The “breakthrough” media event for CALTRANS’ Devil’s Slide Tunnel project was this past Friday. A large crowd of politicians, news crews and locals were on hand as a road-header broke through a shotcrete face in a ceremony to mark the completion of the excavation portion of the first of two tunnels. It will still be over a year until the tunnels are opened to traffic. The second tunnel is expected to breakthrough as early as this week. (Photo by SFGate.com)

A pile static load test went awry in Singapore when a pyramid of dozens of concrete blocks used for the reaction force toppled over into Gilstead Road. The force of the collapse caused a gas main to rupture but there were no reports of injuries. Click through for the video.
