Stadium Drive at the bottom of the hill near North Glass Bowl Drive on Main Campus will close this afternoon.
Traffic will be maintained to the middle of Main Campus through parking lot 4 by Savage Arena, according to Michael Green, director of energy management in Facilities and Construction.
Contractors from Titan Mechanical Inc. of Perrysburg will be installing a new chilled water line across Stadium Drive.
If weather cooperates, the project is expected to be complete in two weeks, Green said.
