Architecture of Portland, Oregon; List of tallest buildings in Portland, Oregon; and Downtown Portland
Portland's cityscape derives much of its character from the numerous bridges that span the Willamette River downtown, several of which are historic landmarks, and Portland has been nicknamed "Bridgetown" for many decades as a result. Three of downtown's most heavily-utilized bridges are more than 100 years old and are designated historic landmarks: Hawthorne Bridge (1910), Steel Bridge (1912), and Broadway Bridge (1913). Portland's newest bridge in the downtown area, Tilikum Crossing, opened in 2015 and is the first new bridge to span the Willamette in Portland since the 1973 opening of the double-decker Fremont Bridge.
Other bridges that span the Willamette river in the downtown area include the Burnside Bridge, the Ross Island Bridge (both built 1926), and the double-decker Marquam Bridge (built 1966). Other bridges outside the downtown area include the Sellwood Bridge (built 1925) to the south; and the St. Johns Bridge, a Gothic revival suspension bridge built in 1933, to the north. The Glenn L. Jackson Memorial Bridge and the Interstate Bridge provide access from Portland across the Columbia River into Washington state.
