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. [3] It was added to the National Register of Historic Places in November 2012. [2] [4]

History and description

The bridge was anticipated to be the world's longest bascule bridge and there was competition between the Strauss, Scherzer, and Rall bascule design patent holders. [5] The "Rall" was selected based on cost. [1] [6]

Ralph Modjeski designed the structure, [7] which opened on April 22, 1913, at a cost of $1.6 million. It was the world's longest double-leaf bascule bridge, of any bascule type, at the time. [1] The bridge's name derives from the street it carries, Broadway, but at the time of the bridge's construction that street name was in use only east of the river. The westside portion of what is now Broadway had been named 7th Avenue, but was renamed Broadway when the bridge opened and connected the two streets. [1]

The bridge has four vehicle lanes (two lanes in each direction) that in 2006 carried about 30,000 vehicles per day. [1] It is also a major bicycle route over the river with more than 2,000 crossings daily in 2005, [8] and has a pair of 11-foot (3.4 m) wide sidewalks. On average, the bridge's draw span is opened about 25 times a month. [5]

In 1927–28, a 2,000-foot (610 m)-long [9] viaduct was built from the bridge's west deck, extending due west above Lovejoy Street to 14th Avenue, providing access to and from the bridge that had previously been blocked by railroad yards. This viaduct was known as the Lovejoy Ramp. A shorter ramp rising from Northwest 10th Avenue at Irving Street and connecting to the easternmost portion of the new Lovejoy viaduct was built in 1927, but not opened, due to delays to the start of work on the Lovejoy viaduct's western section (west of 10th), [10] and did not open until October 1928. [11] Construction of the long viaduct section from 10th to 14th began in mid-1928, and the viaduct opened in December 1928. [12]

The bridge was originally black, in common with the nearby Steel and Hawthorne spans, but Portland architect Lewis Crutcher suggested in 1961 that each have its own distinct color. [13] The Broadway Bridge was repainted "Golden Gate" red [1] [14] [15] (also known as international orange) [16] in 1963. [17]

The bridge was added to the National Register of Historic Places in November 2012. [2] [4]

Public transit use

Streetcars originally crossed the bridge from its opening in 1913 until 1940, [18] but by at least 1944, the abandoned tracks had been removed or paved over. Work to reinstall tracks began in 2010, [19] and streetcar service across the bridge resumed in 2012. [20] The Broadway Bridge was also used by trolley buses, from 1937 to 1958. [21] In addition to the Portland Streetcar's A Loop and B Loop lines, one TriMet bus route currently uses the bridge, route 17-Broadway. [22]

Modifications and repairs

Because it is such a complicated bridge there have been frequent repairs to its structure and mechanicals. In 1948, the concrete deck was replaced with steel grating. During 1982, bicycle access was improved through an $18,000 signal and sidewalk upgrade. In order to improve access and reduce energy costs, the sidewalks and lighting were replaced in 2000–2001. [23] The Lovejoy Ramp, the long viaduct to and from 14th Avenue, was removed in 1999 as part of a $12.4 million [24] reconstruction, intended to open up the site of the by-then-abandoned railroad yards for redevelopment. [25] It was rebuilt as a much shorter Lovejoy ramp, from 9th Avenue, which opened in May 2002. [24] A $28 million renovation began in February 2003. Included in this was the replacement of steel grating with a fiber-reinforced polymer composite material called DuraSpan, made by Martin Marietta Materials. [26] The renovation was completed in February 2005.

In July 2010, the bridge was closed to all traffic for two months in order to begin re-installing streetcar infrastructure, for an expansion of the Portland Streetcar system. [19] [27] Progress was sufficient to reopen two of four lanes of the bridge on September 4. [28] Streetcar-related construction continued through 2011, including installation of the overhead power equipment. The new streetcar line opened in September 2012 and was known as the CL Line (Central Loop); [20] in 2015, its name was changed to A Loop (clockwise) and B Loop (counterclockwise).

The Broadway Bridge is prominently featured in the climax of the film Untraceable (2008). [29] In the film, FBI agent Jennifer Marsh (Diane Lane) becomes stranded on the east end of the bridge after an online serial killer hacks into her car's computer. [30] The scene was filmed both on location as well as on a studio sound stage. The bridge is also a setting for the 1996 film Foxfire , its most notable appearance being in the final scene when Legs Sadovsky (Angelina Jolie) and Maddy Wirtz (Hedy Burress) decide to part ways.[ citation needed ]

The area has been undergoing significant urban renewal since the mid-1980s when it was reclassified as mixed use from industrial, including the arrival of artists, the removal of a viaduct and construction of the Portland Streetcar. It now consists of industrial building conversion to offices, high-rise condominiums and warehouse-to-loft conversions.

<span class="mw-page-title-main">Transportation in Portland, Oregon</span> Overview of movement of goods and passengers in Portland

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."

<i>Lovejoy Columns</i> Columns with murals in Portland, Oregon

The Lovejoy Columns, located in Portland, Oregon, United States, supported the Lovejoy Ramp, a viaduct that from 1927 to 1999 carried the western approach to the Broadway Bridge over the freight tracks in what is now the Pearl District. The columns were painted by Greek immigrant Tom Stefopoulos between 1948 and 1952. In 1999, the viaduct was demolished but the columns were spared due to the efforts of the architectural group Rigga. For the next five years, attempts to restore the columns were unsuccessful and they remained in storage beneath the Fremont Bridge.

<span class="mw-page-title-main">A and B Loop</span> Streetcar circle route in Portland, Oregon, U.S.

<span class="mw-page-title-main">Madison Street Bridge (Portland, Oregon)</span> Former bridge in Portland, Oregon, U.S.

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.
