Trail Description

The Eastrail will be an uninterrupted 42-mile trail that will connect the Eastside like never before and provide the communities of Renton, Bellevue, Kirkland, Woodinville, Snohomish, and Redmond with new opportunities for non-motorized recreation and transportation.

Currently 13 miles of the Eastrail are open, 5 of which are owned by King County. The Eastrail has numerous trail sections including the Cross Kirkland Coordinator and the Redmond Central Connector. King County owns just over 16 miles of the Eastrail.

The Eastrail, much like all of our Regional Trails System trails, is a work in progress requiring constant management and upkeep. We always welcome constructive suggestion about trail maintenance, or safety from our users. Be sure to let us know if you see something on the trail that you think we can improve.

42 miles of continuous trail 

ERC Ownership Areas

Project Information Library:

Location: Renton to I-90

Status: In 2018 a four-mile section of soft surface trail was opened. The trail runs from Gene Coulon Park in Renton to Newcastle Beach Park in Bellevue, with connections at either end to the existing Lake Washington Loop Trail.

Future Activity:

Trail Construction by Washington State Dept. of Transportation (WSDOT) -  2019-2020: King County is working closely with WSDOT, who will construct a trail bridge over I-405 near Mercer Slough, replacing connectivity for bicycles and pedestrians in the Eastrail at the location of the former Wilburton train tunnel.The Wilburton tunnel once served as a freight train crossing over the southbound lanes of I-405, but was demolished in 2008 after freight operations had ceased on the Eastrail to facilitate expansion of the freeway at that time.

During its upcoming Renton to Bellevue Express Toll Lanes (R2B) project, WSDOT will construct a bicycle and pedestrian bridge to complete a missing gap in the Eastrail for trail. Also as part of the R2B project, WSDOT will construct 2.5 miles of paved trail in the Eastrail south of I-90 between Coal Creek Parkway and Ripley Lane. Anticipated to be in place by the end of 2020, this new segment of Eastrail trail replaces sections of the Lake Washington Loop trail that will be lost when the freeway is expanded through the area.

Location: I-90 to 108th Ave. NE

Status: In 2018 a one-mile section of soft surface trail opened from the south end of the Cross Kirkland Corridor at 108th Avenue Northeast to Northup Way.

Future Construction Update: Starting at Newcastle Beach Park, King County will construct the trail through Bellevue, eventually connecting to the Cross Kirkland Corridor. This section will require several major infrastructure projects, including: I-405 overpass (complete 2021), Wilburton Trestle rehabilitation (construction in 2021), NE 8th Street bridge (complete 2022).


Segment Overview:

Wilburton Segment and NE 8th St. Crossing Design (2017-2019) - The Wilburton Segment runs through Bellevue, and extends from the Cross Kirkland Corridor at 108th Ave. NE to I-90, including design of a direct connection to the I-90/Mountains to Sound Greenway Trail. This trail segment includes renovation of the historic Wilburton Trestle as a trail bridge while preserving the historic character of the structure, originally built in 1904. At nearly 1,000 feet long and over 100 feet off the ground the Wilburton Trestle is the largest timber train trestle in the Pacific Northwest and will be one of the most iconic elements of the Eastrail. Starting this fall we will be working on design of a trail bridge to cross over the busy NE 8th Street in Bellevue. 

Public Outreach:



Location: north Kirkland to Woodinville

Design/Construction Update: Where there are no plans for use of the railbed by our partner owners, Sound Transit and Puget Sound Energy, the Preferred Alternative is on the railbed where environmental impacts and costs are minimized. In some sections, such as from Slater Avenue in Kirkland to approximately 135th Avenue NE in Woodinville, the Preferred Alternative for the ERC’s Main Line is the Off-Railbed Alternative to avoid impacts to wetlands and to provide space for a Puget Sound Energy power line project. Other short sections in the Valley Segment are off railbed to avoid wetland and stream impacts, or to accommodate a short section of active freight operation in the northernmost mile of the Spur adjacent to SR202.
