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 [1] and the oldest highway bridge in Portland. It is also the busiest bicycle bridge in Oregon, with over 8,000 cyclists [4] and 800 TriMet buses (carrying about 17,400 riders) daily. [1] It was added to the National Register of Historic Places in November 2012. [3] [5]
The bridge consists of five fixed spans and one 244-foot-long (74 m) vertical-lift span. It is 1,382 feet (421 m) in total length. [1] The bridge was originally 63 feet (19 m) wide, [6] including two five-foot sidewalks, but the sidewalks were widened to 10 feet in 1998, increasing the structure's overall width to 73 feet (22 m). [1] The 880,000-pound (400,000 kg) counterweights are suspended from the two 165-foot-tall (50 m) towers. [1] It is operated by a pair of 150-horsepower motors. [7] On average, the lift span is raised for river traffic 120 times per month. [1] : 62 While the river is at low level, the bridge is 49 feet (15 m) above the water, causing it to be raised an average of 200 times per month. As of 2001, the average daily traffic was 30,500 vehicles. The bridge was designed by Waddell & Harrington, which also designed the Steel and Interstate bridges. [1] [8] John Alexander Low Waddell invented the modern-day vertical-lift bridge. [1]
The current bridge was built to replace the second Madison Street Bridge, a wooden bridge built in 1900. It cost $511,000 to build [9] and was opened on December 19, 1910. [1] [10] Hawthorne Boulevard (and thus the bridge) was named after Dr. J.C. Hawthorne, the cofounder of Oregon's first mental hospital and early proponent for the first Morrison Bridge. [1]
The streetcar tracks across the bridge were originally in the outer lanes, [11] but were relocated to the center lanes in 1931. [12] The deck was changed from wood to steel grating in 1945. [1]
In 1985, the lift span sheaves, the grooved wheels that guide the counterweight cables, were replaced. The bridge went through a $21 million renovation from 1998 to 1999, which included replacing the steel grated deck and repainting. [1] [13] The original lead-based paint was completely removed and replaced with 3 layers of new paint that is estimated to last 30 years. [14] During this upgrade, the sidewalks were widened to 10 feet (3.0 m), making it a thoroughfare for bicycle commuters. Due to the replacement of the steel deck during this project, the channels which used to carry the rails for streetcars and interurban trains were also removed. The bridge was closed for one year to permit the renovation to be carried out. [1]
The original color of the bridge was black, lasting until 1964, when it was repainted yellow-gold ochre. [15] During the 1998–99 renovation, the color was changed to green with red trim. [1]
In 2001, the sidewalks were connected to the Eastbank Esplanade. In 2005, the estimated cost to replace the bridge was $189.3 million. [16]
The 2003 film, The Hunted , included a scene set on MAX on the Hawthorne Bridge. Since MAX does not cross the bridge, the movie company connected two articulated buses remodeled to resemble a MAX train, complete with fake overhead lines and a sprinkler system to simulate rain. [17] [18] Light-rail (interurban) service did cross the Hawthorne Bridge until 1956. [19]
The new deck put in place in the outer lanes during the 1998–99 renovation was designed to be strong enough for possible use by modern, heavier streetcars or light rail trains in the future, [20] [21] which was proposed at that time, [20] and TriMet was still considering a Hawthorne Bridge routing for its future MAX Orange Line, to Milwaukie, in 2002. [22] However, following the transit agency's later decision to build the Tilikum Crossing for the Milwaukie MAX line, which bridge could also be used by the Portland Streetcar, [23] it became unlikely that rail cars will ever again cross the Hawthorne Bridge.
The bridge was added to the National Register of Historic Places [24] in November 2012. [5]
In August 2012, an automated real-time bicycle counter was installed on the bridge, the first such counter to be installed in a U.S. city. [25] [26] It was purchased by the non-profit group Cycle Oregon for $20,000 and donated to the city. [27] [28] The city paid $5,000 for its installation. [29] The millionth rider was counted in July 2013. [30] The counter was broken in 2018 and has not been repaired; no data has been recorded since. [31]
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 Metropolitan Area Express (MAX) is a light rail system serving the Portland metropolitan area in the U.S. state of Oregon. Owned and operated by TriMet, it consists of five lines connecting the six sections of Portland; the communities of Beaverton, Clackamas, Gresham, Hillsboro, Milwaukie, and Oak Grove; and Portland International Airport to Portland City Center. Trains run seven days a week with headways of between 30 minutes off-peak and three minutes during rush hours. In 2019, MAX had an average daily ridership of 120,900, or 38.8 million annually. Due to the COVID-19 pandemic, which impacted public transit use globally, annual ridership plummeted, with only 14.8 million riders recorded in 2021.
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 Burnside Bridge is a 1926-built bascule bridge that spans the Willamette River in Portland, Oregon, United States, carrying Burnside Street. It is the second bridge at the same site to carry that name. It was added to the National Register of Historic Places in November 2012.
The Morrison Bridge is a bascule bridge that spans the Willamette River in Portland, Oregon. Completed in 1958, it is the third bridge at approximately the same site to carry that name. It is one of the most heavily used bridges in Portland. It was added to the National Register of Historic Places in November 2012.
