Los Angeles, California.
The 8.5mile long Crenshaw/LAX Line is currently under construction and will open in 2019. It runs north-south from Expo/Crenshaw Station on the Expo Line to Green Line near Aviation/LAX Station. The line runs through Inglewood and Los Angeles.
Its route alignment is a mix between above-grade, at-grade, and below-grade. There will be 8 stations; 3 stations will be underground, Expo/Crenshaw (connection to the Expo Line), Martin Luther King Jr, and Leimert Park. An infill station is planned at 96th Street to accommodate a connection for the Airport Metro Connector (people mover to LAX/Los Angeles International Airport).
It is expected that 2 services will use the Crenshaw/LAX Line: Expo/Crenshaw to Redondo Beach (western terminus of the Green Line) and Aviation/Century to Norwalk (eastern terminus of the Green Line).
