PPG supplies Duranar and Duracron metal coatings for Port of Miami Tunnel
4,200-foot-long highway tunnels that travel under Biscayne Bay, connecting the MacArthur Causeway on Watson Island to the Port of Miami on Dodge Island.
PPG Industries’ coil and building products group announced that it supplied Duranar XL and Duracron coatings to the recently opened Port of Miami Tunnel, which is made up of two 4,200-foot-long highway tunnels that travel under Biscayne Bay, connecting the MacArthur Causeway on Watson Island to the Port of Miami on Dodge Island.
Duranar XL coating—specified by Arquitectonica, the Miami-based architectural firm that designed the tunnels—is a three-part coating system consisting of a urethane primer coat, a decorative color coat and a protective fluoropolymer clearcoat. Arquitectonica selected Duranar XL Crystal Blue coating to cover the 4,000 metal panels lining both sets of tunnel walls.
Phil Buhr, PPG product manager, coil and building products group, said the selection of Duranar XL coating for a transportation project is unusual but makes sense for the Port of Miami tunnels.
“As a high-end coating system, Duranar XL coating is more commonly specified for monumental architectural projects and storefronts that demand long-term colorfastness, gloss retention and chalk resistance,” he said. “All of those performance factors and the ease of cleaning made Duranar XL coating an ideal choice for a high-visibility project like this, where the architect and project owners were determined to find a coating that would look good even after decades of constant exposure to humidity, salt air and automobile exhaust.”
