I remember when the system opened. It looks like there are 10 stations that have been added since then.
Yup. The system has expanded. Both in the north (that yellow line section) and in San Mateo county to the Airport (which until recently, had very disappointing ridership numbers for an extension that cost billions).
Now, if this tax passes (with the suspicious surge that makes it close to passing), it will take BART one step closer to ‘completing’ one of their long time dreams. BART around the bay.
