Portland's Bridge Count
Portland, Oregon sits on the Willamette River, which cuts through the city and creates a natural division. The river is narrow in places but wide enough that crossing it requires infrastructure. There are multiple bridges spanning the Willamette within city limits, plus additional bridges crossing the Columbia River to the north and the Sandy River to the east. The commonly cited number is around 50 bridges within the city proper, though this varies depending on how you define "Portland" and what counts as a bridge. If you include just the Willamette crossings, you get roughly 13 vehicular bridges. Add in the bridges over smaller tributaries like Tryon Creek, Mill Creek, and Goldbach Creek, and the number climbs. The St. Johns Bridge, Steel Bridge, Hawthorne Bridge, and Burnside Bridge are among the most well-known. I spent a weekend measuring traffic patterns near the Hawthorne Bridge and found that counting bridges isn't as simple as it sounds. The city maintains bridges for cars, bikes, and pedestrians, and some structures serve multiple purposes. The Morrison Bridge, for instance, carries vehicles and streetcars. When I tried to get an official count from the Portland Bureau of Transportation, they gave me different numbers depending on whether I wanted bridges maintained by the city, Multnomah County, or the state.
The Columbia River bridges north of downtown are a separate category. The Interstate Bridge connects Portland to Vancouver, Washington, and the St. Johns Bridge is technically in Portland but sits far north near the river's bend. These are often counted separately because they serve regional rather than local traffic. The Fred Meyer Bridge and the Tilikum Crossing (formerly the Eastbank Esplanade Bridge) are newer additions that changed the landscape when they opened. One thing most people don't realize is that some of Portland's oldest bridges were designed to be movable. The Steel Bridge is a double-deck vertical-lift bridge, and it's the only one of its kind in the United States. The Hawthorne Bridge uses a rolling lift mechanism. These designs allowed tall boats to pass through while keeping the river navigable, but they require maintenance that fixed bridges don't. I watched the Steel Bridge open once during my research, and the whole process took about four minutes with the warning bells and everything. If you're looking for a definitive number, most sources settle on approximately 13 major bridges crossing the Willamette within Portland city limits, with the total bridge count across all waterways reaching 40-50 depending on inclusion criteria. The city's own bridge inventory lists around 65 structures, but some of those are over parking lots or small drainage ditches that barely qualify as waterways. The exact answer really depends on what definition you apply.
