There's construction everywhere at the Minneapolis-St. Paul International Airport — both inside and outside the main terminal — and now it's spread to where passengers least like to be held up: the security checkpoint.
On Tuesday, the airport closed the general lanes at the south security checkpoint in Terminal 1 as crews began installing four "innovation lanes" that in the long run could speed up screening by up to 40 percent.
But for at least the next three weeks, all passengers who are not part of trusted traveler programs will have to pass through the north security checkpoint. Two lanes at the south checkpoint will remain open, but only for passengers with TSA Precheck or Clear.
"Chalk it up to the pain of progress," said airport spokesman Patrick Hogan.
Over the past year, inbound and outbound roads have been torn up, escalators have been taken out and temporary walls have gone up throughout the terminal as the Metropolitan Airports Commission has embarked on $1.6 billion in improvements.
The latest disruption comes as automated screening lanes are added. During installation and testing, there will be four fewer lanes available to screen passengers and some extra long walks from the baggage drop to the gate.
Traveler Linda LaCroix, who was heading back to Arizona after visiting her parents in Eagan, shrugged in disappointment after she checked in with Delta and tried to use the adjacent south checkpoint Tuesday morning. She was directed to the other end of the terminal.
"My flight probably is leaving from this end," she said as she made the trek down the corridor. "I hate when you have to wait [at the checkpoint] because it can get really long."
