Placing Winter Concrete: Pearl Harbor Memorial Bridge

AbstractPlacing concrete in cold weather is problematic. The contractors at the Pearl Harbor Memorial Bridge in New Haven, Connecticut, have battled relentless winters to complete the first extradosed bridge in the United States. Their success hinged on detailed winter concreting plans developed to work safely and efficiently during very cold weather. The plans contain multiple concrete mix designs as well as specific heating configurations to keep the various placement areas within acceptable temperature ranges necessary to produce quality concrete. The plans have shown to be effective, allowing placements to occur through a number of snowstorms.
