Crews replaced 31 aging expansion joints on the Interstate 5 interchange with West Seattle and Beacon Hill, and on mainline I-5 in South Seattle. Expansion joints link together concrete bridge slabs in a way that allows the bridge to bend and flex with heavy, uneven traffic and the annual freeze/thaw cycle. Expansion joints stretch across all lanes of the highway or bridge.
Work began in January 2013 and wrapped up in early May 2013.
New, stronger expansion joints extend the life of the roadway and are less likely to fail. Failing expansion joints can lead to collisions, emergency closures and expensive urgent repairs.