The Marquam Bridge is a double-deck, steel-truss cantilever bridge that carries Interstate 5 traffic across the Willamette River from south of downtown Portland, Oregon, on the west side to the industrial area of inner Southeast on the east. 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 Marquam also has on and off ramps for Interstate 405 on the south end of the bridge, while the terminus on the east bank of the river is near the interchange with Interstate 84.
The Broadway Bridge is a Rall-type bascule bridge spanning the Willamette River in Portland, Oregon, United States, built in 1913. It was Portland's first bascule bridge, and it continues to hold the distinction of being the longest span of its bascule design type in the world. It was added to the National Register of Historic Places in November 2012.
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 through-truss bridges that carry Interstate 5 traffic over the Columbia River between Vancouver, Washington and Portland, Oregon in the United States.
The Sellwood Bridge is a deck arch bridge that spans the Willamette River in Portland, Oregon, in the United States. The current bridge opened in 2016 and replaced a 1925 span that had carried the same name. The original bridge was Portland's first fixed-span bridge and, being the only river crossing for miles in each direction, the busiest two-lane bridge in Oregon.
The BNSF Railway Bridge 5.1, also known as the St. Johns Railroad Bridge or the Willamette River Railroad Bridge, is a through truss railway bridge with a vertical lift that spans the Willamette River in Portland, Oregon, United States. Built by the Spokane, Portland and Seattle Railway (SP&S) and completed in 1908, it was originally a swing-span bridge, and its swing-span section was the longest in the world at the time. However, 81 years later the main span was converted from a swing-type to a vertical-lift type, in order to widen the navigation channel. The lift span is one of the highest and longest in the world. The bridge consists of five sections, with the two sections closest to the bank on each side fixed.
Interstate 205 (I-205) is an auxiliary Interstate Highway in the Portland metropolitan area of Oregon and Washington, United States. The north–south freeway serves as a bypass route of I-5 along the east side of Portland, Oregon, and Vancouver, Washington. It intersects several major highways and serves Portland International Airport.
Like transportation in the rest of the United States, the primary mode of local transportation in Portland, Oregon is the automobile. Metro, the metropolitan area's regional government, has a regional master plan in which transit-oriented development plays a major role. This approach, part of the new urbanism, promotes mixed-use and high-density development around light rail stops and transit centers, and the investment of the metropolitan area's share of federal tax dollars into multiple modes of transportation. In the United States, this focus is atypical in an era when automobile use led many areas to neglect their core cities in favor of development along interstate highways, in suburbs, and satellite cities.
Portland is "an international pioneer in transit orientated developments."
The MAX Orange Line is a light rail line serving the Portland metropolitan area in the U.S. state of Oregon. Operated by TriMet as part of the MAX Light Rail system, it connects Portland City Center, Portland State University (PSU), Southeast Portland, Milwaukie, and Oak Grove. The line serves 17 stations and runs for 201⁄2 hours per day with headways of up to 15 minutes. It averaged 3,480 daily weekday riders in September 2020.
The Wapato Bridge, formerly known as the Sauvie Island Bridge, crosses the Multnomah Channel of the Willamette River near Portland, Oregon, United States. The original Parker truss bridge, built in 1950 with a 200-foot (61 m) main span, was replaced with a tied arch bridge with a 360-foot (110 m) span in 2008 due to cracks discovered in 2001.
Tilikum Crossing, Bridge of the People is a cable-stayed bridge across the Willamette River in Portland, Oregon, United States. It was designed by TriMet, the Portland metropolitan area's regional transit authority, for its MAX Orange Line light rail passenger trains. The bridge also serves city buses and the Portland Streetcar, as well as bicycles, pedestrians, and emergency vehicles. Private cars and trucks are not permitted on the bridge. It is the first major bridge in the U.S. that was designed to allow access to transit vehicles, cyclists and pedestrians but not cars.
Bicycle use in Portland, Oregon has been growing rapidly, having nearly tripled since 2001; for example, bicycle traffic on four of the Willamette River bridges has increased from 2,855 before 1992 to over 16,000 in 2008, partly due to improved facilities. The Portland Bureau of Transportation says 6% of commuters bike to work in Portland, the highest proportion of any major U.S. city and about 10 times the national average.
The A and B Loop is a streetcar circle route of the Portland Streetcar system in Portland, Oregon, United States. Operated by Portland Streetcar, Inc. and TriMet, it is made up of two separate services: the 6.1-mile (9.8 km) A Loop, which runs clockwise, and the 6.6-mile (10.6 km) B Loop, which runs counterclockwise. The route travels a loop between the east and west sides of the Willamette River by crossing the Broadway Bridge in the north and Tilikum Crossing in the south.
The Madison Street Bridge, or Madison Bridge, refers to two different bridges that spanned the Willamette River in Portland, Oregon, from 1891 to 1900 and from 1900 to 1909. The bridges connected Madison Street, on the river's west bank, and Hawthorne Avenue, on the east bank, on approximately the same alignment as the existing Hawthorne Bridge. The original and later bridges are sometimes referred to as Madison Street Bridge No. 1 and Madison Street Bridge No. 2, respectively. The second bridge, built in 1900, has alternatively been referred to as the "rebuilt" Madison Street Bridge, rather than as a new bridge, because it was rebuilt on the same piers. Both were swing bridges, whereas their successor, the Hawthorne Bridge, is a vertical-lift-type.
