The new Orange Line with service to Miami International Airport went live Saturday.

Two service lines make up the 22-mile long Metrorail. The green line will run on the existing track. The new, orange line will run from Dadeland to Miami International Airport.  It will branch off from the old track at the Earlington Heights Station.

Riding the new line from the Earlington Heights Station to Miami International Airport takes approximately four minutes.

"The major factor here is ease and travel," said Marc Henderson with Miami International Airport. "That's one thing the airport is always concerned about. How easy is it for you to get to us and then get on the plane to go wherever you're going."

Metrorail rides to M.I.A. will cost $2 per trip and $4 per day for parking at the Metrorail lots.

The Orange Line is the result of a $506 million project. It has been in the works since 1984.

"It's a comfortable, convenient, and affordable ride into downtown going South," said Ysela Llort with the Miami-Dade Transit.
