Travelers who plan to park at the main terminal at the Minneapolis-St. Paul International Airport or anybody picking up folks flying in may run into traffic jams Wednesday through Friday.

The road leading to and from Terminal 1 and its attached parking and rental car facilities will have lane reductions and shifts at times as preparation work begins ahead of a new 5,000 space parking ramp that will open in 2019.

Airport officials are still advising departing passengers to arrive at MSP two hours before their flight to allow enough time for parking, baggage check in and to pass through security checkpoints.

Although wait times at the checkpoints has improved from two weeks ago when some passengers needed an hour or more to get through security, "we're still experiencing high passenger volumes," airport officials said in a statement.

Airport officials are reminding passengers that parking at Terminal 1 is extremely tight during the middle portion of the week. They suggest using the Quick Ride Lot off Hwy. 5 and Post Road. Shuttles to and from the lot and Terminal 1 run 24 hours. Parking is $3 per or a maximum of $14 per day.

Parking at Terminal 1 runs from $22 to $24 for a 24-hour period.
