OCCOQUAN, Va. — A bridge that carries commuters over the Occoquan River is one of two in the area constructed with defective grout.
The Occoquan River Bridge and Woodrow Wilson Bridge, which carries east coast traffic on I-95 over the Potomac River, were identified as two of at least 34 bridges constructed with grout contaminated with chloride making it prone to rust. The grout was manufactured in Ohio between 2002 and 2010, according to the Baltimore Sun which first broke the story.
