The Cross Kirkland Corridor Reopened in February. That Wasn't the End of the Story.
If you walk, run, or bike the Cross Kirkland Corridor and you think the trail is back to normal, you're only half right. The section between NE 52nd Street and 108th Avenue NE did reopen, back on February 23. But the equipment that fixed the emergency never left. It's still staged along the west side of the trail right now, in September, waiting for a second phase of work that was baked into the plan from the start. And while that's happening, a completely separate project is also cutting into the corridor a few blocks away. Two disruptions, two different causes, running on overlapping timelines. If your mental model is "the trail had a problem, the problem got fixed," you're missing the actual shape of this year.
Here's what happened, in order, and what's still unresolved.
The Cross Kirkland Corridor sits on top of infrastructure most residents never consider while they're jogging past Google's Kirkland campus or stopping at Chainline Brewing for a post-ride pint. Running beneath the packed gravel is the Eastside Interceptor Section 14, a King County sewer pipe seven feet in diameter that carries an average of 10 million gallons of wastewater a day during dry weather, on its way to the county's South Treatment Plant in Renton.
In late July 2025, King County and City of Kirkland crews detected a leak from that pipe entering Kirkland's piped stream. County officials coordinated with Public Health, Seattle & King County, and no public health risk was identified, but the leak was serious enough that in September 2025 King County's Department of Natural Resources and Parks issued a Declaration of Urgency to speed up repairs. The City of Kirkland followed with its own Proclamation of Emergency. That's not routine maintenance language. That's the vocabulary local government uses when a fix can't wait for the normal permitting calendar.
To keep sewer service running to homes and businesses while crews worked, King County installed a temporary above-ground pipe, 3,000 feet long and 18 inches in diameter, alongside the trail. Wastewater was diverted into it starting in mid-January 2026. The trail itself closed between NE 52nd Street and 108th Avenue NE starting as early as January 5, and stayed closed through the worst of the underground work.
The reopening came on February 23, 2026, and King County's public messaging at the time was straightforward: pipe repair complete, trail opening soon. If you only read that headline, you'd assume the story ended there.
It didn't. The same notice that announced the reopening also flagged that some equipment would remain along the trail for summer repair work. That sentence is the whole thesis of this post. The county wasn't just wrapping up. It was pausing between phases.
On March 24, King County closed the same stretch again, this time for one day, to test soil conditions ahead of the summer repair work the February notice had already warned about. The trail reopened that same evening at 5 p.m., but the underlying plan stayed on schedule: crews would return in summer to stabilize and repair a rockery wall and a culvert located beneath the pipe.
That work is what's happening now, and it's why the temporary above-ground pipe and the excavated access points are still sitting on the west side of the trail as of this writing. The access points are covered with steel plates and fenced off, not because anyone forgot to clean up, but because they're staged for the return of construction crews. Once the culvert repairs are finished, the county says the equipment comes out and new trees go in. There's no published date yet for that final step, which means the honest answer to "when does this fully wrap up" is still "sometime after summer repairs conclude," not "already done."
Here's the part that catches even attentive residents off guard. The city's own Cross Kirkland Corridor closures page currently lists two separate causes for active closures on the trail: King County's urgent Eastside Interceptor repair, which is the saga above, and the construction of a new NE 85th Street shared-use pathway, which is its own project with its own timeline.
These aren't the same construction crew, the same funding source, or the same completion date. They just happen to be running in the same corridor at the same time, which means a resident checking the trail's status this fall needs to know which section they're dealing with, not just whether "the trail" in the abstract is open. A closure near 108th Avenue NE tells you nothing about whether the NE 85th Street crossing is passable, and vice versa.
The Cross Kirkland Corridor is 5.75 miles of crushed gravel path running from the South Kirkland Park and Ride north through the Totem Lake Business District, the first improved segment of what will eventually become the 42-mile Eastrail connecting Renton to Snohomish County. It's popular for a reason. It's flat, wide enough for strollers and wheelchairs, and it threads past genuine landmarks: the Google campus stretch south of Totem Lake, Chainline Brewing directly on the route, and a mix of light industrial land and quiet woods depending on which mile marker you're at.
A few things worth knowing before you plan a route this month:
None of this means the Cross Kirkland Corridor is unusable. Thousands of residents still walk, run, and bike it every week, and most of the 5.75 miles have nothing to do with either active project. But if you've been avoiding a section because you heard it was "closed" back in January, or assuming everything's settled because you saw a reopening notice in February, both of those mental models are outdated. The realistic read on September 2026 is that this is a corridor in extended, overlapping repair, not a finished one. Knowing which few hundred feet are actually affected, and why, is the difference between a five-minute detour and turning around at a fence you didn't expect.
If you want the corridor to feel simple again, the county's own updates are the most reliable place to track it, not word of mouth from a neighbor who walked it once in March.
