On my recent trip to Oregon, I planned to show my wife and great friends all that it's coast had to offer. In order to do that, one has to start in Astoria. Astoria is the most northern city near the coast and is situated fourteen miles from the mouth of the Columbia River at the Pacific Ocean. The Columbia River acts as the "state line" between Oregon and Washington. Thus, the only way to drive to Washington is via bridges. The Astoria-Megler Bridge is the longest bridge that spans the river. The four mile bridge is, in fact, the longest continuous truss bridge in North America.
