Spokane Street Viaduct Widening
The Seattle Department of Transportation (SDOT) is widened and improved the South Spokane Street Viaduct - the 60-year-old elevated roadway that carries more than 70,000 vehicles daily between I-5 and the West Seattle Bridge.
The South Spokane Street project provided these benefits:
- Created a new two-lane eastbound off-ramp leading to Fourth Avenue South
- Relocated the westbound on- and off- ramps to a new First Avenue South ramp
- Widened the upper roadway to the north by 41 feet - between Sixth Avenue South and East Marginal Way
- Rebuilt the lower roadway in concrete, with new curbs, sidewalks and improved pedestrian and bicycle access
The project was completed in 2012. The Port of Seattle is contributed $3.4 million to the City of Seattle for this construction.
