Interstate 5 (I-5) is the main north–south Interstate Highway on the West Coast of the United States, running largely parallel to the Pacific coast of the contiguous U.S. from Mexico to Canada. It travels through the states of California, Oregon, and Washington, serving several large cities on the U.S. West Coast, including San Diego, Los Angeles, Sacramento, Portland, and Seattle. It is the only continuous Interstate highway to touch both the Mexican and the Canadian borders. Upon crossing the Mexican border at its southern terminus, I-5 continues to Tijuana, Baja California, as Mexico Federal Highway 1 (Fed. 1). Upon crossing the Canadian border at its northern terminus, it continues to Vancouver as British Columbia Highway 99 (BC 99).
The Willamette River is a major tributary of the Columbia River, accounting for 12 to 15 percent of the Columbia's flow. The Willamette's main stem is 187 miles (301 km) long, lying entirely in northwestern Oregon in the United States. Flowing northward between the Oregon Coast Range and the Cascade Range, the river and its tributaries form the Willamette Valley, a basin that contains two-thirds of Oregon's population, including the state capital, Salem, and the state's largest city, Portland, which surrounds the Willamette's mouth at the Columbia.
The Steel Bridge is a through truss, double-deck vertical-lift bridge across the Willamette River in Portland, Oregon, United States, opened in 1912. Its lower deck carries railroad and bicycle/pedestrian traffic, while the upper deck carries road traffic, and light rail (MAX), making the bridge one of the most multimodal in the world. 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 Old Town Chinatown neighborhood in the west.
The Historic Columbia River Highway is an approximately 75-mile-long (121 km) scenic highway in the U.S. state of Oregon between Troutdale and The Dalles, built through the Columbia River Gorge between 1913 and 1922. As the first planned scenic roadway in the United States, it has been recognized in numerous ways, including being listed on the National Register of Historic Places, being designated as a National Historic Landmark by the U.S. Secretary of the Interior, being designated as a National Historic Civil Engineering Landmark by the American Society of Civil Engineers, and being considered a "destination unto itself" as an All-American Road by the U.S. Secretary of Transportation. The historic roadway was bypassed by the present Columbia River Highway No. 2 from the 1930s to the 1950s, leaving behind the old two-lane road. The road is now mostly owned and maintained by the state through the Oregon Department of Transportation as the Historic Columbia River Highway No. 100 or the Oregon Parks and Recreation Department as the Historic Columbia River Highway State Trail.

The Fremont Bridge is a steel tied-arch bridge over the Willamette River located in Portland, Oregon, United States. It carries Interstate 405 and US 30 traffic between downtown and North Portland where it intersects with Interstate 5. It has the longest main span of any bridge in Oregon and is the second longest tied-arch bridge in the world. The bridge was designed by Parsons, Brinckerhoff, Quade and Douglas, and built by Murphy Pacific Corporation.
The Marquam Bridge is a double-deck, steel-truss cantilever bridge that carries Interstate 5 traffic across the Willamette River south of downtown Portland, Oregon. It is the busiest bridge in Oregon, carrying 140,500 vehicles a day as of 2016. The upper deck carries northbound traffic; the lower deck carries southbound traffic.
The Ross Island Bridge is a cantilever truss bridge that spans the Willamette River in Portland, Oregon. It carries U.S. Route 26 across the river between southwest and southeast Portland. The bridge opened in 1926 and was designed by Gustav Lindenthal and honors Oregon pioneer Sherry Ross. It is named for its proximity to Ross Island. Although it looks like a deck arch bridge, it is a cantilever deck truss bridge, a rare type in Oregon.
The Interstate Bridge is a pair of nearly identical steel vertical-lift, "Parker type" through-truss bridges that carry Interstate 5 traffic over the Columbia River between Vancouver, Washington and Portland, Oregon in the United States.
The Oregon City Bridge, also known as the Arch Bridge, is a steel through arch bridge spanning the Willamette River between Oregon City and West Linn, Oregon, United States. Completed in 1922, it is listed on the National Register of Historic Places. It was built and is owned by the Oregon Department of Transportation (ODOT) as part of Oregon Route 43 and is the third-southernmost Willamette bridge in the Portland metropolitan area, after the Boone Bridge in Wilsonville and the Oregon 219 bridge near Newberg.
Oregon Route 99E Business is a business route through Salem, Oregon for Oregon Route 99E, which bypasses downtown via Interstate 5 (I-5). A portion of this highway was originally planned to be a freeway, signed as Interstate 305; however the proposed freeway was cancelled after community opposition.
Oregon Route 43 is an Oregon state highway that runs between the cities of Oregon City and Portland, mostly along the western flank of the Willamette River. While it is technically known by the Oregon Department of Transportation as the Oswego Highway No. 3, on maps it is referred to by its route number or by the various street names it has been given.
In the U.S. state of Oregon, U.S. Route 30, a major east–west U.S. Highway, runs from its western terminus in Astoria to the Idaho border east of Ontario. West of Portland, US 30 generally follows the southern shore of the Columbia River; east of Portland the highway has largely been replaced with Interstate 84, though it is signed all the way across the state, and diverges from the I-84 mainline in several towns, as a de facto business route. Out of all the states U.S. Route 30 traverses, it spends the most time in Oregon. At 477 miles, it is also the longest road in the state.
Harbor Drive is a short roadway in Portland, Oregon, functioning mainly as a ramp to and from Interstate 5. It was once much longer, running along the western edge of the Willamette River in the downtown area. Most of the road was replaced with Tom McCall Waterfront Park in the 1970s. Signed as U.S. Route 99W, it had been the major route through the city and its removal is often cited as the first instance of freeway removal in the U.S. and as a milestone in urban planning.
Historic ferries in Oregon are water transport ferries that operated in Oregon Country, Oregon Territory, and the state of Oregon, United States. These ferries allowed people to cross bodies of water, mainly rivers such as the Willamette in the Willamette Valley, and the Columbia, in order to transport goods, move people, and further communications until permanent bridges were built to allow faster crossing of the water. The early ferries were used by wagons and pedestrians, while later ones transported trains and then automobiles. Oregon has a few automobile ferries still in operation.
Boone Bridge is a steel girder highway bridge over the Willamette River at Wilsonville, Oregon, in the United States. Built in 1954, it crosses the river to the Charbonneau section of Wilsonville, carrying Interstate 5 into the open Willamette Valley from the Portland metropolitan area. Maintained by the Oregon Department of Transportation, the 1,111-foot-long (339 m) bridge has three travel lanes in each direction. To the west is the site of the former Boone's Ferry, which the bridge replaced.
Burlington Northern Railroad Bridge 9.6 or BNSF Railway Bridge 9.6, also known as the Columbia River Railroad Bridge, is through truss railway bridge across the Columbia River, between Portland, Oregon, and Vancouver, Washington, owned and operated by BNSF Railway.

It is concurrent with U.S. Route 30 (US 30) for most of its length and runs 376 miles (605 km) from an interchange with I-5 in Portland to the Idaho state line near Ontario. The highway roughly follows the Columbia River and historic Oregon Trail in northeastern Oregon, and is designated as part of Columbia River Highway No. 2 and all of the Old Oregon Trail Highway No. 6; the entire length is also designated as the Vietnam Veterans Memorial Highway. I-84 intersects several of the state's main north–south roads, including US 97, US 197, I-82, and US 395.
