The under side of the San Francisco BART extension–Pillar with earthquake supports.

Waiting for a door-to-door van at San Francisco International Terminal 3, I noticed the detail of the BART pillars that are massively reinforced against the next San Francisco earthquake. A somewhat grimy view in daytime is quite charming at night.

This is an iPhone6 photo; amazing how often that is the only camera available when you need one for a snap.

Cheers, Carto
