Courtesy Seattle Bike Blog, King County announced a 100% closure with NO POSTED DETOUR on the Sammamish River Trail from 143rd to 145th on October 13th. They hope it will only be for a couple of hours, but could be multiple days.
This is an extremely difficult place to pull this kind of trick, as that’s not just along the river but private property farmland, and the few roads nearby are also under construction.
So here’s my route:
If you’re going all the way to Redmond from the north or to Woodinville from the south, I would take Redmond Central Connector and Eastrail, transferring over over to/from Sammamish River via the connector trail on the north side of 145th.
That adds some distance but it’s near-zero car interaction and both RCC and Eastrail are fine routes. Yes, Eastrail is gravel, but it’s hardpack gravel and no more difficult to ride than asphalt. Seriously: it’s fine.
Naturally, I have prepared a map:
