I-90 Cross-Lake Washington Tolling - Project Map

I-90 Cross Lake Washington Tolling Project Map

The Cross Lake Washington Corridor is made up of the I-90 and SR 520 bridges, two parallel highways - 3.5 miles apart -  that operate as one system to connect the region’s major employment and population centers over a 22-mile long body of water.

In 2011, WSDOT began tolling the existing SR 520 bridge to generate $1 billion in revenue toward completing of the new bridge. An additional $1.4 billion is still needed to complete the I-5 to Medina: Bridge Replacement and HOV Project that would replace the vulenrable Portage Bay and southwest bridge approach structures.
