This week marks a milestone in the Elizabeth River Tunnel project in Virginia. The project is one of the largest infrastructure projects occurring in the U.S. right now. It will place a two lane tunnel next to an existing tunnel connecting Norfolk and Portsmouth, Virginia and thus double the tunnels capacity and reduce commute times. SKW Contractors team, a joint venture between Skanska, Kiewit, and Weeks Marine, are overseeing the public-private partnership project and are responsible for submersing eleven 16,000-ton hollow concrete elements into a special trench at the bottom of the Elizabeth River.

The “I Lift NY” floating super crane arrived at the Tappan Zee Bridge this week and yesterday had to do the limbo to travel to the other side of the bridge. The crane made its way up the Hudson River from Jersey City on Monday after completing its journey from San Francisco through the Panama Canal earlier this month. Around 5 pm yesterday, a tugboat helped guide the crane north underneath the existing bridge and to the location where the new bridge is currently under construction. Workers on site prepared for the crane's arrival by removing the existing bridge’s navigation light from under the bridge to give the crane a little more clearance. The barge carrying the crane was also filled with water to make it ride lower in the water. The crane was able to squeeze under the existing bridge without any problems and will now be anchored on the other side for the next couple of years. It uses special steel anchors, called spuds that are planted in the river bottom to keep from moving.
The Aral Sea, once the fourth largest lake in the world is today rapidly shrinking, as a result of the diversion of the two major rivers feeding it, back in the '60s. The effects of the Aral Sea desiccation are widely felt in the local population and the ecosystem, transforming the area in the borders between Kazakhstan and Uzbekistan into a vast toxic desert. Watch the video below with NASA's satellite pictures of the area, showing the water level changes over the years!
