S Holgate Street to S King Street Viaduct Replacement

SDOT is working with WSDOT to coordinate relocation of underground utility and water systems near the southern portion of the viaduct between S Holgate Street and S King Street. The work is part of city street improvements that will help keep traffic moving during construction to replace the southern mile of the viaduct.

To help visualize what this project looks like and how it will be sequenced check out WSDOT’s interactive simulation. In the coming weeks the SDOT Blog will post articles about the start of construction for this project.
