The escalator replacement on the Millennium line platform is almost finished after about 9 months. However the transfer between the Expo and Millennium lines is about to get a lot worse. The escalator on the older overpass walkway will be closed for a year.
Estimated Timeline: Dec. 2023 to Fall 2025
Work on the two escalators serving Millennium Line’s Commercial platform began Dec. 2023. These new and improved escalators will open to customers Sept. 27, 2024. On the same day, the two nearby escalators serving Expo Line platforms 3 and 4 (near Booster Juice) will close for replacement. The accompanying stairs will also close to ensure the safety of the public and crews throughout construction. The elevator will remain open for those who need it.
