The Spokane Street Viaduct is a freeway connecting the West Seattle Bridge to Interstate 5. It runs above South Spokane Street in the SoDo neighborhood of Seattle and is generally four to six lanes wide.
The viaduct was one of Seattle's first freeways, opened in 1945. Over the course of the next few decades, other traffic-separated roadways were built to create a continuous roadway between West Seattle and Beacon Hill, such as the "Fauntleroy-Southwest Spokane Street Viaduct" (which opened in 1965).[1] Upon completion of the high-rise West Seattle Bridge in 1984, the road comprising the Spokane Street Viaduct, the West Seattle Bridge and the Fauntleroy-Southwest Spokane Street Viaduct was referred to as the "West Seattle Freeway". However, a series of fatalities led to recognition that the aging Spokane Street Viaduct portion was unsafe to be used as a high-speed roadway.[2] In 1997, the Seattle City Council unanimously adopted a resolution to lower the speed limit and to request that the WSDOT remove the word "Freeway" from signs marking the entrances to the Spokane Street Viaduct and the West Seattle Bridge.[3][4]
From 2008 to 2013, the Spokane Street Viaduct section between Interstate 5 and State Route 99 was rebuilt and widened. The widened roadway has three lanes in each direction and shoulders. A new westbound on and off ramp was built at 1st Avenue South and replaced the dangerous 4th Avenue South off-ramp. A new eastbound off-ramp to 4th Avenue South opened August 16, 2010.
The loop ramp from the West Seattle Bridge to northbound State Route 99 was closed on May 2, 2023, due to the formation of a 5 by 4 feet (1.5 m × 1.2 m) hole that left steel rebar exposed.[5] It reopened a week later after the damaged concrete was removed and replaced by WSDOT crews.[6]
