Now that the tunnel-boring is complete, what’s going on at the Central Subway construction sites? We’ve seen the cranes dangling ever so close to the department stores nearby, and crews putting together what looked like enormous metal beams. I stopped by to ask one of the construction workers, who told me that they were putting together piles (a post-like foundation) to support the station walls. The piles will be driven into the ground to bear the weight of the soil around the stations.

Starting this Friday, July 11, through the weekend, you’ll see the pile installation on the corner of Stockton and O’Farrell Streets. SFMTA says that construction work will be in progress around the clock until Monday, July 14, at 5 a.m.

The Central Subway segment of the T-Third line is slated to open in 2019.
