Bridges Disasters



1. Schoharie Creek Bridge Disaster:

Schoharie Creek Bridge

The Schoharie Creek Bridge was a New York State Thruway bridge over the Schoharie Creek near Fort Hunter and the Mohawk River in New York State. On the morning of April 5, 1987, during a high spring flood, the Schoharie Creek Bridge collapsed. A snowmelt combined with rainfall totaling 150 mm (5.9 in) produced an estimated 50-year flood on the creek. Pier three was the first to collapse, which caused the progressive collapse of spans three and four. Ninety minutes later pier two and span two collapsed. Two hours later pier one and span one shifted. More details





2. Tacoma Narrows Bridge Disaster:

Tacoma Narrows Bridge

The 1940 Tacoma Narrows Bridge, the first Tacoma Narrows Bridge, was a suspension bridge in the U.S. state of Washington that spanned the Tacoma Narrows strait of Puget Sound between Tacoma and the Kitsap Peninsula. It opened to traffic on July 1, 1940, and dramatically collapsed into Puget Sound on November 7 of the same year. At the time of its construction (and its destruction), the bridge was the third-longest suspension bridge in the world in terms of main span length, behind the Golden Gate Bridge and the George Washington Bridge. More details





3. Cypress Street Viaduct Disaster:

Cypress Street Viaduct Disaster

The Cypress Street Viaduct, often referred to as the Cypress Structure, was a 1.6 mile long, raised two-tier, multi-lane (four lanes per deck) freeway constructed of reinforced concrete that was originally part of the Nimitz Freeway (State Route 17, and later, Interstate 880) in Oakland, California. It replaced an earlier single-deck viaduct constructed in the 1930s as one of the approaches to the San Francisco–Oakland Bay Bridge. It was located along Cypress Street between 7th Street and Interstate 80 in the West Oakland neighborhood. It officially opened to traffic on June 11, 1957 and was in use until the 1989 Loma Prieta earthquakeMore details





4. Mianus River Bridge Disaster:

Mianus River Bridge

The Mianus River Bridge is a span that carries Interstate 95 over the Mianus River in the Cos Cob section of Greenwich, Connecticut. It is the second bridge on the site. The original bridge collapsed in 1983, killing three motorists. The replacement span is officially named the Michael L. Morano Bridge, after a state senator who represented Greenwich. The collapse was caused by the failure of two pin and hanger assemblies that held the deck in place on the outer side of the bridge, according to an investigation by the National Transportation Safety Board. Rust formed within the bearing of the pin, exerting a force on the hanger which was beyond design limits for the retaining clampsMore details





5. Cline Avenue Bridge Disaster:

Cline Avenue Bridge Disaster

State Road 912 (SR 912), known along its entire length as Cline Avenue, is a freeway north of the combined Interstate 80/I-94/U.S. Route 6 (I-80/I-94/US 6, Borman Expressway), and a local access road serving Griffith south of the Borman. The portion of Cline Avenue marked as SR 912 is 11.69 miles (18.81 km) long. On April 15, 1982, part of a ramp under construction collapsed during concrete pouring operations near the Indiana Harbor and Ship Canal, killing fourteen highway workers and injuring eighteen more. In 1987, the state designated the route between US 12 and the Indiana Toll Road as the Highway Construction Workers Memorial Highway. More details





6Second Narrows Bridge Disaster:

Second Narrows Bridge Disaster

The Second Narrows Bridge (Ironworkers Memorial Second Narrows Crossing or Ironworkers Memorial Bridge), is the second bridge constructed at the Second (east) Narrows of Burrard Inlet in Vancouver, British Columbia, Canada. Originally named the Second Narrows Bridge, it connects Vancouver to the North Shore of Burrard Inlet, which includes the District of North Vancouver, the City of North Vancouver, and West Vancouver. It was constructed adjacent to the older Second Narrows Bridge, which is now exclusively a rail bridge. The First Narrows Bridge, better known as Lions Gate Bridge, crosses Burrard Inlet about 8 kilometres (5.0 mi) west of the Second Narrows. More details





7Quebec Bridge Disaster:

Quebec Bridge Disaster

The Quebec Bridge is a road, rail and pedestrian bridge across the lower Saint Lawrence River between Sainte-Foy and Lévis, Quebec, Canada. The project failed twice, at the cost of 88 lives, and took over 30 years to complete. After four years of construction, the south arm and part of the central section of the bridge collapsed into the St. Lawrence River in just 15 seconds. Of the 86 workers on the bridge that day, 75 were killed and the rest were injured, making it the world's worst bridge construction disaster. Of these victims, 33 (some sources say 35) were Mohawk steelworkers from the Kahnawake reserve near Montreal; they were buried at Kahnawake under crosses made of steel beams. More details





8Lacey V. Murrow Bridge Disaster:

Lacey V. Murrow Bridge Disaster

The Lacey V. Murrow Memorial Bridge is one of the Interstate 90 floating bridges that carries the eastbound lanes of Interstate 90 across Lake Washington from Seattle to Mercer Island, Washington. Westbound traffic is carried by the Homer M. Hadley Memorial Bridge running parallel to it. The Lacey V. Murrow Memorial Bridge is the second-longest floating bridge on Earth at 6,620 ft (2,020 m), whereas the longest is the Governor Albert D. Rosellini Bridge—Evergreen Point just a few miles to the north on the same lake, opened 76 years later. The third-longest is the Hood Canal Bridge, also in Washington State, about 30 miles (48 km) to the northwest of the Evergreen Point Floating Bridge. More details
