Marine Industry Coating Systems: Selecting and Sourcing

The Louisiana Department of Transportation and Development awarded a contract of $6,223,574 to Texas Bridge Partners, LLP, of Humble, TX, to perform superstructure and substructure painting and repairs on the Sunshine Bridge.

The contract required SSPC-QP 1 and QP 2 certification.

The bridge carries four lanes of US 70 across the Mississippi River at St. James Parish, LA.

The 1.5-mile-long Sunshine Bridge was once considered a "Bridge to Nowhere."

Criticized when it opened in 1964 as a “Bridge to Nowhere,” the bridge now carries about 16,000 vehicles a day between Sorrento and Donaldsonville, in the Baton Rouge area. It also plays an important role in storm evacuation and in industrial development along the Mississippi.

Scope of Work

This project involves cleaning and recoating structural steel surfaces on a 3,160-foot-long segment of the east approach and a 1,444-foot-long segment of the west approach to the Sunshine Bridge, an 8,236-foot-long cantilever bridge over the Mississippi River.

The project also includes repairing 61 trestle bent base plates that are coated with lead-based paint.

The steel will be abrasive blast-cleaned to a Near-White condition (SSPC-SP 10) and coated with an inorganic zinc-rich primer, an epoxy-intermediate, and a polyurethane finish.

The existing coatings contain lead; Class 1 containment according to SSPC-Guide 6 is required. The contractor must furnish NACE-certified coatings inspectors as part of its quality control plan.
