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.

Location: Renton to I-90

Status: Starting in June 2020, and lasting into May 2021, 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 LaneView 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.

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:



King County Parks will begin removing railroad rails in December 2020 to make way for 2.5 miles of new Eastrail that will connect Kirkland to Woodinville. Rail removal will occur in December and January, with trail construction complete by the end of summer 2021. This December/January work will not include rail removal at any driveway or road crossings. View a map of the future trail segment.

This new Eastrail section will continue north from the end of the Cross Kirkland Corridor to NE 145th in Woodinville near the Chateau Ste. Michelle winery. A new trail crossing at NE 145th will be built by the City of Woodinville allowing connections to the Sammamish River Trail. 

This new section includes Kirkland’s Willows Road Regional Trail Connection, which is already under construction.

King County is committed to developing trail in all areas where rail is being removed; however, several miles of the rail removal will not be turned into trail in 2021.
