7 History of Bridge Element Data The aftermath of two dramatic and fatal bridge failures -- first the Silver Bridge in West Virginia in 1967 and later the Schoharie Creek Bridge in New York in 1983 (Swenson and Ingraffea 1991, Small et al.

Literature Review 9 Bridges and elements in different external environments deteriorate differently. For example, bridges subject to higher traffic volumes may deteriorate faster, and so may external girders exposed to more road salt or water.

10 Bridge Element Data Collection and Use Outside of the United States, existing BMSs also typically utilize an element data framework. Shortly after development of the Pontis BMS in the United States, Stantec developed the first BMS in Canada for the Ontario Ministry of Transportation (Thompson et al.

Literature Review 17 Another category of bridge element models is mapping models, which predict NBI GCRs based on bridge element data. Since the 1990s, with the start of CoRe element data collection, an associated interest and need arose for a mapping method between the two.
