Corridor Concept
Newport Way Concept


The City of Issaquah developed a preliminary design, also called a corridor concept, for Newport Way Northwest between SR 900 and SE 54th Street that was adopted by City Council on December 4, 2017 (AB 7484). 

The project included an extensive community outreach process of neighborhood meetings, community workshops and stakeholder meetings in order to receive input on the issues and needs for the corridor.  Summaries of these public meetings including presentation materials and participant comments can be found in the appendices of the design report and appendices.  

Through the community outreach process, the following project objectives were developed: 

  • Improve pedestrian and bicycle facilities and roadway crossings
  • Improve vehicle access to neighborhoods
  • Design for future traffic on the corridor
  • Maintain or enhance the corridor character
  • Provide continuous improvements from SE 54th Street to SR 900

Corridor Concept Timeline 
The design team evaluated several alternatives for roadway cross-sections and intersection treatments, such as roundabouts, raised intersections, turn lanes, and various types of pedestrian and bicycle facilities. 
The adopted concept described in the Design Report (and appendices) was selected based on the engineering and operational analysis, and direction from the community outreach process. 

Cross Section

The cross section shows the proposed facilities that are to be constructed along Newport Way Northwest, including travel lanes for vehicles, planting areas, sidewalks, bicycle lanes and a multi-user trail on the north side of the street. A center left turn lane or a landscaped median is included for the segment of Newport Way NW between Southeast 54th Street and Northwest Oak Crest Drive. The segment between NW Oak Crest Drive and the Bergsma Development access road does not include the center left turn lane/median to reduce the roadway width and because there is limited need for access to property.

Next Steps 
Council approved the extension to the City’s consultant contract on January 16, 2018.  The project team is now working towards a preliminary 30% design submittal this Spring. In the meantime, you may see surveyors or environmentalists onsite as we supplement our topographic survey and prepare for environmental permitting.  Our real estate support consultant will also be contacting property owners along the corridor to obtain a right of entry as needed. We anticipate holding another open house to update the community on the design progress this summer.
