We widened SR 900 from Newport Way to the vicinity of SE 78th Street (SE 82nd Street and Talus Drive) in Issaquah. This continued the widening we completed in 2004 from I-90 to Newport Way.
We added a general purpose lane in each direction, a bike-only lane and a raised sidewalk. Together, these improvements will help reduce traffic congestion and improve safety.
Widening the roadway from one lane to two, and adding a bicycle lane and a raised pedestrian walkway will increase the safety of the roadway for drivers, bicyclists and pedestrians.
Continuing the widening of SR 900 to SE 82nd and synchronizing the signals will improve congestion and help traffic flow smoothly.

This project included measures to prevent flooding and improve fish habitat in Tibbetts Creek and Tibbetts Creek tributaries.
Partnerships & Cooperation
The first phase of this project (completed in December 2004) was a collaborative effort by the Washington State Department of Transportation, the City of Issaquah, Sound Transit and King County. A large portion of funding for the first phase of the project came from Talus, a master-planned development that continues to grow just off SR 900. We began work in July 2003 and completed construction in December 2004.
We selected Icon Construction to build the project in spring 2008. We began work in August. In spring 2009 crews installed a water pipeline for Cascade Water Alliance as part of the Tacoma-Cascade Pipeline project. Installing the pipeline as part of the project means crews won't have to tear up the newly-widened roadway to install the pipeline at a later date.
Crews opened the new lanes to traffic on April 14, 2010. Remaining work on the project was completed by fall 2010.
