The Hawthorne Bridge is a truss bridge with a vertical lift that spans the Willamette River in Portland, Oregon, joining Hawthorne Boulevard and Madison Street. It is the oldest vertical-lift bridge in operation in the United States and the oldest highway bridge in Portland. It is also the busiest bicycle and transit bridge in Oregon, with over 8,000 cyclists and 800 TriMet buses (carrying about 17,400 riders) daily. It was added to the National Register of Historic Places in November 2012.

The Steel Bridge is a through truss, double-deck vertical-lift bridge across the Willamette River in Portland, Oregon, United States, opened in 1912.

It is the only double-deck bridge with independent lifts in the world and the second oldest vertical-lift bridge in North America, after the nearby Hawthorne Bridge. The bridge links the Rose Quarter and Lloyd District in the east to the Old Town Chinatown area in the west.

Known in recent decades as the site of several large paper mills on the Willamette River, the city played a significant role in the early history of the Oregon Country. It was established by Hudson's Bay Company's Dr. John McLoughlin in 1829 near the confluence of the Clackamas River with the Willamette to take advantage of the power of Willamette Falls to run a timber mill. During the 1840s and 1850s, it was the destination for those wanting to file land claims after travelling the Oregon Trail as the last stop on the trail. It was the capital of the Oregon Territory from its establishment in 1848 until 1851 and rivalled Portland for early supremacy in the area. In 1846, the city's newspaper, the Oregon Spectator, was the first American newspaper to be published west of the Rocky Mountains. Oregon City was the site of the Beaver Coins Mint, producing the short-lived independent Oregon Territory currency in 1849.

George Rogers Park is Lake Oswego's first community park and one of its most diverse. Situated on the Willamette River, the park is the site of significant Native American activity over 10,000 years ago. In the early 19th century, the river landing at the mouth of Oswego Creek was a convenient camping place for explorers, fur traders, and pioneers. In the words of a Lake Oswego resident, it was "a stopping place, a sort of relay station for boats both large and small, plying up and down the river between Astoria and Champoeg."

The Willamette Falls is a horseshoe-shaped block waterfall caused by a basalt shelf in the river bottom. The 42-foot-high and 1,500-foot-wide falls occurs 26 river miles upstream from the Willamette's confluence with the Columbia River. It's the largest waterfall by water volume in the Northwest and the 18th largest by volume. Around the falls are the locks, which are the oldest continuously operating multi-lift lock and canal system in the United States.

The Clackamas River is located to the west of the Cascade Range and to the south of the Columbia River Gorge in northern Oregon. Flowing northwest from its sources high in the Cascade Mountains, the designated portion of the river, which is 47 miles (75.6 km) in length, runs from Big Spring (headwaters area) to Big Cliff, just south of the town of Estacada. This most picturesque region is entirely within the Mt. Hood National Forest and encompasses forested lands, wetlands, riparian areas and rock cliffs.

Portland Parks & Recreation's Oaks Bottom Wildlife Refuge is a 163-acre complex of meadows, woodlands, and wetlands in Portland on the east bank of the Willamette River, just north of the Sellwood Bridge.

Governor Tom McCall Waterfront Park is a 36.59-acre (148,100 m2) park located in city centre Portland, Oregon, along the Willamette River. After the 1974 removal of Harbour Drive, a major milestone in the motorway removal movement, the park was opened to the public in 1978. The park covers 13 tax lots and is owned by the City of Portland (Portland Parks and Recreation). The park was renamed in 1984 to honour Tom McCall, the Oregon governor who pledged his support for the beautification of the west bank of the Willamette River—harkening back to the City Beautiful plans at the turn of the century which envisioned parks and greenways along the river. The park is bordered by RiverPlace to the south, the Steel Bridge to the north, Naito Parkway to the west, and Willamette River to the east. In October 2012, Waterfront Park was voted one of America's ten greatest public spaces by the American Planning Association.
