look inside an expansion joint. This gap allows theconcrete slabs to expand and contract as the temperature changes. Crews will fill this gap in with concrete and a flexible rubber strip seal.

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.
