Two more states hop on board with the ‘zipper merge’
KANSAS CITY, Mo. — Transportation officials in Missouri and Kansas are encouraging motorists to resist the urge to get in line at the first sign of an upcoming lane closure.

They say it doesn't get drivers through the zone any faster, but it reduces the risk of accidents and eases driver angst.
