Painting the Walt Whitman Bridge

by Kevin H. Keith, PE, JMT, Inc. and David M. Hatherill, PE, Corcon, Inc.

The Delaware River Port Authority let their largest painting contract ever, over $57,000,000 to blast and paint the entire suspension span of the Walt Whitman Bridge including the complete interior and exterior of the towers, deck support steel in the anchorages, suspension cables and various steel repairs. This article describes the painting project itself, the skills required for the construction and engineering teams, unadvertised skills such as dealing with the nesting Peregrine falcons and the complexities of traffic control of 120,000 vehicles each day.

Waterjetting & Surface-Tolerant Coatings: UHP on the Luís I Bridge in Porto, Portugal

by Joao Azevedo, Sherwin-Williams Protective & Marine Coatings

The iconic Luís I Bridge, constructed in 1886, spans the River Douro between the cities of Porto and Vila Nova de Gaia in northern Portugal. In 2003, the bridge's upper deck was converted to carry the D Line of the Porto Metro light railway, necessitating an additional 22,000 square meters of extra structural steelwork requiring protection from corrosion. With the bridge protected since construction by a lead-based paint system, this article discusses the rationale behind employing ultra-high-pressure waterjetting and recoating the bridge with an ultra-high-solids, damp-surface-tolerant epoxy coating and reports on its success after 15 years in service.
