This trail connects the Spokane Centennial Trail (near the Washington/Idaho border) - and Appleway Road in Liberty Lake Washington.
It is possible to ride along the shoulders of Appleway - all the way from Spokane Bridge Road into Liberty Lake, but the Eastern end of Appleway isn't really bike/trike friendly. It has narrow-to-non-existent shoulders. It's not anywhere near flat. And, is a fairly heavily traveled road (for two lanes.)
This trail bypasses the two-lane portion and connects the Centennial Trail with Appleway near where the road widens into four-lane. The remaining section of Appleway into Liberty Lake is quite bike/trike friendly.
That's my two cents.
