George Campbell AwardHalt Bridge

摘要

Located over the St. John's River, the Hart Bridge is the major traffic artery that services all sporting and entertainment events in downtown Jacksonville, FL. Rehabilitation work included major structural steel repairs, blasting, and painting.Structural steel repairs included major gusset plates, lateral horizontal struts, vertical column repairs, bearings, and other miscella-neous repairs. The existing coating system contained lead and was deemed hazardous; the bridge's proximity to a high school and a shipyard required SSPC-Guide 6, Class Al containment, air monitoring, and soil testing. The project required blast cleaning to Near-White (SSPC-SP 10) and application of a four-coat system.
