Steel from WTC heads to Pa.

A steel beam salvaged from the World Trade Center is transported across the George Washington Bridge on its way to Coatesville, Penn., as the New York City skyline stands in the background Wednesday April 14, 2010. A mile-long convoy of 28 tractor trailers carried 500 tons of steel from the twin towers to become the centerpiece of a planned National Iron and Steel Museum in Coatsville, Penn., where the steel was created 41 years ago.
