Project Background & History


This project will widen Issaquah Fall City Road to four lanes, between 242nd Ave SE and Klahanie Dr SE. The additional lanes along with roundabouts at 242nd, 247th, and Klahanie Drive will improve traffic flow and reduce commute times on this highly-congested roadway. 

Goals and Benefits

As part of the newly annexed section of the City (January 1, 2016), SE Issaquah-Fall City Road is a vital connection route to residents of the City of Sammamish and surrounding communities. This project will double the existing two-lane section to a four-lane section and promote the City’s goals of complete streets by including bike lanes, sidewalks, landscaping, and a protected student crossing at Pacific Cascade Middle School. A bridge located between 247th and Klahanie Drive will raise the roadway to improve safety and meet federal driver stopping sight distance requirements. North Fork Issaquah Creek will be removed from a culvert underneath the roadway into a stream channel spanned by the bridge.

Project milestones

The 60% design plans, specs, and estimate have been delivered and work has begun on moving to 90% completion. The 90% plans are due to be completed this summer with a 2019 construction start date.

Connecting Washington Logo

A $5M CONNECTING WASHINGTON grant has been awarded to the project. Funds will be allocated for project construction costs, with $3.5M in Phase 1, and $1.5M for Phase 2 construction.

NOTE: The phase 1 budget estimate has been modified to include a bridge. Please keep in mind that TIP values are planning level estimates that include design, construction, right of way and environmental estimates. Engineer's quantity & cost estimates are developed continually throughout the design process, and increase in accuracy as the project nears construction.

public utilities

Sammamish Plateau Water is planning to replace approximately 800 feet of an existing 8-inch water main crossing the North Fork of Issaquah Creek.
