The other Young's Bay bridge (the old bridge) will get you there, but it ends on a slower road off the beaten path. These days, it's mostly used by people who live or work in that area. I posted a photo of its artistic design here.
An aerial photo by Frank Wolfe shows the New Young's Bay Bridge (left) and the Astoria-Megler bridge (right). The old Young's bay bridge is out of the photo on the left.
