    The Steel Bridge is a through truss, double lift bridge across the Willamette River in Portland, Oregon, United States. It carries railroad and pedestrian traffic on the lower deck, and the Pacific Highway West No. 1W (former Oregon Route 99W), MAX Light Rail and a vintage streetcar on the upper deck, making it 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 bridge was completed in 1912 and replaced the Steel Bridge that was built in 1888 as a double deck swing span bridge (photo). It was the first railroad bridge across the Willamette River in Portland. The name originated because steel, instead of wrought iron, was used in its construction.

    The structure was built by Union Pacific Railroad and the Oregon Railway and Navigation Company at a cost of $1.7 million. It opened in July of 1912 to rail traffic and on August 9, 1912 to automobiles. Between 1984 and 1986 the bridge underwent a $10 million rehabilitation including MAX construction.

    In 2001, a 220 ft (67 m) long and 8 ft (2.5 m) wide cantilevered walkway was installed on the southern side of the bridge's lower deck as part of the Eastbank Esplanade construction, making a total of three publicly accessible walkways, including two narrow sidewalks on the upper deck. The bridge is currently owned by Union Pacific with the upper deck leased to Oregon Department of Transportation, and subleased to TriMet, although the City of Portland is responsible for the approaches.

    The lower deck of the bridge was threatened by major floods in 1948, 1964, and 1996.

    The lift span of the bridge is 211 ft (64 m) long. At low river levels the lower deck is 26 ft (7.9 m) above the water and 163 ft (50 m) of vertical clearance is provided when both are raised. Because of the independent lifts, the lower deck can be raised to 72 ft (22 m), telescoping into the upper deck but not disturbing it. Each deck has it own counterweights, two for the upper and eight for the lower, totaling 9,000,000 lb (4,100 metric tons).

    The machinery house is above the upper deck lift span with an operator's room suspended below the house so that the operator can view river traffic as well as the upper deck. The average daily traffic in 2000 was 23,100 vehicles (including many TriMet bus lines), 200 MAX trains, 40 freight and Amtrak trains, and 500 bicycles. The construction of the lower deck walkway connected to the Eastbank Esplanade resulted in a sharp increase in bicycle traffic, with over 2,100 daily bicycle crossings in 2005. (Wikipedia)

      Wow. I didn't even recognize the bridge at first, I live about a mile away and work in Portland. I've been across the bridge a few hundred times on the train, and light rail above. Awesome bridge, great shot, and very interesting processing.

      How do you get the copper type look in the image? Is that actually part of the image or is that a photoshop created quality. Would you be willing to share suggestions for achieving that look?
