Shot from the seat of my recumbent trike on the Green River Trail in Tukwila, Washington. Overhead is Tukwila International Boulevard. The highway used to be called “Pacific Highway South” but in 1998 it was changed for political reasons. At one time it also carried the “State Route 99” label.

Why is the Green River Trail following the Duwamish River? At a confluence upstream from here, the Green becomes the Duwamish. The Duwamish River flows leftward into Elliott Bay in Seattle, a body of salt water. Thus the river is affected by tides. When I took this picture, the tide was coming in. The upstream flow was strong enough to create little eddies along the edge. I sat here for a few minutes watching the river flow.

Google Earth and Wikimapia label the highway with both names. Bing Maps still calls it “Pacific Highway South.” The Thomas Guide “King, Snohomish, and Pierce Counties Street Guide” label it with its current name.
