Metro has announced Blue Line closures for 2019.
The line is in a six-year-long, $1.2 billion rehab project.
The closures will happen in two, four-month segments.
The first closures will begin on Jan. 26, starting in the southern stretch of the line from downtown Long Beach to the Willowbrook/ Rosa Parks station.
In May, the northern stretch from Willowbrook/ Rosa Parks station to 7th Street/ Metro Center stop will be closed for four months.
The Willowbrook/ Rosa Parks station will be closed the entire eight months as part of a $66 million overhaul.
During this time, the Expo Line will be suspended for 45 days at 7th Street/ Metro Center and the Pico Stations.
The Expo Line will continue to run between LATTC/Ortho Institute Station and downtown Santa Monica.
More than 90,000 commuters use the Blue Line daily.
It's the oldest line in the Metro system.
