Now that all those noise panels are up on the I-5 Ship Canal Bridge, have you noticed any difference? WSDOT says it just finished its first tests, and the results are mixed. They sent crews into the field last week and took noise measurements at 18 locations. WSDOT says the numbers show the panels are working as well as predicted in about a third of the locations, but not as well as predicted in the majority of the locations. The biggest noise relief came on the west side of the bridge. You can check out the noise measurements here.
WSDOT will continue to take noise measurements once each quarter and then annually for 3 years. 700 noise reducing panels were put in place as part of a $7 million pilot project with money allocated by the state legislature.Tweet
