The Washington State Department of Transportation improved safety for pedestrians and bicyclists with a new shared-use, gravel trail near Interstate 90 in Issaquah. The trail connects the east end of the Issaquah-High Point Trail to the west end of the Preston-Snoqualmie Trail. Crews will build the trail in two stages. This connector trail fills a gap in the Mountains to Sound Greenway regional trail system.
Before construction, pedestrians and bicyclists were at risk of colliding with vehicle traffic in-between the east end of the Issaquah-High Point Trail and the west end of the Preston-Snoqualmie Trail. They shared narrow local streets with cars and trucks or used the shoulder along westbound I-90 to connect between trails.
- June 2009 - We advertised Stage 1 of this project for competitive bidding.
- July 20, 2009 - We awarded the project contract to KLB Construction, Inc. of Lynnwood.
- June 2010 - We began construction on Stage 1.
- December 2010 - We completed construction of Stage 1.
Separating trail users from I-90 and local streets improves safety for drivers, pedestrians and bicyclists.
| Protects Environment
A new pedestrian bridge and a converted railroad trestle will prevent trail users from disturbing the East Fork Issaquah Creek and nearby wetlands.
Retaining walls located at steeper sections will help minimize impact to the natural environment by keeping the trail intact.
Partnerships & Cooperation
We worked with the Mountains to Sound Greenway Trust to complete this connector trail that fills a gap in the Mountains to Sound Greenway regional trail system.
