Clough Creek Short Span Bridge Project

Short-span bridge proposed for 415th Ave./Way S.E.

Overview

The King County Road Services Division is seeking funding to replace culverts under 415th Ave./Way S.E. with a short-span bridge in order to protect the road from flooding.

The existing culverts are structurally sound and can handle normal creek flows, but during peak rain periods they can clog and cause water to flood the road. This has resulted in several recent road closures and required extensive maintenance and repairs.

If the project receives funding, the county would probably have to close the road for several weeks during construction. The earliest this would happen is summer 2010.

Public involvement

The county is hosted two community discussions about the project, and encouraged all interested members of the public to attend the meetings to learn more about the project. The meetings were held:

Tuesday, Aug. 11, 2-4 p.m. at the North Bend Library, 115 E. Fourth Street
Thursday, Aug. 13, 5:30-7:30 p.m. at North Bend Elementary School, 400 E. Third Street

Clough Creek culverts
The existing culverts that carry Clough Creek under 415th Ave./Way S.E. probably date from the 1950s. They are structurally sound but can become clogged, causing the creek to flow onto the roadway during heavy rains.

Road Services would like to replace the culverts under 415th Ave./Way S.E. with a short-span bridge similar to this one, which the division built over Patterson Creek in the Redmond-Fall City area in 2008.
