The Broadway Bridge (1913) is a Rall-type bascule bridge spanning the Willamette River in Portland, Oregon, United States; Portland's first bascule bridge; intended and continues to hold the distinction of the longest span of its bascule design type in the world; and is listed on the National Register of Historic Places (November 2012).
History and description
The bridge was intended to be the world's largest bascule bridge and there was competition between the Strauss, Scherzer, and Rall bascule design patent holders. The "Rall" was selected based on cost,
Ralph Modjeski (engineer) designed the structure and opened on April 22, 1913, at a cost of $1.6 million. The bridge name derives from the street it carries, Broadway, although at the time Broadway ended at the east bank of the river and the extension of the street by bridge would encounter 7th Avenue on the west bank; the latter was renamed.
The bridge has four vehicle lanes (two lanes in each direction) that in 2001 carried about 27,000 vehicles per day, is a major bicycle route over the river by more than over 2,000 crossing daily, and a pair of 11-foot (3.4 m) wide sidewalks. On average, there are about 25 incidents per month of river traffic openings of the bridge.
The bridge was originally black, matching the nearby Steel and Hawthorne spans, but Portland architect Lewis Crutcher suggested (1961) each have its own distinct color. The Broadway Bridge was repainted "Golden Gate" red (also known as international orange) in 1963.
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. The Lovejoy Viaduct was removed in 1999 as part of the $10 million construction of the shorter Lovejoy Ramp that opened in September 2001. 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. The renovation was completed in February 2005.
In July 2010 the bridge was closed to all traffic for two months in order to re-establish the streetcar route that previously used the bridge until 1940, and extend the Portland Streetcar system. Progress was sufficient to reopened two of four lanes of the bridge on September 4. The trolley buses also used the Broadway Bridge from 1937 to 1958. The new streetcar line opened in September 2012.
In popular culture
The Broadway Bridge is prominently featured in the climax of the film Untraceable (2008). 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. The scene was filmed both on location as well as on a studio sound stage.
In the ilm, Bandits (2001), Joe Blake (Bruce Willis) and Terry Collins (Billy Bob Thornton) are driving across the Broadway Bridge when their stolen car runs out of gas. They leave the car on the bridge, and when Terry returns with gas, he finds the police surrounding their car; Terry evades police attention when he inconspicuously turns around and descends on the west side of the bridge a set of stairs that open onto Naito Parkway, where Kate Wheeler (Cate Blanchett), who is driving a speeding car, hits him.
