Elected officials and area business leaders will attend the launch of Detroit's light rail system.
The QLINE is scheduled to begin picking up passengers Friday following a celebratory program at Grand Circus Park downtown.
Speakers will include Gov. Rick Snyder, Mayor Mike Duggan, and businessmen Roger Penske and Dan Gilbert.
The project was led by private businesses and philanthropic organizations in partnership with local, state and the federal government.
Its 6.6-mile roundtrip route will extend from the downtown riverfront to Detroit's New Center Area.
The QLINE features three-piece streetcars that are each 66 feet long and can carry an average of 125 passengers per car.
The daily walk-up fare is $1.50 and is good for three hours.
