Block Island Lighthouse Relocation

Block Island Lighthouse RelocationThe Southeast Lighthouse on Block Island is located 15 miles off the coast of Rhode Island. Built in 1873 and weighing in at over 2000 tons, this combination house and lighthouse was moved 300 feet back off the threatening seawall. Because of its magnitude, the total job was laid out step-by-step with CAD drawings. These design drawings located where each item of steel beam, blocking, and equipment was to be placed. After intricately placing the steel beams, the structure was raised with 38 60-ton jacks. Once raised, it was placed on caterpillar-type rollers and supported by floating hydraulic jacks. Its direction had to be changed — while moving — three different times before reaching its final resting place.
