenly new traffic advice comes from MoDOT about how to drive in a construction zone...of which there will be many this summer. The Missouri Department of Transportation is urging us to rethink how we merge into work zone traffic and "merge like a zipper."
My first thought was "what the heck does that mean?" I pictured how an actual zipper works and could not work that into merging onto an interstate. Basically it means taking turns, both the merging car and the car in the driving lane. I think.
"The theory is, instead of trying to get in the lane you want to be in ‘early,’ wait – merge at the last opportunity and each lane takes a turn. That way it doesn’t matter which lane you’re in. Both of them move at the same pace.”
I still can't picture this, but it is what it is. I do know it's tough to merge on many St. Louis interstates, there's isn't much room. 64-40 at Hampton, 170 at Forest Park Parkway, and many more.
