SE 8th St Traffic Improvement Committee


SE 8TH STREET Traffic Improvement Project
The City of Bellevue Neighborhood Traffic Safety Services has received numerous requests to address residents’ concerns with vehicle speeds and cut-through traffic over the years on SE 8th Street, between 100th Ave SE and Bellevue Way.  Evaluation and analysis of the traffic concerns were postponed until the Bellevue Utilities sewer project that closed SE 6th Street was complete.
A number of traffic studies and field visits were conducted and studies show that there is a significant amount of cut-through traffic using SE 8th Street and SE 6th Street  to get to Bellevue Way in the afternoon. The results from the traffic studies and an initial survey to residents were sent out in April 2013. A traffic committee was formed of resident volunteers to work with City staff to help develop a plan for improvements to address the traffic concerns.
In January 2014, a project ballot has been sent to the neighborhood area and an open house.  Of the survey’s respondents, 86% supported the proposed plan.  
Chicane - Interim Installation
During the ballot process, the design of the chicane was adjusted to  address adjacent property concerns.  A temporary chicane was installed with paint and 18-inch high white delineators to be evaluated for effectiveness at the end of summer. 
In April 2014, the following was installed:
  • "Playground" and "Residential Area" signing and "25 MPH" pavement markings on SE 6th St
  • an elongated speed hump just east of 101st Ave SE
  • an interim chicane on SE 8th St between 101st Pl SE and 102nd Ave SE
  • and an elongated speed hump on SE 8th St, east of 103rd Ave SE


In September 2014, the temporary one-lane chicane was removed due to safety concerns. The traffic committee will evaluate additional alternatives to help address cut-through traffic concerns.
