6. The Bronx-Whitestone Bridge Lost 6,000 Tons

In August 2001, MTA Bridges and Tunnels initiated a $286 million restoration process of the Bronx-Whitestone Bridge, which included efforts to bring the bridge back closer to its original design. Along with the removal of its heavy steel trusses, the old concrete bridge deck was replaced with an orthotropic deck and improvements were made to the electrical, lighting and drainage systems. The overhaul was completed in 2008 and the structure lost 6,000 tons (a quarter of its total suspended weight) in the process.
