TRAIL Under Construction!

The Eastside Rail Corridor (ERC) will connect rapidly growing East King County communities via a 42-mile multi-use trail in the right-of-way of an abandoned rail line.

Segments of the ERC in Redmond and Kirkland are already open, and it will be possible to explore a total of 13 miles by the end of 2017. By 2020, even more miles will be open!

Explore the map below to learn about progress on the corridor. Get the latest details by clicking the links to visit  webpages hosted by the public agencies building the corridor.

Redmond

x
The 4-mile ERC “spur” line in Redmond is owned and being developed in three phases by the City of Redmond. Known as the Redmond Central Connector (RCC), the trail is infused with open space that invites community gatherings, and art installations that give a nod to the historic rail use. One mile of hard surface trail opened in 2013 and runs through downtown Redmond. A second mile of the RCC, including a connection to the Sammamish River Trail, will open September 2017. The northernmost Redmond segment, which will connect the spur line to the main line near Woodinville, will also include an east/west connection to Kirkland. More Info

ERC to ELST Connection

x
King County is planning for a trail connection from its East Lake Sammamish Trail (ELST, 13 miles, from Redmond to Issaquah) to the Redmond Central Connector (RCC). East Link light rail service begins 2023 from the future downtown Redmond station, to be located adjacent to the Redmond Central Connector. The ELST to RCC connection will both connect people to transit and to other eastside communities, via Eastside Rail Corridor.

Kirkland

X
The 5.75 miles through Kirkland, known as the Cross Kirkland Corridor (CKC), is a mostly gravel interim trail. Since opening the trail in 2015, City of Kirkland has installed numerous local neighborhood access points along the trail. The CKC going through Kirkland’s Google campus is a hard surface trail that includes seating and various activity and play areas. The city has begun planning for the “Totem Lake Connector” pedestrian and bicycle bridge over NE 124th Street/Totem Lake Boulevard on the CKC; a pedestrian and bicycle bridge to connect the CKC to the South Kirkland Park & Ride and; an on-road connection between the CKC and the Redmond Central Connector (“spur” line) at Willows Rd. More Info

I-405 ERC Crossing

X
King County is working closely with WSDOT to plan and construct sections of the Lakefront segment, including the I-405 crossing. WSDOT will build an ERC trail crossing bridge over I-405, near the Mercer Slough, as part of their I-405 widening (“Bellevue Express Toll Lanes”) project. The new bridge will replace the former Wilburton train tunnel which once served as a freight train crossing over I-405, but was demolished in 2008 to facilitate expansion of the freeway at that time. More Info

Bellevue & Wilburton Trestle

X
Design for the entire Wilburton segment will be underway by King County as of fall 2017. Beginning at south Kirkland city limits, this ERC segment heads south through downtown Bellevue, terminating at the existing I-90 rail overpass in Bellevue’s Factoria area.

Once complete, the ERC trail in the Wilburton segment will create new bike and pedestrian trail connections in King County’s eastside and the region at-large. The ERC will help connect both Bellevue and Kirkland to Seattle via Northup Way and SR-520 trail, and to Redmond, via the SR-520 trail. The ERC segment through downtown Bellevue will involve several road crossings, including an overpass at NE 8th St, to connect people on the ERC to East Link light rail service at the trail-adjacent Wilburton Station. A connection to the I-90 corridors Mountains to Sound Greenway will also be a part of this ERC section.

The Wilburton Trestle, the longest wooden railroad trestle in the Pacific Northwest, will be retrofitted to accommodate the ERC trail atop the trestle. More Info

Woodinville

X
The 2.6-mile segment of the ERC in Woodinville is owned by the City of Woodinville. They plan to develop the ERC over the next several years.

Valley Segment

X
The 7-mile Valley segment is part of the 17 miles of ERC right-of-way owned by King County. King County has future plans to build a trail through the Valley segment between south Woodinville and north Kirkland on the mainline and between south Woodinville and north Redmond on the spur line. More Info

Snohomish

X
In Snohomish County the ERC rail line extends 12 miles, terminating at the City of Snohomish. Snohomish County is designing for “trail plus rail” in the ERC right of way. The trail will be known as the Centennial Trail South, and will connect from the King/Snohomish county border to the existing 29-mile long Centennial Trail in the City of Snohomish. The Centennial Trail runs through the cities of Snohomish, Lake Stevens, and Arlington, and into Skagit County. More Info

Lakefront Trail

X
A 4-mile segment of the ERC Lakefront segment, from Newcastle Beach Park in Bellevue to Gene Coulon Park in Renton will open by the end of 2017 in an interim gravel state, with connections at either end to the existing Lake Washington Loop Trail. This area is part of the 17 miles of ERC right-of-way owned by King County. By 2020 the trail in this area between Coal Creek Parkway and Ripley Lane will be upgraded to paved trail by WSDOT to replace sections of the Lake Washington Loop trail that will be lost when the freeway is expanded through the area. More Info

Kirkland to Bellevue

X
A one-mile section of the ERC, from the Cross Kirkland Corridor at 108th Ave NE to Northup Way, will open by the end of 2017 as an interim gravel trail. This area is part of the 5-mile Wilburton segment of the ERC owned by King County.

Just south of here is a one-mile segment of the ERC owned by Sound Transit, which is adjacent to the site of the future East Link light rail maintenance yard. In this segment of the ERC, adjacent trail and light rail tracks are planned. During light rail construction (through 2023) an interim trail will bypass this segment of the ERC via a shared use path on 120th Ave NE. More Info
The end-to-end trail will join Renton to Snohomish, via Woodinville, Kirkland and Bellevue, with a spur trail to Redmond. Running through the economic hearts of five of the Eastside's largest cities, it's hard to overstate the mobility and outdoor recreation impacts of the future Eastside Rail Corridor.  Momentum is building and work is already underway...

With multiple owners, the the ERC is being planned and developed in numerous segments, with close coordination among public owners and stakeholders in order to create a cohesive end-to-end trail user experience. Explore the map below to learn more about the trail.

Trail owners and stakeholders have adopted a multi-use vision for the corridor.
In addition to an end-to-end trail, transit is planned in some portions of the corridor. The ERC is also a significant utility corridor. Kirkland’s long-term vision of the Cross Kirkland Corridor is trail plus bus rapid transit. In the segment owned by Sound Transit, a trail will run parallel to East Link light rail for one mile. The Snohomish section of the corridor will incorporate both heavy rail and a trail, and that is also a potential alignment in the northern King County segment through Woodinville.
