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 Corridor and the Redmond Central Connector. King County owns just over 16 miles of the Eastrail.

Project Information Library:

Location: Renton to I-90

Status: Starting in June 2020, and lasting into early 20201, areas of this four-mile trail section will be closed to construct 2.5 miles of new paved trail between Coal Creek Parkway and Ripley Lane. View map and timeline of construction.

Trail Construction by Washington State Dept. of Transportation (WSDOT) -  2020 2021: Starting June 2020 construction of 2.5 miles of paved Eastrail between Coal Creek Parkway and Ripley Lane will begin. The new, wider trail will offer more space between people walking and biking, and replace sections of the Lake Washington Loop Trail that will be removed during future I-405 construction. This trail work is a joint effort of the WSDOT and King County Parks, and is being performed by the project’s contractor, Flatiron-Lane Joint Venture.

On June 22 the first section of trail (Ripley Lane N to Hazelwood Lane SE) will be closed until mid-September. The Lake Loop trail which parallels this section will remain open.

If you have any questions about this construction please contact:

In 2021, as part of the same WSDOT I-405 work, a trail bridge over I-405 near Mercer Slough will be built. This new bridge will provide essential connectivity for bicycles and pedestrians 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.

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: 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 (construction 2021), Wilburton Trestle rehabilitation (open 2023), NE 8th Street bridge (open 2022). 

Public Outreach:



Starting 2021 King County will partner with Kirkland and Woodinville to build trail from the north end of the Cross Kirkland Connector to Woodinville. The gravel trail will include Kirkland’s Willlows Connector and then will head north to 145th in Woodinville. View our interactive map to see the details.
