Concrete Crack Fallout: Will Epoxy Repairs be Enough to Save the 520 Pontoon Bridge?
Cracking pontoons and uneven distribution of stress are just a couple of the many problems plaguing contractors for the Highway 520 floating bridge over Lake Washington near Seattle.
A thorough inspection has uncovered several more cracks in the concrete that exceed WSDOT acceptability standards and are causing leaking and seeping. WSDOT project directors are confident that these pontoons can be repaired using a special epoxy resin designed to restore the integrity of the concrete supports and seal the concrete cracks.
The need for these concrete repairs has set back the completion date of the Highway 520 pontoon bridge by about six months, and the magnitude of the additional expense has yet to be determined. Some have speculated that the current problems may stem from alleged shortcuts in construction taken by contractors in an attempt to earn an early completion incentive payment. With the on-going investigation, necessary repairs, and more rigorous inspections, the project is now slated for completion in July of 2015.
