SAN FRANCISCO (KCBS) – Workers started pouring the foundation for San Francisco’s new Transbay Transit Center on Thursday, the latest milestone in the transformation of the Bay Area’s transportation landscape.
The giant Putzmeister concrete pumping machines began filling the vast six-story underground cavity at First and Mission streets, where the new Transbay Center will stand.
“We’re going to be pouring 142,000 cubic yards of concrete, which is the equivalent of 30 Olympic-size swimming pools,” said Maria Ayerdi-Kaplan, head of the Transbay Joint Powers Authority.
