The route drawn on this API map is an approximation of the route that I rode. Google API Maps will not draw a DRIVING mode route from Newhalem to Winthrop along WA20 during the winter because the road is closed, they may(?) show that route during summer months however the DRIVING mode route can be dragged to WA20. This map was drawn using the BICYCLING mode. Click on North Cascades Highway to get an open/closed status for the route.
