The way points of this bicycle route:
Here is where the Interurban and Green River meet in Kent. They meet again in Tukwila at Interurban Ave and I405. I usually park further south on the Interurban, but I wanted to see how long the loop part is.
Cross Green River, Exit InterUrban trail, join Green River Trail
You can cross the river here and ride on the west side (Frager Road) to 212th or 200th and cross back.
There's a bridge here, connecting the Interurban trail to the Green River Trail!
