The Cameron Street Bridge is a two-lane, 208 metre (682 feet) long continuous steel girder bridge in Prince George, British Columbia. It crosses the Nechako River, connecting the city's downtown on the river's southern side, to the Hart, a residential area on the north side of the river. Construction of the bridge began in May 2008, and the bridge was completed and opened to traffic on August 24, 2009.[1]
The distinctive Howe truss design of the old bridge (since demolished) made it a city landmark.
The current bridge is actually the third bridge in the city carrying Cameron Street over the Nechako River. The original Cameron Street Bridge was built in 1916, but it was destroyed six years later due to an ice jam on the Nechako River.[1]
The second Cameron Street Bridge, a single-lane wooden Howe truss bridge, was built in 1931. Traffic was directed over the single-lane structure by means of traffic signals located at both ends of the bridge. The second bridge was closed in September 2005 due to structural problems. Due to the bridge's unique design, various ideas about saving the structure were considered (such as conversion to a pedestrian-only bridge). Eventually, the decision was made to demolish the old bridge and replace it with the current modern structure. However, the city decided to preserve the bridge's history by building a replica Howe truss bridge (with informative signage) carrying foot traffic nearby in Cottonwood Island Park.[2]
A covered bridge is a timber-truss bridge with a roof, decking, and siding, which in most covered bridges create an almost complete enclosure. The purpose of the covering is to protect the wooden structural members from the weather. Uncovered wooden bridges typically have a lifespan of only 20 years because of the effects of rain and sun, but a covered bridge could last over 100 years. Once common, only about 1 in 10 survived the 20th century. The relatively small number of surviving bridges is due to deliberate replacement, neglect, and the high cost of restoration.
The Barwon River is a perennial river of the Corangamite catchment, located in The Otways and the Bellarine Peninsula regions of the Australian state of Victoria.
A truss bridge is a bridge whose load-bearing superstructure is composed of a truss, a structure of connected elements, usually forming triangular units. The connected elements may be stressed from tension, compression, or sometimes both in response to dynamic loads. The basic types of truss bridges shown in this article have simple designs which could be easily analyzed by 19th and early 20th-century engineers. A truss bridge is economical to construct because it uses materials efficiently.
The Broadway Bridge is a vertical-lift bridge across the Harlem River Ship Canal in the borough of Manhattan in New York City. It connects the neighborhoods of Inwood on Manhattan Island and Marble Hill on the mainland. The bridge consists of two decks. The lower deck carries Broadway, which is designated as U.S. Route 9 at this location. The upper deck carries the New York City Subway's IRT Broadway–Seventh Avenue Line, serving the 1 train.
The Washington Avenue Bridge carries County Road 122 and the METRO Green Line light rail across the Mississippi River in Minneapolis and connects the East Bank and West Bank portions of the University of Minnesota campus. The bridge has two decks, with the lower deck designated for motor vehicle traffic and light rail trains and the upper deck used for pedestrians and bicycles. It is a utilitarian structure with simple architecture, but it has cultural significance because thousands of students, faculty, staff, and visitors walk across it every day.
The Cambie Bridge is a six-lane symmetric, precast, varying-depth-post tension-box girder bridge spanning False Creek in Vancouver, British Columbia. The current bridge opened in 1985, but is the third bridge at the same location. Often referred to as the Cambie Street Bridge, it connects Cambie Street on the south shore of False Creek to both Nelson and Smithe Streets in the downtown peninsula. It is the easternmost of False Creek's fixed crossings; the Burrard and Granville bridges are a little more than a kilometre to the west, and the new Canada Line SkyTrain tunnel is built just west of the Cambie Bridge.
The McKinley Bridge is a steel truss bridge across the Mississippi River. It connects northern portions of the city of St. Louis, Missouri with Venice, Illinois. It opened in 1910 and was taken out of service on October 30, 2001. The bridge was reopened for pedestrian and bicyclists on November 17, 2007 with a grand re-opening celebration. Since December 2007, McKinley has been open to vehicular traffic as well. It is accessible from Illinois State Route 3 in Illinois and from the intersection of Salisbury and North 9th Street in the City of St. Louis. The bridge carried both railroad and vehicular traffic across the Mississippi River for decades. By 1978, the railroad line over the span was closed, and an additional set of lanes was opened for vehicles in the inner roadway.
The Huey P. Long Bridge, located in Jefferson Parish, Louisiana, is a cantilevered steel through-truss bridge that carries a two-track railroad line over the Mississippi River at mile 106.1, with three lanes of US 90 on each side of the central tracks. It is several kilometers upriver from the city of New Orleans. The East Bank entrance is at Elmwood, Louisiana, and the West Bank at Bridge City.
The Homestead Grays Bridge, also known as the (Homestead) High Level Bridge, was built in 1936 and spans the Monongahela River between Homestead Borough and the southernmost tip of Pittsburgh's Squirrel Hill neighborhood. It is notable as the first bridge to incorporate the Wichert Truss, which uses a quadrilateral shape over each support, into its design. This made the truss statically determinate, so that forces in the structural members could be calculated.
Tom Uglys Bridge are two road bridges, completed in 1929 and 1987, that carry the Princes Highway across the Georges River in southern Sydney, in the state of New South Wales, Australia. The bridges link the St George area at Blakehurst to the Sutherland Shire at Sylvania. Tom Uglys Bridge is one of six major road crossings of Georges River.

It is approximately three miles west of the town of McKenzie Bridge which is named after the bridge. It is the fourth covered bridge built on the site. The bridge is well maintained and open to traffic. The Belknap Bridge is listed on the National Register of Historic Places.
The Second Street Bridge is a one-lane, single-span truss bridge in Allegan, in the U.S. state of Michigan, that carries Second Street over the Kalamazoo River. It is a Michigan State Historic Site, a National Historic Civil Engineering Landmark, and is listed on the National Register of Historic Places. Built in 1886, the bridge replaced an earlier wooden structure. In the early 1980s, the bridge underwent significant renovation.
On May 23, 2013, at approximately 7:00 pm PDT, a span of the bridge carrying Interstate 5 over the Skagit River in the U.S. state of Washington collapsed. Three people in two different vehicles fell into the river below and were rescued by boat, escaping serious injury. The cause of the catastrophic failure was determined to be an oversize load striking several of the bridge's overhead support beams, leading to an immediate collapse of the northernmost span.
Arch Street Bridge is Parker truss bridge over the Passaic River in Paterson, New Jersey. It was built in 1907 and rehabilitated in 1997. It was the third structure built at the location within a few years, the other having been destroyed by floods in 1902 and 1903. The bridge was once a crossing for the Public Service trolley lines.
