According to ENR, the U.K. government has approved the 7-year, $32-billion London Crossrail Project which will reportedly be Europe’s biggest civil engineering project. It will include 41.5-km of tunnels 6-m in diameter laid out in pairs. The tunnels will pass underneath London and connect surface networks on either side of the city. Link after the break.

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)
