It’s a major cog in the mass transit connection to LAX. It is a train station opening on Friday that will be the closest to the airport and soon will connect to a people mover.

In the words of L.A. Mayor Karen Bass, today marks the “beginning of a new era in our city.” And to celebrate the big opening, rides across the entire Metro system—rail lines, buses, Metro Bike Share and rideshare service Metro Micro—are free from Friday through Sunday.

The Los Angeles-area transit system will achieve a major milestone on Friday with the long-awaited opening of the LAX/Metro Transit Center station, bringing rail service the closest it has ever been to Los Angeles International Airport and giving travelers a new car-free option for reaching the airfield.
