Delta QAD Bridge Repair
Terminal D, LaGuardia International Airport, Queens, NY

Madsen Engineering provided the structural repair design for Delta LGA Bridge L11, located at La Guardia Airport’s Terminal D. The first of the bridge’s 22 spans, an enclosed concrete rigid frame – reinforced concrete bridge deck on precast reinforced concrete bearing walls supported by continuous pile caps – exhibited serious deterioration, according to a Port Authority of NY and NJ Bridge Condition Survey. Madsen Engineering worked with the architect, RCGA and the geotechnical engineer, GZA, to provide repair details for the continuous pile caps and grade beams, repair of the soil erosion areas around the pile caps, support for new door openings and other miscellaneous repair details for the bridge structure.
