County to make safety improvements near Liberty High School

June 19, 2012

By Staff

King County road crews plan to make safety improvements near Liberty High School soon.

The county King County Road Services Division received federal grant funding to complete the project east of Renton. Crews plan to restripe the westbound lanes at the intersection of 168th Avenue Southeast and Southeast 128th Avenue Street — north of Liberty.

Get involved

Submit comments about the project by June 29 to Community Relations, King County Department of Transportation by phone at 206-263-9770, by email to or by mail to 201 S. Jackson St., MS: KSC-TR-0824, Seattle, WA 98104.

Plans also call for the existing traffic signal to be changed to provide a left-turn signal. Expect improved pedestrian facilities to result from the project, too.

Officials expect the changes to reduce the number and severity of rear-end collisions involving motorists waiting to turn left from Southeast 128th Avenue Street onto 168th Avenue Southeast.

In the existing arrangement, a curve limits the visibility of vehicles stopped in the inside westbound lane. Advance warning signs and flashers located east of the intersection should help alert westbound motorists of changes and the need to merge to the right.

Construction is expected to begin by September and be completed by the end of the year. Students return to Liberty and other Issaquah School District campuses Sept. 4.

No full road closure is expected as crews complete the work. Expect to see project signs on the approaches to the intersection to alert motorists a few weeks prior to the start of construction.
