A second harbour tunnel is within the State Infrastructure Strategy's development plans in Sydney. The new tunnel will be an extension to the M2 motorway, connecting Balmain to Lane Cove, and will offer motorists a bypass to the congested inner city.

An animation was released last week showing what a ride on the world’s tallest roller coaster will feel like. The 570-foot roller coaster called “Skyscraper” will be built in Orlando, Florida and will open in 2017. It was designed by Orlando-based architectural firm HHCP and will be built by Eufforia. The “Skyscraper” will be built on top of a new 495,000 square-foot shopping and entertainment complex on Orlando’s International Drive. Once completed, the roller coaster will overtake the 465-foot tall Kingda Ka at Six Flags Great Adventure in Jackson, New Jersey as the world’s tallest roller coaster. Construction is set to begin early next year and take two years to complete.

The other walkway, over the east side of the bridge, will be opened on December 1.

According to the latest projections, the new Bay Bridge eastern span will be completed $35 million over budget. Caltrans is shifting funds from other bride projects from around the state to make up the deficit. The new Bay Bridge eastern span connecting San Francisco and Oakland, California opened in September of last year.  Caltrans has been optimistic throughout the duration of the project that the completed bridge would cost less than the $6.4 billion price tag. That figure includes $900 million for cost over runs and contingencies. However, it is estimated that there is still $110 million of unfinished work left to complete the eastern span and Caltrans expects their original estimate of $100 million to tear down the old span to be lower than the actual cost. Taking into account the remaining work that needs to be done as well as cost overruns, Caltrans expects to have a $35 million deficit when the bridge is completed.
