The city of Portland, Oregon, contains many bridges over various geographical features and roads of varying lengths and usages. Some bridges carry roads, some carry pedestrians only, some carry trains only, and others have various restrictions.
Bridges over the Willamette River comprise a majority of the notable bridges in the city. Portland has 12 bridges that span the Willamette, while only two road bridges cross the Columbia River, and other notable bridges cross roads, canyons or other bodies of water. Interstate 5 crosses the Willamette via the Marquam Bridge and the Columbia via the Interstate Bridge. Due to the large number of bridges crossing the Willamette in the center of town, Portland's nicknames include "Bridge City" and "Bridgetown."
