HAYWARD (CBS SF) — BART on Thursday canceled the final planned weekend shutdown of service between the Bay Fair and South Hayward stations in early October after the most challenging parts of a track replacement project at the Hayward station were completed ahead of schedule.

Back in early August BART crews began replacing aging track components like rock ballast, wooden ties and track switches near the Hayward station on weekends. BART completed a similar project at the Orinda station earlier this year.

The weekend shutdown no longer taking place was planned for Oct. 3-4. BART crews are expected to continue work on the project over the next several months, but that work is not expected to require track closures that affect riders.

Many of the components replaced as part of the Hayward station project were almost 50 years old, according to the district.

BART officials say they’re planning to begin a similar track rebuilding project near the Richmond station early next year that will require four weekend service closures between mid-January and the end of February.
