The planned BART route to SFO, originally expected to open last year appears to have developed more delays. Officials have said they will no longer make projections on an opening date. Once the contractor turns the extension over to BART, there will be 2 ro 3 months of testing.
This is something like the 4th missed announced start date. The hope is to be open by this summer, but no one wants to make anything resembling a promise on that.
