Reasons for Requesting a Temporary Noise Variance:
Completion of all construction activities during only daytime hours would be unreasonable in light of public and worker safety. It would require multiple significant closures of SR 520 and I-5, which would
result in:
Extensive delays to the traveling public, Increased traffic volumes on city streets and nearby highways, A potentional increase in the number of accidents in the project work zone,
Completion of all construction activities during only daytime hours would substantially extend the construction period and increase the economic cost to taxpayers. Increased direct project costs are estimated to be in the range of $50 to $80
million. Added indirect costs (associated with daytime traffic impacts) to the delivery of people, goods and services in the region are estimated to result in an economic impact to the region in the magnitude of
$500 million.
