Occoquan Bridge Built with Defective Grout
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.
Virginia Department of Transportation spokeswoman Joan Morris said the grout does not pose and immediate safety threat, and said VDOT will continue to monitor and check the bridges for signs of rust or cracking — neither of which has been found on the Occoquan or Wilson bridges.
The Occoquan River Bridge, often referred to as the Route 123 Bridge, was completed in 2007. The new bridge was built to accommodate six lanes of traffic, and was constructed 44 feet higher to allow for taller sailboats to pass underneath.
The new Wilson Bridge over the Potomac River in Alexandria opened the following year.
