Old Bay Bridge Demolition Underway

Workers began tearing down the east span of the old Bay Bridge on Tuesday, nearly two months after the new bridge opened.  The demolition of the old bridge is expected to be a long, tedious process.  Construction workers will have to dismantle the bridge piece by piece.  According to one of the California Department of Transportation’s bridge engineers,  “the old bridge is the world’s largest armed bow and arrow. We have to de-string it very carefully or it will go boom.”  The $281 million demolition project is expected to take three years to complete.  This cost was already incorporated into the $6.4 billion price tag for the new bridge.  The 1.97 mile long east span opened in 1936 and is made of almost 59,000 tons of steel and 245,000 tons of concrete.  The majority of the steel will be recycled or reused, but some will be saved for a new park commemorating the old bridge.  The following link contains a great slideshow of construction crews beginning the demolition of  the bridge.

A deal was finalized between the Port Authority of New York and New Jersey and a team of private companies to replace and demolish the existing Goethals Bridge connecting Staten Island and New Jersey. The team, named the NYNJ Link Partnership, is comprised of Macquarie Infrastructure and Real Assets Inc., Kiewit Development and Infrastructure, Weeks Marine, and Massman Construction. This is the Port Authority’s first public-private partnership and will be financed through tax-exempt bonds, loans, and developer contributions. The NYNJ Link Partnership is responsible for designing, building, financing, and maintaining the bridge. The replacement  bridge will improve the existing bridge by having 6 12-foot wide lanes, interior and exterior shoulders, a pedestrian and bike path, and a lane to be developed for buses, HOV, or light rail in the future.
