It is the busiest bridge in Oregon, carrying 135,900 vehicles a day as of 2008. The upper deck carries northbound traffic; the lower deck carries southbound traffic. The bridge was designed and built by the Oregon Department of Transportation at a cost of $14 million. The lower southbound deck was opened on October 4, 1966, and the upper northbound deck on October 18, 1966. The main span of the bridge is 440 ft (130 m) long and the two side spans are 301 ft (92 m) each. The vertical clearance of the lower deck is 130 feet (40 m) and the upper deck is 20 feet (6.1 m) above the lower. The bridge is named after Philip Marquam, a state legislator and Multnomah County judge, who owned much of Marquam Hill where Oregon Health & Science University and the Veterans Affairs Medical Center now stand. At the eastern end of the bridge, on the lower deck, is a ramp stub which was intended to connect to the cancelled Mount Hood Freeway. As it has great importance, the Marquam was the first Portland bridge to undergo a seismic retrofit in 1995. It was built with economy in mind and the public reacted unfavorably to the structure's aesthetics, including a formal protest from the Portland Arts Commission. (In particular, it blocked the view of downtown from the Union Avenue Viaduct.) This led to public input in the design of the Fremont Bridge. During Mayor Vera Katz's State of the City address in 2001, she said, "It’s like having the Berlin Wall dividing east and west, with all the subtle charm of the Daytona 500 smack dab in the middle of our city." In recent years, there has been much talk about replacing this bridge. Originally, the bridge was designed with three lanes in each direction with shoulders on each deck. Today, it carries four narrow lanes and no shoulders on each deck. Options historically considered have been to reroute I-5 over the existing I-405 alignment, connecting I-84 to I-5 at the Fremont Bridge interchange, following the US-30 alignment, and removing the Marquam permanently. Another option would build a tunnel under the Willamette River approximately following the existing I-5 alignment, and removing the Marquam Bridge permanently. No proposed replacements as of 2008 have kept the existing bridge, or have made it out of committee.
The Burnside Bridge is a bascule bridge that spans the Willamette River in Portland, Oregon. The original Burnside Bridge was a swing span bridge that opened in 1894. The replacement was part of a $4.5 million bond that also included the construction of the Ross Island and Sellwood bridges. The public would later learn that the contract was given for $500,000 more than the lowest bid. Three Multnomah County commissioners were recalled as a result of the scandal, and a new engineering company assumed control of the project. The bridge opened on May 28, 1926 at a final cost of $4.5 million (including approaches). It is the only Willamette River bridge in Portland that was designed with input from an architect. This led to the Italian Renaissance towers and decorative metal railings. The bascule system was designed by Joseph Strauss and the principal engineer for the bridge construction was Gustav Lindenthal. Electric streetcar tracks were removed in the 1940s. In 1995 one of the six lanes was removed to accommodate new bicycle lanes. From March until November of 2002 the bridge went through a $2.1 million seismic retrofit, making it the first bridge operated by Multnomah County to receive earthquake protection. The bridge was recently under construction in order to replace the deck. The electric streetcar tracks, removed in the 1940s, were visible during the construction. This project was budgeted at $9 million and the majority of the work was completed on December 9, 2007. Including approaches, the Burnside has a total length of 2,308 ft (703 m) and a 251 ft (76.5 m) center span. While lowered this span is normally 64 ft (20 m) above the river. The deck is made of concrete, which factors in it being one of the heaviest bascule bridges in the United States. The counterweights, housed inside the two piers, weigh 1,700 tons. The lifting is normally controlled by the Hawthorne Bridge operator, but an operator mans the west tower during high river levels. In 1891, Burnside Street was changed from "B" street to take the name of Dan Burnside, a local businessman who was a proponent of the 1866 dredging of the Willamette River. In the 1990s the Burnside Bridge was made a Regional Emergency Transportation Route, the one non-freeway bridge to be used by emergency vehicles. The bridge provides shelter for the initially unauthorized Burnside Skatepark under the east end, and the Portland Saturday Market is held most weekends under the west end. (Wikipedia)
