ORLANDO, Fla. -

Orlando International Airport will be spending $65 million to replace four of its people-movers in the airport.

The four movers have been running to and from two different sections of the airport since 1981, when OIA opened.

Crews will install one at a time, so that people can still be transported to their gates, officials said.

The new shuttles should be up and running by spring 2018.
