We will work with the Seattle Department of Transportation, King County, the Port of Seattle, Seattle Center and the stadiums to keep traffic moving during the closure. Alternate routes will be available. We will have WSDOT Incident Response Teams available to help clear blocking incidents or stalls. WSDOT, in partnership with King County Metro and the City of Seattle, recognized the potential effects of traffic closures during viaduct replacement construction and invested $125 million in projects designed to keep traffic moving. These investments include:
- $50 million for Seattle’s Spokane Street Viaduct widening project, which added a route into downtown with its new eastbound off-ramp to Fourth Avenue South.
- Phase 2 of the SR 519 project – a new I-5/I-90 westbound off-ramp to South Atlantic Street/Edgar Martinez Drive South which improved access to the waterfront and Port of Seattle.
- $32 million to fund additional bus service with 41 new bus trips on key routes connecting downtown Seattle to West Seattle, White Center and Burien and strategies to encourage use of transit, carpools and vanpools.
- New electronic driver information signs on I-5, SR 99 and other major routes leading to downtown.
