State auditor's report: BART will need $9.6 billion of voter approved funding

BART directors are exploring whether to put a $1 billion bond measure on the ballot as early as next year.

This, after California's state auditor finds the transit system needs nearly $10 billion through 2024 to replace its aging infrastructure. The report says BART would need to ask voters for the money. The agency does not have a contingency plan if the measures are not passed and that could cripple the commute.

The state auditor says BART's infrastructure is 40-years-old and "at, or close to the end of its useful life."
