Riprap protection, inspection, and maintenance were inadequate. As contributing factors, they pointed to ambiguous construction plans and specifications, an inadequate NYSTA bridge inspection program, and inadequate oversight by the NYSDOT and FHWA (NTSB, 1988). The 183-foot span had been built in 1930 and was scheduled to be replaced in 1988, according to state transportation officials. The collapse killed ten people. The report documenting the program discusses the necessity of identifying screamers,those indicators of imminent collapse that require an agency to close a bridge (Palmer and Turkiyyah, 1999). Southbound traffic . A day doesnt go by where I dont think about it. Pier two and span two fell ninety minutes after span three dropped, and pier one and span one shifted two hours after that (Thornton-Tomasetti, P. C., 1987). "It drew attention to the way that the bridges were inspected, to the degree of inspection and to the need for underwater inspection for piers and abutments," John Seligman, director of infrastructure services for Spectra Engineering, told the Post-Standard in 2007. 'Like a Bomb Going Off'. American Society of Civil Engineers, New York, New York. William Sickinger of the state police. The Thruway Bridge Collapse on J.P. Wing's Upstate New York Roads Back to New York Roads Back to Roads. Before the road could be blocked off, three more cars fell into the gap. "Affected 'to during the 2013 earthquake. The preliminary designs were similar except for the lengths of spans, one 183 meters (600 feet) and the other 165 meters (540 feet). The second section of the bridge broke off and fell into the water about 1:15 p.m. Search and rescue efforts were hampered by deep water and swift currents. Rushing back after witnesses called the state police, he found several cars and trucks parked out on the partly collapsed bridge, their drivers gawking over the edge at vehicles that had already fallen in. A tragic incredible bridge collapsed today has pushed the Capitol District into the national spotlight. National Transportation Safety Board. FORT HUNTER, N.Y. (NEWS10) - Tuesday marks 35 years since the Schoharie Creek Bridge along the New York State Thruway collapsed, killing 10 people. By nightfall the state police and volunteers from nearby towns had found at least two cars awash in the creek in addition to a tractor-trailer that was reported buried under rubble. Although the Schoharie Creek Bridge had been inspected annually or biennially since 1968, an underwater inspection of the piers footings had never been performed. . "There's a federal law, passed in 1987, that clearly states tolls collected on the Newburgh-Beacon Bridge can only be used to operate, maintain and repair the. channel undermined the New York State Thruway bridge footings at Schoharie Creek on April 5,1987; this resulted in the collapse of the bridge and the loss of 10 lives (fig. Vortexes that form at the pier or abutment remove stream bed material. The spread footing was to be protected by a layer of dry riprap. Since the collapse of the Schoharie Creek Bridge, important advances have been made. Five counties were declared as major disaster areas and eligible for Federal disaster assistance. I never will forget hearing the thunderous sound and wondered what it was., I had a choice to either go Fonda to the Thruway or Amsterdam to the Thruway, Tonko added. Earlier, a salvage crew using jackhammers and acetylene torches cleared enough debris to locate a car and found one body inside, said Maj. John Herritage, local commander of the New York State Police. A Federal Highway Administration report fourteen months after the collapse found over two-thirds of New York State's bridges to be deficient, the highest percentage in the nation. However, the investigators found that riprap weights of 4.4 to 6.7 kN (1,000 to 1,500 pounds) should have been specified (WJE Associates, 1987). The bridge was situated northwest of Albany in the Mohawk Valley (WJE Associates, 1987). Shortly after construction was completed, in the spring and summer of 1955, the Schoharie Creek Bridge pier plinths (shown in figure 1) began to form vertical cracks. The incident has also taught Peck to appreciate life. The National Transportation Safety Board conducted its own investigation and concluded that the probable cause of the accident was a failure to maintain riprap. A 60-foot section of the 540-foot-long bridge fell 110 feet into the creekabout 10:45 a.m. The cause of the bridge failure was determined to be scour of bed material from under the foundations of piers supporting the bridge. High water prevented rescue personnel from reaching the vehicles. I think it would be fair to say that a lot of what came out of that tragedy certainly did spark a stronger bridge program, yes, said Bryan Viggiani, a public information officer for the Department of Transportation. Bridge Collapse (2002). Changes to Engineering and Management Practices. The body could not be removed from the crushed auto for identification, he said. It was a tragedy, said Willard Peck, the Northumberland town supervisor whose mother and sister died in the raging creek. Since that time, the USGS, has been evaluating data-collec tion methods and equations for estimating scour at bridges and monitoring scour at 77 bridges in New York State. Stunned motorists and area residents who witnessed the collapse said as many as four cars and a tractor-trailer truck might have fallen into Schoharie Creek, a rushing muddy stream that had swollen to triple its normal size and flooded farms and nearby cornfields a half-mile wide. When the New York Thruway was built, I-90 was supposed to follow the Berkshire Extension (off the Mass. The riprap was also too light. The collapse of pier three caused two spans to fall into the flooded creek. 