  1. TYPES of BRIDGES

  2. Beam Bridge- Consist of a beam/girder spanning the gap between two pillars

  3. Beam Bridges The 26-mile Jiaozhou Bay bridge, which was built over the course of four years for $1.5 billion, links China’s eastern port city of Qingdao to an offshore island, Huangdao, It is supported by more than 5,000 pillars, is expected to carry more than 30,000 cars per day. The Confederation Bridge spans the Abegweit Passage of Northumberland Strait. It links Prince Edward Island with mainland New Brunswick, CA. (Span 12,900 m)

  4. Arch Bridge- Arches are curved and carry weight outward along the curve to the supports at each end called abutments

  5. Arch Bridges The Garabit Viaduct is a railway arch bridge spanning the River Truyère near Ruynes-en-Margeride, Cantal, France, in the mountainous Massif Central region. (Length 565 m) The Iron Bridge crosses the River Severn in Shropshire, England. It was the first arch bridge in the world to be made of cast iron, a material which was previously too expensive to use for large structures

  6. Trusses and Struts-Truss bridges are similar to beam bridge, but much stronger- Connected by members that support the load. - Most truss supports consist of members interconnected in triangles, a strut connects these trusses together

  7. Truss Bridges The Forth Bridge is a cantilever railway bridge over the Firth of Fort in the east of Scotland, 9 miles (14 kilometres) west of central Edinburgh. It was opened on 4 March 1890 and spans a total length of 8,296 feet The Quebec Bridge is a road, rail and pedestrian bridge across the lower Saint Lawrence River to the west of Quebec City, and Lévis, Quebec, Canada. The project failed twice, at the cost of 88 lives, and took over 30 years to complete. (length 979 m)

  8. Suspension Bridges-Cables support bridge from above the pillars and are secured at either end at points called anchorages

  9. Suspension Bridges The Lions Gate Bridge, opened in 1938, officially known as the First Narrows Bridge, is a suspension bridge that crosses the first narrows of Burrard Inlet and connects the City of Vancouver, British Columbia. (Length 1823 m)

  10. The Golden Gate Bridge is a suspension bridge spanning the Golden Gate strait, the mile-wide, three-mile-long channel between San Francisco Bay and the Pacific Ocean (Length 2737 m)
