Context

The Columbia forms the OR/WA border for 480 km. Portland sits at the Willamette–Columbia confluence. "Reaching the Columbia" from Portland usually means crossing the bridge to Vancouver's waterfront or driving east to less-developed access points. No ferry needed—bridges span the main channel.