10:50. Thornton-Tomasetti, P. C. (1987) Overview Report Investigation of the New York State Thruway Schoharie Creek Bridge Collapse. Publication Date: 1988: Page Count: 176: Abstract: The National Transportation Safety Board determines that the probable cause of the collapse of the Schoharie Creek Bridge was the failure of the New York State Thruway Authority to maintain adequate riprap around the bridge piers, which led to severe erosion in the soil beneath the spread footings. Collapse of the New York State Thruway bridge over the Schoharie Creek hearing before the Subcommittee on Water Resources, Transportation, and Infrastructure of the Committee on Environment and Public Works, United States Senate, One hundredth Congress, first session, May 4, 1987. (function() { var cp = document.createElement("script"); cp.type = "text/javascript"; " Collapse of New York Thruway (I-90) Bridge over the Schoharie Creek, near Amsterdam, New York, April 5, 1987," Highway Accident Report NTSB/HAR-88/02, NTSB, Washington, D.C. Google Scholar . It empties into the Mohawk River about a mile north of the site of the collapse. He continued his education at Union College in Schenectady, where he played on the basketball team. 2). He said the collapsing bridge made a rumbling sound, like rocks rolling down a hill.. 13 Investigates has learned the bridge involved in the 1987 Thruway bridge collapse was last examined in June. Sid Brown, who was the Gazettes chief photographer in 1987, was about a half mile away, on Route 5S, when the first section of the bridge collapsed. Thirty miles upstream, at the Gilboa Dam, engineers opened the gates to force a rush of water through Schoharie Creek. Bridge inspections play a major role in evaluating the superstructure and substructure for deterioration to determine if maintenance is required. Salvage operations began in the afternoon as engineers and construction teams gathered at the site. ''All of a sudden I just heard this noise,'' said 15-year-old Shawn D. Jablonski, who was standing on a bridge downstream. More than 50 rescuers rushed to the scene, but could. (1987). The towers top out at 100 feet higher than the former Tappan Zee Bridge. 1/2.

By the continuity equation Q = Av (where Q = flowrate, A = cross-sectional area, and v = velocity), if the channel cross-sectional area decreases then the velocity must increase, resulting in an additional lowering of the channel bottom elevation. One car and one tractor-semitrailer were on the bridge when it collapsed. Sunoco (914) 478-2072. The geologic/geomorphic and weather factors . var _cpmp = _cpmp || []; _cpmp.push(cpo); A cofferdam was constructed around the failed piers and the site was dewatered and excavated, both to aid the investigation and the construction of the replacement bridge (WJE Associates, 1987). The Schoharie Creek Bridge collapsed on the morning of April 5, 1987, after three decades of service. New York State Thruway bridge collapse [ edit] On the morning of April 5, 1987, after 30 years of service, two spans of the New York State Thruway bridge over Schoharie Creek near Fort Hunter collapsed. A state Thruway bridge over the Schoharie Creek collapsed in 1987, killing 10. In the end, 10 people were dead in a catastrophe that seemed unimaginable the collapse of a state Thruway bridge over the Schoharie Creek and five vehicles falling into deep, surging water. Search teams combing the flooded Schoharie Creek on Monday recovered the bodies of three people killed in the collapse of a New York Thruway bridge, . Obviously, this was not done, and it would have been difficult to extend the reinforcement through the columns without replacing the columns. Thornton-Tomasetti found six items that aggravated the tendency for scour (pp. Once the backfill had been exposed, the years of peak flows removed the backfill material, and the backfill , in turn, as replaced by sediment settling into the scoured holes (WJE Associates, 1987). The bridge, which carried an average of 15,519 cars daily throughout the year, was completed in 1956, two years after the first sections of the Thruway opened. A study conducted in 1989 revealed that 494 bridges failed during the years 1951 and 1988 as a result of hydraulic conditions, primarily due to scouring (Huber, 1991). The bridge design originally called for leaving the sheet piles (which were used to keep water out of the excavation area during construction) around the piers (Levy and Salvadori 1992). . Thornton, C. H., Tomasetti, R. L., and Joseph, L. M. (1988). [ Page B2. ] Shortly before 11 o'clock this morning, a bridge on the New York State throughway suddenly collapsed into the raging Schoharie Creek. "It's an incredible tragedy," said Alexander Levine, the Thruway Authority's executive