DOT will open East Sunset Way construction bids

April 6, 2010

By Staff

State Department of Transportation officials will open construction bids for the East Sunset Way interchange April 7.

Workers will widen the narrow, curved roadway from a single lane in each direction bracketed by concrete barriers to wider lanes bracketed by road shoulders, curbs and a sidewalk. Crews will also replace a temporary support wall with a permanent support for the widened roadway. The project will also require workers to reconfigure storm water retention ponds adjacent to the site.

Officials plan to start construction on the estimated $3.5 million project next month. Work should last about six months. Although most work will take place off the roadway, the project will require up to 60 nighttime closures, when a single lane will remain open and flag crews will direct traffic.

The state started advertising the project to contractors March 8.

Crews completed most of the interchange in 2003. Workers left the East Sunset Way piece unfinished in order to link the junction to the planned Southeast Bypass.

City Council members canceled the proposed 1.1-mile roadway across Tiger Mountain in 2008, after 12 years of planning and $4 million.

The interchange work completed in 2003 — billed by the DOT as a $117 million congestion-relief project — created additional access to Issaquah and the Sammamish Plateau.
