PennDOT says it has a plan to improve the traffic flow in and around Wilkes-Barre Scranton international airport and Avoca.
Part of that is the elimination of an exit ramp.
The changes took place overnight on Monday.
Exits 178 A and B in Avoca will be combined in to one. The change affects both the North and South bound lanes.
The ramps that have been here for decades will be replaced by round-a-bouts.
The construction project also involves widening the bridges, and building a road that connects Navy Way to the near by Grimes Industrial Park.
PennDOT thinks that new road will ease truck traffic through this part of Luzerne County.
The $42 million dollar construction project began last summer and is scheduled to wrap up in the fall of 2015.