director. Scouring failures also sparked the much-needed research for detecting scour potential. The plinth could not resist the bending stresses between the two columns. The piers and spans are shown in Figure 2. The bridge was constructed in the 1970s and was among the infrastructures jolted by the 7.2-magnitude earthquake that hit Bohol in 2013. The analysis should also include the effects of potential land use changes upstream, such as increases in runoff from development and associated paving. Saratoga County creates multi-agency support system for first responders, Schenectady-Belmont cheerleaders raising money to compete in national championship, Dining for Dollars returns full-swing for its 17th year supporting local non-profits in Schenectady. While the bridge was in service, the inspection procedures used were not sufficient to detect the scour. In Albany, switchboards at the Thruway's headquarters were inundated with telephone calls from relatives and friends of travelers who feared the worst. ''I'm totally amazed - I truly cannot believe this,'' said James A. Martin, deputy executive director of the New York State Thruway Authority, who said Thruway bridges were designed to withstand what engineers call the ''100-year storm,'' the worst storm expected in a century. The Thornton-Tomasetti report notes where riprap is used to prevent scour, inspection and restoration of protective riprap should be performed after every significant flood to avoid progressive damage, and the replacement stones used should be heavier than those which were observed to shift. In 1987 the nearby Interstate 90 (New York Thruway) bridge collapsed during a flood when excessive scouring undermined a central pier, killing 10 people. important examples in recent decades include the Schoharie Creek bridge on the New York Thruway in 1987 during intense rain, the San-Francisco-Oakland Bay Bridge in . Berms built in 1963 directed floodwaters under the bridge. This is a digitized version of an article from The Timess print archive, before the start of online publication in 1996. The design firm developed two designs for the crossing of the Schoharie Creek. The upstream end of pier 3 fell into a scour hole approximately 3 meters (9 feet) deep (NTSB, 1988). This is why we give the book compilations in this website. I was driving up from Schoharie County to Montgomery County, Tonko said in a phone interview on Tuesday. "We don't know how it happened. Witnesses said the tractor trailer plunged straight into the creek, leaving only its exhaust pipe visible above the roiling water. Sewer Septic Tank. The NYS Thruway bridge crossing the Schoharie Creek in eastern NYS collapsed during the morning twilight hours of April 5, 1987. An underwater investigation 15 days after the collapse showed evidence that water erosion beneath three of the bridge piers caused the span to shift and give way. Scour removes material through three mechanisms (Thornton et al., 1988, Palmer and Turkiyyah, 1999). cp.async = true; cp.src = "//www.cincopa.com/media-platform/runtime/libasync.js"; Schoharie Creek Bridge collapse Coordinates: 425551N 741641W The Schoharie Creek Bridge was a New York State Thruway ( I-90) bridge over the Schoharie Creek near Fort Hunter and the Mohawk River in New York State. The Thruway bridge collapse in 1987 was the biggest incident in that round of flooding, no thanks to heavy rainfall and heavy snowmelt. On April 5, 1987 it collapsed due to bridge scour at the foundations after a record rainfall. Is the worlds richest person the worlds worst boss? These are: Clearly, at a bridge pier, all three processes occur and are additive. An embankment west of the creek channel increased flood velocities. A curve in the river upstream of the bridge directed a higher-velocity flow toward pier 3. ''It's too high, too fast and too dirty,'' Maj. Edward Vanderwall, who commands the troopers who patrol the toll road, said of the creek. It carried more than 80 million vehicles last year. However, a necessary secondary cause was unstable propagation of a single crack in the pier. On April 5, 1987, the New York State Thruway bridge over Schoharie Creek collapsed without warning. However, a necessary secondary cause was unstable propagation of a single crack in the pier. These items did not contribute to the collapse of the Schoharie Creek Bridge (Thornton-Tomasetti, P. C., 1987). The National Transportation Safety Board investigated the accident and determined the bridge fell because piers holding it up were not protected from scour, erosion caused by the flow of water. Five vehicles fell into the river, and ten occupants died. In the muddy waters below, sections of the bridge's green steel underside could be seen, along with parts of the roadway. Therefore, instead of dropping slowly into the scour hole, the plinth cracked suddenly. There were several other problems that occurred shortly after the completion of the bridge. New York State is home to approximately 17,450 highway bridges, about 44 percent of them owned by the State Department of Transportation (NYSDOT), roughly 50 percent owned by municipalities, and the rest owned by state and local authorities (such as the State Thruway Authority), commissions (such as the Capital District State Park Commission), and .
