The Florida Department of Transportation will accept bids May 25 for rehabilitating the Mathews Bridge over the St. Johns River in Jacksonville—a coating project budgeted at $25,492,576.
The steel through-truss bridge—7,736 feet long and 58 feet wide—carries the Arlington Expressway between downtown Jacksonville and Arlington.
The Mathews was the first high-level cantilever truss bridge in Florida when it was built in 1953 and is eligible for the National Register of Historic Places.
The project includes cleaning and recoating structural steel surfaces along the approximately 1.4-mile span. The current coatings include lead; containment and SSPC-QP 2 certification are required.

The work also requires installing cathodic protection systems, including impressed current and integral pile jacketing; replacing neoprene pads on bents and piers; rehabilitating expansion joints; and installing new steel elements, including structural steel, ladders, platforms, and railing.
In 2007, the open grate bridge deck was replaced with a $12.9 million Exodermic deck, resulting in a concrete riding surface. It was the first Exodermic deck used on a steel through truss bridge.
An Exodermic (composite, unfilled steel grid) deck is comprised of a reinforced concrete slab on top of, and composite with, an unfilled steel grid. The deck typically weighs 35% to 50% less than the equivalent rebar-reinforced concrete slab, the manufacturer says.
