King County is committed to bridge safety

King County anticipates closing 35 bridges over the next 25 years if we don’t get enough funding to repair and replace aging and obsolete structures.

The Road Services Division regularly inspects the bridges it is responsible for maintaining. Sometimes we have to close bridges that are at risk including the Alvord T Bridge, which we will be closing in June. When we are able to get grant funding, like we did with the South Park Bridge, we can replace bridges at risk rather than close them permanently.

Current bridge projects

We're building a new bridge in South Park - follow the progress.
