SAN FRANCISCO (KCBS) — BART will begin a retrofit project in the Transbay tube this weekend that will cause delays for late-night riders for the next several weeks.

BART will be doing single track service through t the Transbay Tube some weeknights so power supply upgrades can be completed in anticipation of the next step for the Earthquake Strengthening Project—a major retrofit to the make the system safer have it back up and running after a disaster.

KCBS’ Chris Filippi Reports:

BART spokeswoman Alicia Trost said they don’t have enough time to do the work during normal business hours.

“Any extra work we have to squeeze in, and what we do is we try to pick the hours that the least amount of passengers are riding our trains, and that is that 10 p.m. slot on a weekday,” she said.

Riders traveling after 10 p.m. should allow extra time as trains will have to share one track between Montgomery Station and West Oakland Station.

The next phase of strengthening work in the Transbay Tube will begin in March and continue for 13 to 14 months. This work will also require single tracking during late-night hours.

In addition to the Transbay Tubes, the Earthquake Strengthening Project that began in 2005 has included strengthening BART’s 34 stations, 22 miles of elevated track and its parking structures.
