 Reconstructions of US 101 in the post-World War II era shortened distances and eliminated the worst narrow curvy sections in various places on the Oregon Coast.Entering Washington State at the north end of the Astoria–Megler Bridge west of Megler at the intersection with SR 401, US 101 follows the northern banks of the Columbia River until Ilwaco.At this point it turns to the northeast and follows the shore of Willapa Bay and the Willapa River as far as Raymond, from which it proceeds directly north to Aberdeen, offering access from this city into the Olympic National Park.
